[Q] Bluetooth tethering w/o root between android phones - General Questions and Answers

Hello everybody,
I'm trying to develop an Android application in order to enable bluetooth tethering between two android phones without the need of root permissions.
I found in the market PdaNet as example..
How is it possible to create such an application?
Are there some API already present?
Thanks in advance

Hi,
I'm not really sure that there's an API for that, but based on the much discussion about bluetooth tethering between two android devices, I suppose the answer is no.
if you get to a beta test fase (even alpha), count me in.
I have:
- Samsung Galaxy TAB 7.0 plus (GT-P6210) with original 3.2 kernel;
- LG Optimus One (P500H) with official 2.3.3 version.
both are rooted, by the way.

[Q] ZenithinkZT180 Android 2.1

Hi,
I've recently purchased the above however it doesn't seem to support a usb dongle. Is there additional software to support or modify the settings, plus I can't download apps from the android market or the apps crash everytime I try to install . I heard that a firmware upgrade is available but not sure where to get this from.
Any advice would be useful

It should support this device - it has Bluetooth 4.0 with LE and you can find Android 4.3 firmwares.
I don't have sony z - so ask people in your device thread to be 100% sure.

Hi,
works perfectly with a rooted Galaxy S4, thank you!
Great, it works on my Nexus 7 running CM!
Not working on my Galaxy Nexus though, running stock. Do I need to switch to Cyanogenmod for proper BTLE support with that device?

Please read bold red text in 1 post - Android 4.3 minimum required. Also visit thread for your device with BTLE Drivers.

Well the device is running 4.3, but I guess Google disabled BTLE on the Galaxy Nexus for some reason. BTLE works in CM, and I only recently switched back to stock, so I didn't know it was missing.
The needed modifications to stock GNex are on this thread if anybody else encounters this situation:

I see I'm sorry I thought you have 'toro' or 'toroplus' - they don't have stock 4.3 like 'maguro'

I should have been more specific! Fitbit sync seems to work fine for me now that I have applied the modifications to re-enable BTLE, thank you for posting this apk
Thanks a lot dimfish, it's work for me on my s3 with slimbean 4.3. :good:
Awesome work!
Thanks dimfish, this is fantastic!
What does this mean for BLE functionality with other apps, Endomondo for example? Is this a possibility?
Thank you for this app... Just replaced the one already installed and I can now sync with my phone...

Since you've made this modification, maybe you'll be able to enlighten me to the situation with 4.3 and Bluetooth Low Energy.
Did google push out the BLE spec in such a way that we theoretically shouldn't have to have a hacked app to sync with BLE devices on any 4.3 device, or is it far more complicated in that each device must be custom tailored in the code of the application to sync properly?
If the former is true, I can't really wrap my head around why the Galaxy S4 GPe 4.3 device would have syncing working perfectly with the stock fitbit app, but not the HTC One running a GPe 4.3 rom.
If the latter is true, google didn't fix anything with regards to BLE.

Actually I didn't read Google specs, however I don't see any reason why Fitbit should lie about 48 hours problem described here
So trying to avoid this problem they hardcoded supported devices (so you were able to fool it with modified build.prop).
But lets be realistic - this problem right now affects only Fitbit trackers, while android is still working and bluetooth is working - and when Google decide to help fix this specific problem - who knows...
You sir, are my hero! thanks man
Just tried this on my Sprint HTC Evo 4G LTE running CM10.2 (2013-10-11 nightly). I can confirm that it works perfectly with my Fitbit One! Thanks dimfish!
Working on Motorola Atrix HD
Sent from my Atrix HD using ProBAM rom and XDA 4 Premium
A few questions, pardon my n00bness:
-Does my HTC One have to be rooted for this to work?
-Does this modified apk modify my build.prop file?
-If so, does the app reverse this change once uninstalled?
Thanks!
I love you.
Working great on my cm10.2 for sg3

Downgrade A7 (A750GN)

3 years ago somebody downgraded somebody I met at the internet successful my Samsung J5 to Android 5.
Now I think about the possibility to downgrade my Samsung A7 (A750GN) to Android 4.
Would it be possible?
In know with such a questions a lot of people want to know why.
It's simple.
I love how 4 looks.
I could still enjoy 5 if I have too.
And Android is gone the same negative way like Microsoft with Windows 10.
Every new Android Version has more and more rubbish included I don't use and I don't want,
Today is (for me) my Android Version a overloaded fat elephant with so many bad functions I can't turn off.
I would like to have a "Android Lite" and I would like to have a Android that looks like 4 or 5.
But would it be possible?
I have never ever done something like this for myself.
That last time with my J5 somebody installed a remote control on my laptop and I plugged in my mobile and this guy has done everything remote controlled.
I have still to today no idea who he was and from where he was.
But it worked fine.
He downgraded my J5 to Android 5 and he changed something in such a way the mobile never ask for a update and when I try to force a update I get the wrong answer the newest update in installed.
Absolute great.
That is what I'm looking for with my A7.
Any ideas?
It is NOT possible to downgrade your A7 to android 5.
When a new phone comes out , for example the A7 2018 , it was launched with android 8.
It can not be downgraded to any version below the version it came out with.
Even after updating from android 8 to the latest android 10 , i don't think it is possible to even downgrade to android 8 again (because samsung updates, patch your phone with the new update.)
Galaxy J5 was released with android 5 touchwiz, the android 5 system customized by Samsung.
The person who was connected to your computer has installed a custom rom (probably an AOSP rom , as you described being a "lite version".)
AOSP roms are roms without the Samsung add-ons and customizations , created by developers here on XDA.
For the moment , an AOSP android 10 for A7 2018 is not available , but there is another way to get a "lite " version of android 10 on your device.
As it needs a lot of reading and understanding on android development, i do not sugges you doing so .
It is called GSI and you can find by reading in the correct thread , for example :
https://forum.xda-developers.com/galaxy-a7/help/how-to-install-gsi-samsung-galaxy-a7-t4165617
Please , be aware that you might brick your device if you decide to experiment with its system.
Hope this helps you.
