2.2.7 Stuck Key time out function
Stuck Key means that a key has been pressed for a very long time in normal operating mode.
To preserve battery power, the remote will shut down after 25-30 seconds after the last key
transition to consume minimal power. After all keys are released, the remote resumes normal
operation.
The following diagram shows the time limit when the stuck key power down mode is entered.

STUCK KEY TIMEOUT
* Stuck Key Timeout is typical 30 seconds, actual timing depends on the protocol transmitted
Power down -mode
Note: For some protocols in database, the stuck key timeout ranges from 15s to 70s.
2.2.8 Simultaneous Keypress
If more than one key press is detected, remote controller will stop sending IR code.
2.2.9 Standby mode
The standby mode of the remote shall be entered approximately 5 seconds after the last key
is released.
2.3 Real time requirements
There will be data transmit latency on both Bluetooth interface and GPIO interface, compare
the timing, the BT latency is much heavy, around 100ms (maximum).
