Update BLE Joystick

[Pmant]

This PR aims to fix #1563 and does further improvements to the BLE Joystick.

Android does not understand simulation controls like rudder or throttle.
To achieve a higher compatibility a generic gamepad with 8 axis and 16 buttons is used instead of simulation controls.

CRSF Channel mapping:

• first 8 CRSF channels are mapped to axis 1-8 in this order: x, y, rx, ry, z, rz, slider1, slider2
• remaining 8 channels are mapped to buttons 1-8
• the user can modify the model's outputs to remap channels
• 3 way switches can be mapped to an axis to receive a meaningful output

The PR also removes the 100Hz update rate limit and instead uses the Packet Rate set by the user.
I have tested this on a Windows PC with Packet Rate F1000 and did not drop packages. However it's up to the user to change the Packet Rate if it does not run well with less powerful receivers.

tested on my oneplus 7t with android 11 in currykitten sim and freerider recharged - working fine.
also tested on my ideapad 330 (ubuntu 22.04.1) with freerider (recharged) and also working fine.
good work!

While in Bluetooth joystick mode, the Lua script crashes. Maybe somebody could create a little joystick bitmap for the OLED screen?!
And change the Lua script to give hint, that this mode is running and the sx12xx chip is in deep sleep - joystick mode.

Tested on Mac with Tryp, Liftoff and FPV.SkyDive. Lua script does not crash for me.

Which ExpressLRS version is this, when running this branch now? Is it 3.2.0 or way earlier?

This PR is based off the current master branch, which has all the features of 3.2.0.

so i've to add my hardware: jumper t-lite (v1) will test with v2 later

Personally I've tested it on the v2 without problems for ~30 minutes on all packet rates. Which packet rate were you using?

I tried using it in my Poco X3 Pro with Miui 13.0.3, and it didn't work in FPV.SkyDive and in freerider demo.
Also tried with a random game (Descenders) and it didn't work either. :(

I tried sky.dive on iPhone - didn't work, but didn't work with any Bluetooth controller on any simulator on iPhone. On Android, fpv freerider (inkl recharged) and CurryKitten Simulator works fine.
Sky.dive didn't work, only with cable - I don't like it anyway.

Tested again:
sky.dive did work on my oneplus 7t (Android 11) —still don't like it anyway.

tx16s mk2 elrs, tried this and fails, no reaction on android and even pc, my elrs version become head ism2g4 a08732

Did you do anything on you phone for it to work?

iPhone only allows accredited bluetooth HID devices to attach to them. So it will never work on an iPhone.

[nightflasher]

Did you do anything on you phone for it to work?

No, just connected via Bluetooth and it works. Works on all modules and t-lite v2 with Ubuntu 22.04 (fpv freerider inkl recharged and steam), as well as all the sims on my android.
Sky.dive was a bit odd (arming via touchscreen) - but that's why I don't like it.

[Pmant]

At this point it is hard to tell whether the reported issues are caused by this implementation or the inability of the receiving device and software to work with any BLE gaming device. Can anyone confirm it not working whilst working with another BLE controller?

for d113a5, tx16s mk2 elrs can now finally work on android 12, tried skydive and rds , no problem, and really thanks all of you.

Hi,
I am very interested in this update, mainly for the Android support (#1563), thank you !
Do you know if this will be included in the next release ? And when ?

This PR is merged already and will be released with version 3.3. You can test it now if you select the master branch as the firmware version in ExpressLRS Configurator.

Thank you for your answer, I will definitely give a try !

My tx16s mk2 worked fine with ble joystick on velocidrone. I updated to 3.3.0 now my windows 10 laptop recognizes and connects to the tx Bluetooth but in the sim nothing. Any known fixes for this?
