韋恩的飛行筆記

Bind 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 bind mode. There is another way to make the receiver enter the bind 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 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 firmware to latest version and click “bind” with the SPI ELRS receiver. Please make sure the packet rate is the same between the SPI ELRS Receiver and your ELRS TX module.

Change packet rate for the SPI Receiver command in the CLI tab

Set expresslrs_rate_index = 3
Allowed range: 0 – 4
Default value: 0
0=500Hz,1=250Hz,2=150Hz,3=50Hz,4=25Hz

3. After the binding is successful, 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.
