BLE HiD Keyboard on Windows 10

Does anyone have a working solution for BLE HiD Keyboard on Windows 10.

I could not make the WIP one to work:
https://github.com/micropython/micropython/pull/6559

I would like to send just a simple character and see it written in some editor.

Thank you!

Re: Cannot find I2C devices on ESP32

This simplifies things, I just used 4.3K Ohm resistors and can confirm that everything works fine.

Thanks again!

Thank you Roberthh!
Your pullup idea did the trick:

One can see that the green wire is SDA.

NB: I did try to switch the wires on esp32 and got the same result

Hello, I am trying to make a display (128x32 I2C Pi OLED) to work with esp32 (ESP - WROOM-32) OLED device is working properly as I have tested it with Arduino using Adafruit's libraries. Esp32 device is working properly as it runs other code without problem. I followed a video [https://www.youtube.c...

invalid trigger behavior

Hello, I have some interrupt trigger testing code which doesn't work properly: from machine import Pin from time import sleep interrupt_pin = None def handle_interrupt(pin): global interrupt_pin interrupt_pin = pin pin = Pin(12, mode=Pin.IN, pull=Pin.PULL_UP) pin.irq(trigger=Pin.IRQ_FALLING, handler...
