ESP32-BLE-Gamepad VS bluepad32

Trying to find premade code to make an xbox style controller for Steam. I have looked into it before but what I found isn't exactly clear. https://github.com/lemmingDev/ESP32-BLE-Gamepad This was the code I found but I don't understand what they define as a "hat" and how you're supposed to get 128 buttons.

Conveniently, I had a spare ESP32 board sitting in a drawer (which is not an Arduino and technically makes the title of this post innacurate, I know), and a quick Google search showed that some legendary human being had already done the hard work of writting an Arduino library to create Bluetooth wireless gamepads on ESP32. The stage was set!

Absolutely! It's quite a bit more complicated, but someone else has already put their code on GitHub for one: https://github.com/lemmingDev/ESP32-BLE-Gamepad

I simply want the controller to be able to function as a single full-fledged controller (with all the buttons of a regular controller) but also have the functionality of being split into two smaller/simpler controllers. For a smaller handheld, I was able to create a simple bluetooth controller using an ESP32-WROOM-32 and the ESP32-BLE-Gamepad library by lemmingDev.

Googling ESP32 Bluetooth game pad shows that there are libraries so I assume it's possible.

I used the ESP32-BLE-Gamepad library and changed up the flight controller example code slightly. I’d appreciate any advice, thanks!

Yes, with an ESP32 and the Bluetooth LE Gamepad library.

This is the library I used.

Have you looked at this one? https://github.com/lemmingDev/ESP32-BLE-Gamepad

and more (See complete list here: https://gitlab.com/ricardoquesada/bluepad32/-/blob/main/docs/supported_gamepads.md )

Ah I see! The "Gamepad" example does that. You can copy paste the few functions and setup lines into your code and in your loop put a time variable if clause in there that executes every 10ms or so and do the update() etc stuff. And with that you can query the inputs and do stuff with it. Difficult part for me was to flash on the Nina coprocessor: https://gitlab.com/ricardoquesada/bluepad32/-/blob/main/docs/plat_nina.md

I'm trying to use an 8BitDo with my Arduino based project but I can't find a good starting point. So far I've found ESP32-BLE-Gamepad which enables an ESP32 to emulate a gamepad but not connect to one and bluepad32 which supports the controller but is based on esp-idf.

I’m trying to connect a BT gamepad to an ESP32, and it seems that Bluepad32 would do exactly that.
