BLE / keyboard

[rmalchow]

i am currently working on implementing a esp32-s2 based dongle that can input OTPs for me. it's a mess. and security-wise, it is really silly. it is more of a proof-of-concept. but these boards are cheaply available, and there is also an entire community of keyboard modders using OSS firmware (zmk / qmk) on pretty capable microcontrollers.

so the question is if it is possible to implement a way to pair a device via BLE, and, if this device is available, have a UI element that simply sends the token to the device, and then have either the esp dongle (acting as a HID device) or the keyboard firmware itself type the code for me.

i know this is pretty vague - but do you have some thoughts?
