Is it possible to make a WiFi or BT HID device? (Without Dongle)

Would it be possible to create a wireless device that behaves like a mouse or keyboard when connected wirelessly to a computer?
I know it would be possible using a USB dongle, that can be recognised as an HID device, but would it be possible for a completely wireless device to be recognised as an HID device (mouse/keyboard) once it connects via Wifi (or at least Bluetooth, if not possible with WiFi)?

Espressif has an example for an HID mouse in the IDF

Thank you for your answer,

As far as I understand, this solution is for the software on the side of the host.

What I'm looking for is a solution for the firmware of my ESP32, since my project has no host software.

Cheers!

whuch ESP32 are you using? does it have a USB OTG port? e.g. have a look at the ESP32-S3-DevKitC-1 which in addition to the USB-to-UART bridge has a full-speed USB OTG interface

Hello there,

I believe this OTG is for cabled USB connection. I'm looking for a wireless option. :slight_smile:

Thank you!
