[Q] What does a Kernel do? - HTC EVO 3D

Pardon my ignorance, but what is the Kernel?

A kernel is simply a director for the computer in movie analogy. It controls the scripts( what gets done and how), the cast(Bluetooth , video, Internet so on), and production( who goes where, how and why.) it is the main software that gets loaded and talks to other software for hardware( such as video output, phone dialing drivers etc.). Every operating system is a kernel. ALL other software in the phone, no matter what is..is the supporting cast. In a nutshell, it is what guides, and makes computers work with other parts of it..both hardware and software.

Hey, thanks! I really appreciate it. No wonder people are so excited with a OP named NETARCHY on de DEV forum.

Another way I like to think about it is this...You phone has a chip on it that has many of the devices that used to be seperate (processsor, GPS, wifi). Now they are all rolled up in one. A KERNEL is like that as well. You have drivers on your windows 7 machine that contrl different devices. A KERNEL IS like many drivers in one.

Bluetooth function on Éclair ?

what are the odds that in the new version of android , the issue with bluetooth file transfer will be fixed ?
doubt it, i dont think its a bug but more a compagny policy.
they dont want you to send apps and games to oher phones
i think we have a better chance with the xda community here for developing/porting a proper bluetooth stack to our hero` s
there is a lot more you can do with a proper bluetooth stack than sending files, you know. so i doubt this is a company policy thing but rather a BIG failure to deliver what has been standard in mobile devices for years now. (especially for handsets in this price range)
coming from the iphone, i learned that all the "BT is necessary" chants were a bit overrated; I didn't know it was not possible until way after I upgraded to the 3G. I never used it or saw the need for it.
In the beginning BT filetransfer was 'cool'; "wow I can send a picture! or a MP3 !!"
But now I would just email it, even if the person is standing next to me.
A2DP I can understand. But all other functions like "cool! I can use my phone as a mouse for my computer!!" for me got old 4/5 years ago.
Still, if people want it, you could just write a program, no?
No, obviously it is not possible to "just write a program" if there is no API for Bluetooth file transfer and there is no information on how to do it without an API.
There are now several programs that can do BT file transfer on other Android phones, but none of them work on the Hero.
And you can use only mail if the receiver can also use mail. My BT carkit certainly can't use mail.

Well, almost true.
There's an app in the market called "Bluetooth File Transfer" which allows you to send and receive files by Bluetooth and doesn't require a rooted phone.
Sounds great, but.... (yes there's a but!)
You can only receive files being sent from another Android user via "Bluetooth File Transfer"
See http://www.medieval.it/content/view/61/85/

Does it work on your Hero? It doesn't on mine (GSM Hero). The market description still says "Currently, doesn't work on HTC Hero and Samsung Galaxy, but we are working on it." (http://www.cyrket.com/package/it.medieval.blueftp)
Same problem with Androbex: "Reported not to work on HTC Hero and Samsung Galaxy. you can try yourself and tell us."
As far as I know, neither the Hero kernel nor a Hero image for the emulator is available at this time, so it is a lot more complicated to develop such things which are not covered by the API.

I have another but on this. It doesn't just have to be to another Android phone, I can easily send to my Sony Ericson & LG & Moto friend's phones.
Although I'm on a rooted G1, so take that with a grain of salt.
However you are right about not working on a Hero.

As I said, it says that you can only *receive* files from another user of this software. I always presumed that sending would be ok!

I installed it on my Hero, and it seems to run ok (i.e. no obvious errors) but as soon as I saw that I can only receive from another phone running this software, I dismissed it. I seldom use BT file transfer anyway, and this restriction would've made it pointless for the limited occasions that I might use it.
I will give it a try today though, and see what happens, but I'm also on a rooted device so this may make a difference.

