OTA
To support OTA, install the apk “VoiceBLEOTA_1.2.1” on the android mobile phone and then pair the RCU with the mobile phone. Complete OTA upgrade according to instructions.
Otherwise, if the far unit integrates the OTA codes, the RCU can be upgraded via Bluetooth.
Low voltage indication
- When the battery voltage is lower than 2.4v, a low voltage indication code (OxAE) will be transmitted following each pressed key(RC should send the key code firstly). Also, the red LED indicator will flash for S times (f=1Hz, duty=0.1.
- Once the battery is OK (>2.4V), the RCU will stop sending the battery low code after each pressed key.
