Possible to read state of capslock key using KeyboardBT?

[itrr0]

I'm porting a project from the mbed os core for rp2040 to the arduino-pico core since it has a bluetooth keyboard library and I'm wondering if it is possible to see if the capslock key is activated or disabled on the connected bluetooth device.

Ooops, mybad. I completely zoned out and forgot we already support it. The onLED callback works in USB and in Bluetooth mode. See the KeyboardBT example. You can't "read" the state, but you get a callback whenever the state changes, so just keep track of it there. In the example it sets the Pico's LED on or off for CAPSLOCK.

Thank you so much, I thought that function only kept track of capslock presses sent from the microcontroller but it appears that I was wrong.👍
