Unable to use gamepad features for Adafruit Feather nrf52832 #723

Open jeff-j-chen opened 2 years ago

jeff-j-chen commented 2 years ago

Operating System

Linux

IDE version

1.18.19

Board

Adafruit Feather nrf52832

BSP version

Github latest

Sketch

https://github.com/adafruit/Adafruit_nRF52_Arduino/blob/master/libraries/Bluefruit52Lib/examples/Peripheral/blehid_gamepad/blehid_gamepad.ino

What happened ?

I am able to successfully connect over Bluetooth to my board, however, it is classified as type "Unknown" and none of the gamepad features, like the joystick or buttons, register. The same code works fine on Windows.

How to reproduce ?

  1. Upload basic starter code to board
  2. Connect board via bluetooth to computer
  3. The device is initially recognized as a gamepad, but changes to Unknown, and none of the inputs work.

Debug Log

I suspect it is something to do with a faulty device descriptor. See below:

can you post the log from the nrf52 side with debug level = 2

thanks for the log, I don't see any issue on device side. Could do you detail on your linux machine (distro and version) and how do you test the gamepad. Last time I tried, it works just fine with ubuntu 20.04 using an app called 'antmicro' 'antimicro'

Testing was done with an application called jstest-gtk, which recognizes my Xbox and Playstation controllers without issue but fails to see my custom gamepad. It is the same story with a website called gamepad-tester. I also tested it on one of my Steam games (Crawl) and it doesn't work there either. I can't seem to find the antmicro you're talking about, could you provide a link?

just tested again, and the gamepad able to send buttons just fine with antimicro (mispelled in previous post). In screenshot, it is sending button5, antimicro is small gamepad test I found in ubuntu software store for testing

my terminal output has less error than yours, kernel does complain a missing GAP attribute, but it does not affect the functionality at all. Follow is my uname and bluez version, maybe update your software if older. Let me know if you want to have any extra info for troubleshooting.

I actually have a later version of bluez, see here: 

jeff@pop-os:~$ apt list bluez

bluez/impish-security,impish-updates,now 5.60-0ubuntu2.2 amd64 [installed]
bluez/impish-security,impish-updates 5.60-0ubuntu2.2 i386

Can you check that it still works on bluez 5.60? Bluez is tied to the Pop-desktop so I can't easily downgrade it, and I'd prefer not to mess with my kernel since doing so in the past has broken things like my wifi and graphics. Please check on your end that the gamepad still properly registers with bluez=5.60

hathach commented 2 years ago

Unfortunately, I wouldn't want to upgrade my bluez stack either, especially the next LTS is about to dropped (I may go with Fedora 36 though). I will test again with the new OS later on. Meanwhile, maybe you could try to install 'AntiMicro' to test.
