mbed-ble-hid VS esp32_mouse_keyboard

https://github.com/tcoppex/mbed-ble-hid/blob/master/src/services/HIDGamepadService.cpp , the hid_report_map descriptor needs to be modified. The original input report needs to have a report ID, and then a new section needs to be added as a output or feature report, with its own report ID. This is a bit of a mess to research because there's no real standardization. PlayStation controllers have their own format, Xbox has a different one.

Yes it can, but I'm leaning more to make it wireless (if it does have ton of latency). For the USB host thing I'm thinking to use https://github.com/asterics/esp32_mouse_keyboard but it don't understand the piece of code 100%, looking more into it. If there is any suggestions or criticism I'm open for it, Thank you

You will find very little esp-idf based resources, outside of the espressif documentation. If you dive in, you might be able to get it. I’ve been trying to figure out how to get a proS3 board to be used as the controller for a Bluetooth keyboard. Your hill is steep. But it can be done MK32 aaaaaand that’s the end of esp-idf related links, in case anyone gets annoyed by links that are not esp-idf, be forewarned the next links are just that. hackaday asterics t-vK best of luck, I truly hope you figure it out and leave breadcrumbs for the rest of us. Or sell your esp s2 board for the big bucks.
