SBUS Use Case

Drone Use Case

This chapter provides an SBUS communication example to help customers understand and use the SBUS communication function of LQ modules.

• Connect the receiver to the AP unit of the LQ-10 module. Connect the STA unit of the LQ-10 module to the flight controller's SBUS interface, and configure them for SBUS transmission and reception, respectively.

After receiving the devices, first connect the receiver to the AP unit of the LQ-10 module as shown below:

On the AP unit, connect UART0 RX to Sbus-Tx on the receiver shown in the figure, and connect GND to GND. On the STA unit, connect UART0 TX to Sbus on the flight controller shown in the figure, and connect GND to GND.

• Click to enable serial port UART0
• Select SBUS as the function mode
• Add a forwarding rule. Select UDP as the transmission protocol, Unicast as the operating mode, Remote as the endpoint, and Transmit as the data direction. Set the target peer to 192.168.1.3 and the network port to 8080 (set the SBUS transmitting end to Remote mode), as shown below:

• Enable serial port UART0 on the STA
• Select SBUS as the function
• Add a forwarding rule. Select UDP as the transmission protocol, Unicast as the operating mode, Local as the endpoint, and Receive as the data direction. Set the local listening IP to 192.168.1.3 and the network port to 8080, as shown below:

• After configuration is complete, you can use the remote controller to transmit SBUS data to the flight controller.