Ok, when I start the application it tells me that is has successfully started the "Bluetooth file receiving" and "Bluetooth file sharing" service.
However, I tried to pair with my laptop and I got an error message that it couldn't start the OBEX FTP service. So, it looks like it doesn't work at all for devices not running their software. I do wonder though if it would work between two devices running the software simply because it looks like they don't use OBEX FTP.
Regards,
Dave
maybe someone can make a wifi based peer to peer app FTP orso
at least then we can send stuff
I think dismissing it as simply being 'cool', is incorrect.
I know alot of people that arn't 'smartphone' savvy and don't have email accounts that they use on the phone or have internet access on the phone for that matter. They tend to use the phones mostly for (shock horror) making call and taking pics etc.
There have been several instances when they like a picture/video clip or something and want to send/receive via bluetooth.
They are somewhat surprised when I say I can't do that, especially after I've shown them all the other clever things I can do on the phone...
Zuber
Bluetooth
Begin rant:
I know everyone keeps saying you should sync your entire life with Google's servers (as that’s the point of having an Internet device) but there are times when a quick sync with Outlook (or another client) is desirable just to back-up your contacts or to grab a file/contact through the use of Bluetooth. Hell, that’s what the technology was created for!
Yes, I know everything is online with Android, but using BT to sync is something I took for granted with my Win Mobiles and Symbian devices. With me it’s a privacy issue, I don't want my entire life to be blasted off into the ether, transmitted across the globe, stored on a sever (in a country for which server security may not be a top priority i.e. Korea) and back again just to ensure my phone calendar is up-to-date with my computer's calendar.
From my phone in my pocket to the computer sitting less than a foot away on my desk, Bluetooth seems the best solution.
Yes, there's USB but that means plugging in a cable...
End Rant.
If you have a WiFi router (or access point) it's possible to use an ftp server on the hero and an ftp client on the desktop (or vice versa). See FTPServer and SwiFTP Server for ftp servers.
I didn't try aFileSync yet, but from the description it looks nice.
But this doesn't help if you don't have a WiFi router avaliable, although WiFi ad-hoc mode might be possible with android-wifi-tether on rooted phones. And Wifi ad-hoc mode doesn't help if the other end has only Bluetooth.

To be honest, it's probably partially Apples fault as it took them ages to get something half resembling Bluetooth into their iPhones. Given the take up of the iPhone, it does go to show that much of the market can just live without it.
Googles "excuse", way back more than a year ago, was that they hadn't quite finalized the API and so they shipped the G1 with only support for headsets. Skip forward a year, and they've only only added a couple more profiles to their bluetooth stack, which is pretty poor going for a multi-bazillion dollar organization!

True, I know its a feature that (some) of us expect but at the end of the day the Android OS is still in its infancy. Give me Android over Symbian (which I've been using for the last couple of years) any day!
It would be nice to see things like OBEX implemented into the OS (perhaps in a future release?). But for all the small picky things that its missing, Android makes up for its 'downfalls' in a million other ways. I certainly would not switch now, I just hope that Google, HTC and all the freelance Dev's keep up their amazing work.
One final word: I'd still like to Sync with Bluetooth though!
This is not just a cool feature, it is an expected feature. To have a smartphone released without that is ridiculous, in this day and age. Unlike Apple, who have ideological reasons why they dont want it, I dont believe that Google have any reason; it is just a massive slip up, probably because they werent thinking globally.
It is the most starred/wanted issue in the Android bug/development list, higher than anything else which shows that it is pretty important to tech- savvy users as well as the average joe who takes it for granted.
People simply expect this standard functionality to be there. I never fail to be embarrassed when someone asks me to bluetooth a photo to their crappy Nokia and I admit I cannot.
I could on my Jam, I could on my Touch, I could on my Diamond, but I cant on my Hero. Pathetic.
bluetooth obex on donut 1.6
hey i have been looking all over for an up to date blog on android obex development. I notice many of you guys are complaining about not having the capability. Look up Medieval software app that is freeware in the Android Market, and also have a webpage. I have used them for windows mobile. I have seen sites where people have created their own stacks and have directions to help you. I would be interested on learning how to actually do this. I know cupcake had a directory and stack for this. I would like to know if any of you know anything for the donut build. Every time I connect to my pc from medieval via my G1, i get this error "Service not found, you can't connect with target device because it lacks of the obex ftp bluetooth service"....oddly however when i linked up this app it allowed a stack to become visible underneath the vista bluetooth properties on the G1 device. it had handset and file transfer which i selected because it wasnt. Actually as im writing this i just checked again to verify the name and now i have another one! Object push! wow. so i will keep you posted. going to try harder. i think this program will work. thanks
Idea
Correct me if I'm wrong but seeing as the Blueooth standard is open and Android is opensource, how much time/effort/cost would it involve in a 3rd party dev like MoDaCo/Cyanogen implementing additional protocols into the BT stack?
A custom ROM with this feature would be an instant hit. I'd make a donation to anyone developing such a feature.

