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: (For a complete list refer to the HID Usage Tables document at usb.org (Section 15. Consumer Page (0x0C))

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)

evg26 commented 3 years ago

Constant Value: 177 (0x000000b1) - how to record?

velechit commented 2 years ago

Once the TV is turned off, BLE disconnects from the TV. Can we send bt packets still while unconnected state?

velechit commented 2 years ago

Isn't key code 177 (0xB1) already assigned to (Pause)?
