Battery level check
(*1)Prevent key ignore during the pairing or reconnect process.
( If key events occur the RCU must send the key code )
IR operation period
[BLE connected status]
-
Transmit the code by BLE
[BLE disconnected status]
-
Transmit the code by IR
[Note]
-
If key events occur the RCU must send the key code(*1)
[Operation]
-
Press and hold [RED] and [BLUE] key for 5 seconds
[When Forced IR]
[Google Assistant] : BLE send
other Buttons : IR send
[LED behavior]
-
LED keep to light up fast blink 9 times when converting completion
[BLE recovery]
-
Method1: [RED] and [BLUE] key for 5 seconds
Method2: Battery reset
Method3: Unpairing
If the RCU is in a low power state, it will shut down directly without
warning (warning=LED blink).
V_shutdown = 1.9V
V_recovery = 2.3V
-
The voltage is checked once every 8 seconds for 30 seconds after
the button is pressed.
-
If the button is pressed again within 30 seconds, the time is
extended by 30 seconds.
-
For the rest of the time, the voltage is checked once an hour.
-
The value of remaining voltage is kept at the lowest value.
-
If the lowest value is updated, it will be sent to the TV side.
-
Voltage detection is not done while the button is pressed or when
IR is transmitted.
-
The remaining voltage will be initialized under the following
conditions.
(1) When the battery is removed or inserted (Hardware reset)
(2) After pairing.
(3) When the status is changed from deep sleep to wake.
Pairing or Reconnecting process term
If a key event occurs at this term,
the key code transmits by IR so that the
key event ignore can pravent.