Well, it can totally be done. Im pretty sure people have made steps to do this and some 1.5 cupcake roms had support. There is many BT stacks out there and are dependent on the more primitive driver, known as the API. The Kernel is the base framework which is chosen for these Roms. Most rom developers like Cyanogen pick a certain one to fulfill an obligation, ex speed, Hero, experimiental. From what I get on here is that many of the top rom developers dont care much about BT and alot of people are waiting for BT 3.0. So in short i behind what you stated and maybe we could start a donation fund towards a developer that would be willing. Maybe theres already someone out there even! Alot is changing with Android, its exploding.

[DEV] Hardware observations

Post here about anything you might have found out about the internal NookColor hardware.
Here's one to start with:
Look at dmesg under Android. The wireless driver is TIWLAN, and a little Googling correlates the line "Chip ID is 0x4030111" with a WL1271, a TI part with 802.11b/g/n, bluetooth, and FM. However, as far as I can tell Bluetooth isn't anywhere to be seen in the Nook ROM.
This document shows the typical setup for the WL1271, which is for WiFi to connect to the host through SDIO (one of the SD/SDIO/MMC interfaces) and Bluetooth and FM to go through a UART.
There may not be antennae for BT and FM, but we should definitely look into this

Maybe not FM, but that document I linked shows a "WiLink 6.0 Solution" that uses an antenna switch so only one 2.4GHz antenna is needed for BT and WiFi.
Ohhhh, this has some interesting potential!
I got Flash 10.1 to install, but cannot get the B&N Browser to Dolphin to recognize that its installed when I try to do something with Flash (tells me I need to install it)

Interesting, but let's keep this thread on the topic of hardware.
Have you tried checking the ttys? Or even just trying to put a bluez stack + firmware taken from another device on it?
BlueTooth
Please, Oh Please, tell me that this device can do BlueTooth. The ability to add a wireless keyboard would make this device Perfect for me!!!!
Agreed, Bluetooth FTW. We could be one kernal injection away from BT!

I didn't bother; from that doc I posted there's a GPIO enable for bluetooth, and unless the BN developers were complete bozos they've turned it off and left it off in this kernel. We could go searching for it, but it would get tedious. I am willing to bet that it's referenced in the BN u-boot and kernel sources though.
The TI WLAN/BT/FM driver and firmware can be found here: http://gforge.ti.com/gf/project/wilink_drivers/
This might not be the right section. But what are the possibilities of overclocking to possibly run the tablet version of android "3.0" which is said to require 1ghz or faster processor??
This is an interesting find. My guess is that it would have been too much of a hassle for BN to get a WIFI only chip so they opted for the ready made one and disabled the rest of the functionality.
But I think until we have a cooked ROM for the Nook we won't be able to see BT any time soon. This is too stripped down an OS.

It's clear that the NC is based on TI's ebook reference platform. Given the amount of TI silicon in there I wouldn't be surprised if TI cut them a deal on this WiFi module such that it was cheaper than another company's WiFi-only one. It's not clear what's inside the module, and for all we know there is no BT/WiFi switch, which would make it impossible to run anything but WiFi.
As long as the module has a switch, it wouldn't make any sense for BN to hard-disable the bluetooth. There aren't that many connections just to get BT data, and I'm pretty sure the OMAP doesn't use those connections (1 GPIO, 1 UART) for anything. It would only cost a few PCB traces and maybe a pullup resistor or two, less than a couple of cents at scale.

It seems pretty unlikely, to be honest. The NC wasn't intended to run straight Android so can't see B&N being massively interested in supporting future Android versions.

That's a fairy tale. The next version of android will be 2.3, and nothing about 3.0 could be confirmed as it's likely 6 months away at least. And no one has really even confirmed anything about 2.3. It's all been sightings and rumors.
But back on topic - has anyone had a look at the TI Ebook reference material? Maybe they have a vanilla version of android that is made to work with the processor? It's possible the Nook hardware is similar or identical to some TI reference design - it is the first product based on that chip after all, maybe B&N just let TI design the thing?
EDIT: At the bottom of the page for this processor it says: "This product is intended for high-volume wireless OEMs and ODMs and is not available through distributors. If your company meets this description, please contact your TI sales office."
So Grr, looks like they're not going to share much unless you're a big company. Sometimes these guys have lots of support material for their processors, but I guess this one is too specialized.

