Connection Behaviors
Once a remote and STB are paired, the BLE connection will be kept maintained (using the connection
parameters shown in the table - section 2.5.1).
If the connection is terminated, the RCU will enter deep sleep.
Note
If connection fails to be established, the RCU will directly enter deep sleep. If the RCU is already
bonded, upon key press, it will send directed adv packets for 2s after wakeup from deep sleep; if it fails
to be re-connected during this 2s duration, it starts to send general adv packets. The RCU will enter
deep sleep if adv time reaches the “10s” timeout duration.
The timeout has a deviation of 1~3ms (when Power Management is disabled)/up to 10ms (when Power
Management is enabled).
If no connection has been established after RECONNECT_ADV_DURATION, the RCU will go to deep
sleep and then wake up upon user input is detected. The key value of the detected pressed key is sent via
IR, and after connection is established, the key value of any pressed key will be sent via BLE instead.
