KEY_POWER
Thanks. Works on an android phone. Turns it on and off. On android TV only turns it off but does not turn it on. Smart TV XIAOMI Mi TV 4S 55. Maybe you need to KEYCODE_TV_POWER?
I don't know if this is even possible. This is a very device-specific problem. You have to figure this out yourself. Try different codes in the media keys section of the _hidReportDescriptor. You saw an example in #74 .
Here is a list of possible codes:

If you want to use a code bigger than 0xFF, then you have to split it. i.e. for AL Calculator (0x192), you split it into 0x92 and 0x01: https://github.com/T-vK/ESP32-BLE-Keyboard/blob/928c09320e3e6e344a63640c7de21d52a20c1d47/BleKeyboard.cpp#L81
public static final int KEYCODE_TV_POWER Added in API level 11 Key code constant: TV power key. On TV remotes, toggles the power on a television screen.
Constant Value: 177 (0x000000b1)
Once the TV is turned off, BLE disconnects from the TV. Can we send bt packets still while unconnected state?
