Overview

This product contains 17 function buttons. The plastic shell is used as the outer frame of the product, which improves the appearance and feel of the product. The buttons are designed with a metal dome so that the life of the keys can reach 1 million times. There are two LEDs (Blue & Red ) to show the RC modes.

Also, two are backlighted keys: the MUTE key is red, and the TEAMS key is blue(The button screen is transparent and the blue and red LED lights are below the button).
2*AAA battery as the power supply. The product supports the OTA function.

LED indicating status

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

1. 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.
2. Once the battery is OK (>2.4V), the RCU will stop sending the battery low code after each pressed key.

The remote control will send the code value after pressing the button, and the code value of Ox00 will be sent after release. Far Unit is required to determine whether it is short press or long press according to the time it receives the key value of Ox00

 IR code

Only the power key should send the IR code. For this version of RCU, the IR LED is only hardware preparation for future SW support.

Keep-alive

2.6.1 After pairing is complete, the RCU will transmit every second a keep-alive signal (code) to the far unit.
2.6.2 when RC disconnected with the host(RC still have pairing information), RC should send reconnection ADV per 10 seconds, last for 500ms
