Stadia controller with Bluetooth LE not recognized

[kentyman23]

Describe the bug

I updated my old Stadia controller to use Bluetooth LE instead of Wi-Fi, but it doesn't work with Moonlight on my LG C2. For the record, it works great with the native GeForce Now app, so I know it can work on this TV.

To Reproduce

Steps to reproduce the behavior:

1. Ensure your Stadia controller is updated to work with Bluetooth LE: https://stadia.google.com/controller/
2. Pair it with your TV under Devices
3. Optional: Ensure it works well with GeForce Now app
4. Try to use with Moonlight but confirm that no button does anything
5. In Steam settings through Moonlight under Controllers, notice that it doesn't show any connected controllers

Expected behavior

It should work just as well as my other Bluetooth controllers

Basic information

• Moonlight version: 1.5.3
• Model: LC C2 OLED55C2PUA
• webOS version: 7.3.0
• Firmware: 03.30.16

Additional context

For the record, I got my Xbox controller working by downgrading to not use Bluetooth LE. That said, this controller works fine with GeForce Now, so presumably can be made to work with Moonlight.

Hi, maybe the controller was not mapped yet. webosbrew/apps-repo#77 I'll develop this app later for you to test the controller.

I'd also like this to work

I bought a Stadia controller and switched it to Bluetooth mode. And it turns out at least on my webOS 5 TV, input events can't get picked up at all. Not in moonlight, nor GeForce Now. Reading raw data from the OS won't produce anything either.

I tried a few gamepads and here is the result:

• Xbox One Controller: Working, mapping is correct
• Switch Pro Controller: Working except for snapshot button. Home = Guide button
• Stadia Controller: Can be paired, recognized by moonlight, but not producing any input event.
• Xbox Series Controller: Can't be paired at all

Although this can be varied between different TV models, I think Stadia Controller via Bluetooth can't work on some webOS TVs at all. One possible reason is it has newer BLE version for the TV to handle.

Please let me know if it has different situation on your TV, be sure to provide your TV model and webOS version.

On my C1 I can't pair the stadia controller at all, it won't show up in the Bluetooth pair menu

It definitely works with my TV! Now, it is true that this controller is glitchy on many devices such that you have to unpair/repair sometimes, but I use it with GeForce Now on my C2. From original post:

Moonlight version: 1.5.3
Model: LC C2 OLED55C2PUA
webOS version: 7.3.0
Firmware: 03.30.16

Can you try unpairing and re-pairing with GeForce Now? It definitely works for me.
