C009 RCU MANUAL 4.3 - IR Programming Operation Sequence a) ATV writes 0x01 to IR_PROG_CONTROL to START an IR programming session. This invalidates any previously started session. b) For each key that ATV wants to program:

1) ATV writes the corresponding key ID to IR_KEY_ID. The key ID is 2 bytes. Keys are identified by Android key codes and are always written in ascending key code order. The remote should ignore any key codes that it does not support. 2) ATV writes the corresponding IR code to IR_CODE . The IR code might be split into multiple consecutive writes. Payloads shall be concatenated in the order of arrival. The resulting byte sequence shall be interpreted according to IR Code Format . c) ATV writes 0x00 to IR_PROG_CONTROL to FINISH the IR programming session. A successful response guarantees that specified keys have been successfully programmed. HID mode. Note: Not specified keys shall operate in the BLE HID mode.
