Hello everyone,
I have searched the whole forum and all i could get hold of are either pranks or nuffin....But serious i wanna develop an android application for being able to charge through Wifi.
Because as we all know when the mobile phone is connected to a hotspot it no more uses battery power for wifi it derives totally its power throught the wifi hotspot.All we need to do is just to modulate that power to the battery charging.
Can anyone please guide me to the respected tools to be used for developing it.Be-waiting for your response.
Thank you,
Regards,
Moid.
Something like that would require special hardware.... I seem to recall seeing something like that at a convention, maybe CES?

you myt have seen something similar at a D5 show....where in it was more like a wireless charger not a wifi charger....the basic technology was that they are using carbon crystals on the device attached to mobile devcie which would viberate and tend to charge the battery and it was radio waves being used as the mode of transmission from the host device that would be connected to the power supply.

Is it so?? I doubt! The host wifi chip still consumes power from battery to stay connected, that too several times more than what is consumed by gsm radio chip. Due to this only our batteries last very less with wifi connected! AFAIK the power of wifi hotspot can NO WAY be transferred via radio handshake!

Yes, here it is... http://www.geek.com/mobile/airnergy-charges-battery-using-wi-fi-signals-1048241/
There are joke apps on the play store as well, just like there are 'solar charging' apps... but they can't really work because the hardware needed isn't there.

I may get flamed for asking this but I'm going to any way. Is it possible to tether an Ipod Touch to an Eris through bluetooth in order to share the 3g internet connection? I haven't used my Touch much at all since ive had the eris...just thought it would be convenient when wi fi isn't available.

Well, if you're not leaked then just root the phone and open wifi tether. Start the tether and then just connect the ipod touch to the access point that the phone creates.
Yeah, it should work perfect. The phone creates the Ad-Hoc network and bam, you're online.
Off note, I know for a fact that until Sony gets their heads out of their butt, the Wifi Tether won't work for the PSP (The PSP is too good for ad-hoc networks apparently).
Yep, I got it working. If you're rooted use the wireless tether app to connect through wifi. Create an SSID and PW and you're good. Still can't figure out bluetooth, but wifi works just fine for me. I only use my Touch for the games, which as of now is really the only thing Android is lacking IMHO.

Man you got that right. Too bad developers aren't able to tap into Android's true power (seems to be a software limitation, yay Google! lol...)

really? Android is the most open and I think most varied and powerful smartphone OS available ay the moment. Google is giving it away, I hardly think its limited in software in any way.

Hello, i wish to enable promiscuous mode in my atrix 4g, but found out the chipset does not allow it.
The idea is to be able to crack easy WEP networks on the road.
Alternatively i was thinking on getting a cheap netbook and hook up a more powerfull USB wifi adapter like the 2 watt alfa AWUS036NH , that supports upgradable antennas as well, and was tested working in monitor / injection mode over linux.
but got me thinking, why spend money on a netbook if maybe i can hook up the wifi usb adapter into the atrix 4g hd multimedia dock, and then use aircrack with that wifi usb tested device, instead of the onboard wifi.
In know is possible to compile aircrack into android, but the problem always relies in incompatible monitor mode onboard wifi addapters.
With this USB addapter this issue would be solved.
Another issue is power, this 2w adapter needs it. I'm pretty sure the hd dock has a powered USB hub, so that would not be an issue. I would later hock up the dock into the car battery, or maybe use like a 12v 10a/h external battery for portability.
Does anyone has done anything like this before?
i already have a rooted phone and a debian img installed.
thanks
I'm also interested in it...
Seems that some tablet (like the flytouch 3) have a native support to some tipe you USB WiFi adapters
By the way this tablet have a similar "integrated USB WiFi adapter" (RT3070 or RTL8191SU) so it have the drivers already installed and this Is the reason why it support the adapter, I think...
Different usage scenario
Does anybody know if establishing wifi/lan using usb / multimedia dock is possible?
I'm not asking for aircrack or anything like that. I use an atrix in a multimedia dock (hooked up to stereo system) as my alarm clock, tuned to an internet radio station. My wifi on this atrix has recently burned out and I'd like to get a data connection again (external wifi/lan whatever) without needing to get a data plan (or activated sim at all).
Anybody ever try this or get it working somehow? A lot of atrixes get retired due to bad wifi, but if a cheap wifi dongle and bring it back to life, it can still serve many uses!!
Thanks!

The op poses the same question as I do. It does not answer the question. Over a year has past with people's WiFi going out, new approaches or insight may have been gained in the community since then.
Since there was never an answer, a bump isn't exactly inappropriate on something that may have evolved.

I'm having problems with a brand new htc amazing. The Wifi connects but only for a while and only at like 1 bar even if I'm right next to my router. My Ipod and other devices can connect just fine. After connecting it'll remain connected for a while then disconnect. Currently I tried it on stock ics 4.0.3, Energy Rom, and Speedy Rom. Is there anything I can do to fix this? I've also searched at the T mobile forums and I've read some about the wifi driver or something causing this.
Any help would be appreciated.

