• Kit version (for WroverKit/PicoKit/DevKitC): v2
• Core (if using chip or module): ESP-WROOM32
• IDF version: Unknown (arduino-espressif32 @ 9570b77)
• Development Env: VSCode with PlatformIO

Problem Description

I'm trying to connect to a Xbox One S gamepad using bluetooth. Since the gamepad uses classic bluetooth I can not use the (very good) BLE library available for arduino, neither use the BLE examples as a reference.

I used the discovery example as a reference and can now discover the HID service offered by the gamepad - but I could not figure out how to actually connect to the discovered gamepad because I could not find an example for this case.

Is the functionality for BTC HID already implemented and/or are there any examples on how to communicate with such a device?

Thanks,
Denis

Hi @Lunatix89 Sorry to tell you that, we haven’t implemented this feature yet.

[Lunatix89]

Okay, but that's good to know.
Any chance that this will be implemented in the future?

[blueMoodBHD]

At present, we do not have this plan yet.
I will inform you if we have plans to begin.
Thanks.

Is there any other problems?

@Lunatix89 did you find out how to do it? I'm trying to do more or less the same thing.

@blueMoodBHD
I might be able to find out how to do the HID thing myself, but I would need a sample that shows to to interact with l2cap. Any link? Thanks!

yes. I'm not using bluedroid from esp-idf. Instead I'm using btstack: https://github.com/bluekitchen/btstack/
which supports BT Classic + HID. It is a commercial project, but free for open source.

And I implemented support for gamepads (Xbox One included) in this project:

(which is open source, feel free to reuse the code, but you have to comply with BlueKitchen license)

Thank @ricardoquesada for following up. I currently use my labtop open javascript html5 webpage to send my controller keystroke to ESP32 web server. It for my personal use. Thanks, your method is better than mine. I will try.
