I made a discovery today. The cable which is used for e.g. sending apps between two TI-84 calculators does actually fit in the USB socket of my HTC Hero
When I connect the Hero to the TI-84 the Hero's little LED turns green for a second and the TI-84 actually boots. If I let the Hero be in sleep mode and I press the ON button on the calculator the Hero wakes up
I have found a document which describes parts of the TI-84 USB protocol here.
It would be really awesome to be able to communicate with the TI-84 from Android apps on the phone. I have never programmed an app which uses the USB before, but I know there is an API for doing it.
Can this be achieved in accessory mode or is host mode required? AFAIK the accessory mode requires the accessory (TI-84) to be using a special Android accessory USB protocol to work. Can someone confirm this?
Is any developer interested in this?

Hey everyone,
Been searching around for a decent Android head unit and stumbled upon these:

I'm interested in a single DIN unit so that the screen can be hidden away when I don't need it. Primary function would be to interface with my Megasquirt ECU and display necessary gauges for me via MSDroid or Shadow Dash.
Those above examples have dual core 1GHz A10 CPUs with 1GB RAM, running Android 4.0. Not too bad.
Does anyone have experience with these particular models? Or any other recommendations.
Something discrete or able to be easily tucked away is important, I have a very minimalist interior and would like to keep it that way.
Trying to find out if it has USB OTG or USB Host, planning to use a USB to Serial RS232 converter. I contacted TradeSolution and they said the head units don't support USB OTG or Host.
I know the units above use WiFi/3G USB dongles, and you can plug a USB hard drive to it. Doesn't that mean it does have OTG/Host functions?
Okay so I know with Bluetooth and can be a LARGE variety of issues going on with connection. But I do not believe it is <Connection> problems that I'm talking about/having issues with.
Anyways, I have a Qualcomm Atheros AR3011 Bluetooth 3.0 dongle in the back of my computer.
When I go to pair my phone to the computer, it works perfectly. (See screenshot below...)

So as you can see, it is paired, and in Device Manager it shows, along with the adapter, and my S160 headset (Which is disconnected.)
Now my problem being is when I go to Devices and Printers in Control Panel, I see my phone (SCH-i650) But all I see are these options when right clicked...
Now I know my adapter supports Music Streaming, AND headset support etc. etc. because it worked back in Windows 7... Is there any way of getting this support back??? And/Or does anyone know perhaps as to why I am not getting the options for listening to phones audio etc...?
And would anyone be willing to help me figure this out/trouble shoot it? I have no idea where to start.
I would also like to know if it's due to my phone or not.
This is kind of like the options that I would like to see:
On another note, I just tried using the "Send file/Receive file" options, which work perfectly fine... So where is the listen to audio and make phone call options?
So, I purchased this neat dash cam/backup cam/GPS Android-powered rear view mirror from eBay and received it today. I've been playing around with it a bit and I'm curious first off, if anyone on XDA happens to have it. I'm curious if anything has been done to it yet.
I have an issue signing into an account with it, Google Account Manager crashes when I try creating a new account and it doesn't connect to the server when I try logging into an existing account. I tried all the normal fixes (clear cache, etc) with no success. I have internet access though because I'm able to use browser and navigation. Also, the speech is super annoying. It's in "English" but it's a super strong Chinese accent and I can't change it or download any other voice options.
If anyone is curious for more information on it, let me know and I'll provide what I can. I want to toy around with it a bit and I'm hoping someone has already done so. I also need to fix the issues I'm having and I'm not sure where to begin. I've been out of the development game since GS3.

Could someone try hooking up the charger to their PC when in recovery? I'm wondering if that would connect it to the PC or if you are going to have to go through a more complicated route...I'm thinking through the charger won't work.
To access fastboot you swipe from top left to bottom right in a straight line when booting. Do this when the Wear24 words are on the screen. If it doesn't go into it, then try again. I was able to do it at a store.
Instructions from verizon:

The charging base does not contain the circuitry for data.
If you take a look at the fcc filing photo, it only has two wires for charging.

There must be a way in using WiFi or bluetooth. I'm suspecting WiFi

Fastboot doesnt work over WiFi, only over USB.
Besides, does Qi even support data?
I think the only way is to crack the watch open, and map the pin points to a male usb cable. Someone on another thread was attempting it.
I will just leave it here: https://forum.xda-developers.com/an...how-to-install-twrp-recovery-achieve-t3781502
Hello! OTG works fine with the Y cable, but the phone refuses to charge whatever i do. Is there a way to activate the charging while in host mode?
This is the kind of cable i'm using.

I think it would be a way to upload a modified kernel, that would allow this, but i have no experience with compiling kernels. Is there something already available for the Redmi 5 Plus?
Thank you!
I managed to get it working. This is how, maybe it will help somebody.
1. First you have to unlock your bootloader.
2. Then install a custom recovery, i went with OrangeFox
3. After that i installed LineageOS 18.
After the ROM instalation everything works perfectly. I now have OTG and the phone is charging at the same time.
I needed this old phone to run OctoPrint for my 3D printer, instead of buying a rasberry PI 4, which is expensive at the moment and lower spec than the Redmi 5 Plus. So this is a huge win, as i already had the phone and it was collecting dust. Until now.
