and automatically reconnect with the dongle. After successful reconnection, the RCU will stop transmitting
IR code.
Remove the dongle, or power off the dongle. Press any key and not release it, after wakeup from deep sleep
the RCU will send directed advertising packets for 2s and then in-directed advertising packets for 10s.
After 12s expires, the RCU enters couch mode. Release the key in couch mode, the RCU will send directed
advertising packets for 2s and in-directed advertising packets for 10s, and then enter deep sleep.

The remote shall un-pair and clear its pairing table when the "Down" button and the "OK" button are
pressed for 5 seconds or more. The red LEDs of the RC will blink three times at the rate of 125ms on and
125ms off.
When entering un-pairing mode, if in connection state, first terminate the connection, disable advertising,
and check whether there's pairing information. If yes, delete the pairing info.
The white LED of the dongle will be turned on to indicate un-pairing success.

2.4.3 BLE - IR Switch

After each power on, the RCU will enter IR mode by default.
In order to reduce power consumption when RCU is in IR mode but unconnected BLE state, RCU goes into
suspend mode in every 500ms, it will further go into deepsleep after 60s. When an IR key is released, RCU
would similarly go into suspend mode in every 500ms, and further go into deepsleep after 60s.
After connection is established, the RCU will enter BLE mode. The red LED of the dongle will be always
on to indicate BLE mode.
Whenever in non-connection state, the RCU is in IR mode.

2.5 Connected State