I browsed through a bit. Looks like very well supported hardware - the driver for the WIFI chip is in the AOSP source tree, and the graphics chips is pretty common.
It would seem to me that a port of Cyanogen would be very straightforward. The missing buttons would need to be mapped to something - maybe an additional UI component which popped up for menu and back? - but other than that...doesn't look too bad. Simpler than a lot of others, maybe.
And damn, this device looks like it would be pretty quick. It's no slouch now, and with Froyo...and maybe a touch of overclocking... it would be faster than a Nexus one with absolutely killer battery life.
A very commonly available, high-quality Cyanogen tablet for $250?
Sick.
You could copy the Archos on-screen buttons (which look really annoying but are better than nothing)

Eh, as far as I can tell it's the same die as the 3630 but in a lower pin count package, without a package-on-package (DRAM/flash stacked on top) version, no camera interface, and only specced for 800MHz. The 3630 comes in 1200MHz versions, and as we've seen with the Nooter bootloader (by accident) it's possible to make this part run at least at 1GHz.
The datasheet for this part is the general 36xx series datasheet, and at 24MB isn't lacking at all (except for the DRM stuff).

There's a thread in the general section right now about a button remapping app.
I just manually did what the app does, pulled the .kl files, changed VOLUME_UP to BACK and VOLUME_DOWN to MENU, pushed the files back and rebooted.
Et Voila, Bob's yer uncle, I now have menu and back keys...at the expense of losing a couple of volume control keys about which I care not at all.
Nice.

cideko simple box

I recently got my hands on a quite interesting device, a cideko simple box.
Just for the sake of it, I'd like to hack it, and maybe even get a custom rom on it.
It's basically a set-up-multimedia-thingy-box for a TV running android, and it's pretty damn cheap.
Using adb via TCP/IP I was already able to connect and also get a rootshell (yay!)
However, it seems like no firmware files/instructions how to flash are available by the manufacturer (nay!)... I already asked them nicely, let's see what I get back.
You can find the adb bugreport output here if you're curious.
Anyone wants to help?

Saw this hardware before. 600Mhz, no openGL or any accelleration for games, nothing.
It does play back media files, but that's about it.
Very low-end chipset from Skyviia.. ARMv5TEJ at ~228 bogomips is pretty bad.
Does it support the install of apk files from USB? and does it allow flash on websites?

I have one too. I like the device and the air keyboard, plus it was pretty cheap. I was really pleased that SMB/CIFS support worked out of the box and witha few other things, but thats where it stops. The software included is the let down, not the machine itself. Video playback is out of sync 99% of the time until you fast forward and/or rewind then it magically syncs up again, only 1 CIFS connection at a time, the vast majority of apps will not install and those that do fail to run, the video software displays long file names in such a way, that you cannot determine which file is which, etc. I sent Cideko an email asking them to pretty please provide a new update addressing these issues, but I heard nothing back and I sent it months ago.
The picture is good, the device is unobtrusive and if you rename your file appropriately then it is a bearable media streamer, but it could have been the best little cheap media box ever with just a little care and attention. Disappointing that no one is interested in improving it.