From other post it usually ends up being the router. Cheap router ? Old, Not up to date with firmware? You should go to stock and call it in to HTC. See what they say. They will ask you for the serial number and software number of your device. You may find the serial number in the ‘Settings’ menu under ‘About Phone’. The software information will be under ‘About Phone’ and then ‘Software Information’.
I'd like to know how this turns out since many others have this problem but no solid solution yet I don't see anybody deal with tech support either.

Turned out that HTC amaze does not like my router on wep64 I switched it to WPA aes and the problem went away. Which us kind of weird since every device works just fine in my house with wep64

I have finally found out the real root cause of this it seems it was my iPod interfering with the amaze wifi. Tested it several tines every time I turn it on the WiFi on amaze takes a dive and eventually dissconnects. I really feel like throwing my iPod out the window for all the headache and trouble it caused.

When I try to connect to my home network with my ipod connected to my wifi at the same time my Htc amaze will connect to the wifi but it'll drop to one bar and hold the connection for like 30s. This happens with Stock ics from htc, Speedy Rom, Energy rom. However, once I turn off the wifi on my iPod 4th gen my htc amaze is able to properly connect at full bar without dropping wifi connection.
Phone specs
rom ICS Energy Rom Aug 6th
kernal Htc Stock ics
Bootloader unlocked s on
My router is a cheap one send from telus called Siemens Gigaset SE567.
This might just be a case that only happens to me other people may not have this problem.

Sounds like router tho not ipod. Have you looked into updating the firmware for that router? Maybe if you call them they can replace for a better one.

Hi fellow owners,
I am considering to buy, but I'd prefer to be a cheap and get the 16GB WiFi version. However, it would be nice to be able to use a USB dongle for 3G from time to time. Anybody tried?
Thanks!

Its micro usb port, will have to use adapter, my advice, use your phone as host spot

good advice. I can certainly do this as well as use a 3g wifi router i have. but using the phone's hot spot drains phone's battery and using a router adds to the bulk. that is why I'd like to try a dongle.
Thanks!

I read in the GSMArena review that the XTZ can be tethered to a phone using Bluetooth:
Even if you get a Tablet Z without 3G, you can still use mobile Internet, provided you have a data plan on your droid phone and the Xperia Link installed. The app simplifies the tethering process. It puts a widget on the homescreen that lets you turn tethering on and off.
You might be thinking that you can just use your droid's Wi-Fi hotspot feature to do the same (and you could). The difference here is that Xperia Link uses Bluetooth to share the Internet connection and not Wi-Fi. This should be more power efficient than a Wi-Fi hotspot especially considering you can keep Bluetooth on all the time, which will let tablet and phone hook up automatically once they are close enough (you can't do that with a hotspot as your battery will be dead in a couple of hours).

I haven't been able to try that yet -- my pre-ordered XTZ has yet to ship -- with my Nexus 4 but it could be a solution to Wifi Hotspot battery drain issue.
-- Edit to add --
Well, found the official Sony Xperia Link in the Google Play Store and it's incompatible with non-Xperia phones apparently. Although, the Bluetooth-tether idea still sounds promising. Is there a way to get around the Sony lock-in?
Works!
So I've got the tablet this week and tried just now to stick the USB modem into it.
Naturally you have to be rooted, then you need a dialer :
PPP Widget
from the author of usb_modeswitch (ubiquitous linux tool to change the usb modems from CD to serial mode)
then you need the usb drivers unsurprisingly missing from the stock rom:
On author's forum
then insmod the modules in the zip file:
cdc-acm.ko
usb_wwan.ko
option.ko
(option requires usb_wwan to be loaded first), drop the widget on the home, it should do its magic and ask you for the APN. Then it works.
what a joy.
p.s. apparently the dongle I have needs more power than there is on the tablet port, so you need a powered hub (clumsy) or an external battery and a Y cable to power it.
Hi, newbie here. My GT-P7500 won't connect to PC, red X appear on the battery icon. I tried connecting with a new original USB cable at local store, still the same. Maybe someone knows an advance way to root this device without connecting via USB? I know this is an old device, I should just thinking about getting a newer device, but it's just not my style to dump things knowing it is still usable. So thank you for anything you might suggest to me.
Uhm... The red X should be on the battery icon - USB charging is disabled by default due to the really slow charging time.
So, unless there are other problems, you don't seem to have a USB connection problem at all.

You're being so sophisticated, I couldn't get what you trying to tell me. Could you be a little more simple? What are you trying to tell me? Why the red X should be on the battery icon? Doesn't it indicate that something is wrong?

It should be there on stock ics because USB charging isn't enabled by default on the stock kernel (I think ). About your problem, do you have the correct drivers installed?

Trust me, I wouldn't have created this thread if I hadn't tried all the basics. The only thing I can hope now is a magic to root this device without connecting via USB. :cyclops:

Try connecting it again using different cables. Go ahead and check out if your computer reads it. You can try it on a different computer or just check if MTP Application is enabled and if USB Debugging is enabled under Settings.
