It is strange that the Dmitry has not yet made this correction. After all, without it, media buttons do not work at all. 
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 
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
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
I had the same issue. Managed to resolve the compilation by setting use_default_libs to false.
In the example provided in the documentation, in the last line, replace true with false.

Your change helped it get further, but now I get a new error:

Any ideas?
Did you replace or download the external component? For me it works like this (replace the substitutions with your own :)):
