Binding Procedure

1. Power the flight controller by connecting USB. Please make sure that the port driver of the flight controller is correctly installed on the computer, then open Betaflight Configurator(Latest version) to connect, enter to the “receiver” interface, and then click “Bind Receiver”, the red LED at the bottom of the flight controller will flash quickly, which means that the SPI ELRS receiver enters the binding mode. There is another way to make the receiver enter the binding mode: after connecting to the Betaflight configurator, move to the CLI interface and enter “bind_rx” in the command line.

2. After correctly connecting the ES24TX or ES24TX Lite/Slim module or DIY 2.4G ELRS TX module to your Opentx radio transmitter, copy the latest version of ELRS.LUA file to the SD card in the remote controller. The directory is “SD Card/Scripts/tools”, Then run ELRS.LUA and upgrade the specified TX firmware through Wifi, and then click “bind” to link with the SPI ExpressLRS receiver. The Red LED will blink slowly, this means the bind is successful. Note: You need to adjust the Packet Rate to 500Hz from the ELRS interface of your radio controller before binding.

3. After the binding is successful, please re-power for the radio transmitter, and then the Red LED at the bottom of the flight controller will getting to be solid, and the telemetry can be received at the same time.

4. The meaning of the LED status of the SPI receiver: the LED is getting to be solid, indicating that the bind is successful or the connection and communication is normal, the LED flashing quickly indicates that the receiver is in binding mode, and the LED flashing slowly indicates that the there is no signal received from the radio controller.

Note: Do not allow the antenna plug to touch the Motor soldering pins, as it may burn the ESC.