Sony Security

Hi Guys,
First post here so I could'nt post in the relevent thread. It has been noticed that there is a switch on the Tablet S PCB that apparently disconnects the battery, I've opened up many devices over the years and have never seen that before - very strange if you ask me. Might be of interest to some to note that the Sony PSP used an anti hacking method that utilised the battery !!, so we may be on to something here.
On PSP a hacked battery is called "pandora battery". It is not a switch. The battery has four contacts. Two of them are the voltage contacts plus and minus and two of them send a serial signal code. With the right code, the PSP boot in a special (hidden) recovery menu. Do you have more information about the tablet battery and the switch? Pictures available?
Wouldn't the relevant thread be the ones you found out about on it?
original discovery of switch here (with pictures)
Then I brought it up in the dev thread about APX mode here
And yes it exists... can confirm it's there (at least on my 16gb model anyway)
My thoughts are is that there would be a factory cable used here (similar to the motorola factory cable) and they need to disconnect the battery for it to function as it should.
And a hunch that it could very well have something to do with APX mode, however... since people have stumbled into APX mode completely by accident with no hardware commands, that kind of contradicts that thought.
I don't have any info on the battery or the switch, I was just pointing out the strangeness of having a switch to disconnect the battery, nothing else I have ever looked at has this feature. (and I've opened up a lot of devices)
It just makes me think that there is a need to easily and repeatedly disconnect the battery during the manufacturing / assembly / repair process.
For example, does the system "know" when the battery has been disconnected and allow different operations ? - fastboot perhaps ?
I know this is all supposition and it may mean nothing at all - but the feature is bugging me - it cost money to implement and I can't help but feel it's there for a reason.
System woiuld'nt let me reply in thread I was reading - said dev section was for expert users only ??

I thought of this too but then went on to think that there's probably no way such a thing would transfer accross do android/unix codes like that. ie they use android kernels and stuff, they don't make the whole thing themselves. Plus they realised the vulnerability of it and removed it in models like the psp 3000 and go (not sure about 2000).

You're actually pretty close, I think. Android would be perfectly capable of receiving certain boot codes, but these are far more likely to be wired to the more capable micro-USB port as in just about every other Android device. While an Android kernel could theoretically receive serial codes from almost anywhere given the right instructions, Sony would probably not do this. As mentioned, the PSP's ability in this regard caused many problems.
As mentioned by the others, if someone could post some good hi-res shots of the battery and surrounding PCB or something like that, that would make it much easier.
Sony's philosophy has always been that the end user should use the product as it was built and the purpose it was built for.
They've always made hacking and rooting very difficult for users. They don't like their products being tampered with.
I can understand where they are coming from, but at the end of the day, with many phones and tablets, if root techniques and mods aren't available, many users won't buy the goods.

Just to clear things up, what works on the PSP will not, generally speaking, work on the Tablet S. They are different hardware, with different interfaces to different firmware which runs completely different software.
If we can get a look at the PCB in closer detail where the battery connects we might be able to see if there are any serial pins, but I doubt there will be. No other Sony product since has featured it (to my knowledge).

[Q] Android masquarading as iPod

I PROMISE I have Googled and searched and searched and Googled. I absolutely apologize if this is a repeat or obvious question. I hope that there is a simple answer.
To put it plainly, I am wondering if anyone has made some sort of software that would allow an android device to appear as an iPod/iPhone while attached to a media playing device via USB? Specifically, a car head-unit (radio).
My Pioneer has all kinds of wonderful abilities for talking to and controlling an apple iWhatever, but has almost nothing for other devices. And I just wonder if anyone has helped bridge this gap?
I know that when the Palm Pres first came out, the emulated being an Apple device for a while, and I thought I saw a similar software for Android once upon a time. But if it exists and works today, God knows I am not finding it. SOOOO I thought I would ask in this wonderful, singular place of knowledge, before finally giving up.
Again, I apologize if this is a redundant question. Thanks so much in advance. Have a great day!

Lemme guess-you have a AVIC head unit? If so, me too! (X910BT). I actually posed a somewhat similar question asking for information on how to program A2DP so I can spoof the Bluetooth into thinking it were a supported model so we could stream Slacker.....
Hopefully someone more knowledgeable can help us....
What is the connection method? If its USB you could try mass storage device mode just to access the files themselves assuming the player has some sort of GUI to navigate the directories.
The easiest method if you want to control audio via the phone is to just hook the headphone output into the aux. Apple's proprietary usb connection has audio out and thats how docks are able to use it.
What is the radio model and have you tried Googling for a solution. I can't believe the manufacturer would just leave all other devices in the dark, but I have seen stuff like this before.

Ummm... yes, connecting by USB. And yes I googled first. The pioneer will mount a USB mass storage device, but it is slow and lacks much in the way of functionality, such as sorting and playlists. Again, if the phone "pretended" to be an iSomething, then that would be ideal. I am wondering if such is possible.

I posted the same question a week ago with no answers. Great source of information here.
Anyway I dont think the issue is making the android system "pretend" to be an apple product as blackberries also work fine. I think droid needs a software to make it compatible wit this usb feature.
