It is strange that the Dmitry has not yet made this correction. After all, without it, media buttons do not work at all. :roll_eyes:

I am a little lost, so this allows me to use an ESP for as virtual Bluetooth keyboard for devices? (Similar to how the Logitech remotes did?)

Also, can I switch between multiple devices, or would I need a separate ESP for each one? I have a Shield, Android TV and PC for example, can I switch between each device?

I’ve run out of ESPs, so working out how many more I need to order
Thanks :slight_smile:

Hi,
I am having the following problem:
After the ipad connects to the esp32 bluetooth, every time I restart the esp32, the ipad cannot automatically reconnect to the esp32 via bluetooth. On Android phones I don’t have this problem. Currently I have not found out the cause of the problem

How to install this?

This is cool for sure and much appreciated. Maybe its just me and a lack of imagination but, im struggling to think of any reasons to need a keyboard. Sure, you can find a use for controlling the volume on something or a few keys to toggle this or that but a full size keyboard seems overkill for those things. What am i missing or not thinking of here?

I’m having this same compile problem with EspHome 2024.3.0

Any ideas?

@Tomsdad did you ever resolve this? I am trying to use this and am getting the same error unfortunately…

I never did. I fell back to the old solution that I had that uses this: https://github.com/clubcotton/esphome/blob/main/playground/esp32_ble_keyboard.h
