PX4 parameter UXRCE_DDS_CFG missing

To connect PX4 (CUAV v5+) with companion computer (rpi) (by following this tutorial Raspberry Pi Companion with Pixhawk | PX4 User Guide) UXRCE_DDS_CFG parameter need to be set to 0. But the parameter is not available in QGround controller.

PX4 version - 1.13.3 (latest stable)

@Thasindu_Wickrama , uXRCE-DDS is available for v1.14 onward. If you want to use v1.13 you have to use microRTPS.

Hello, i use the 3DR Pixhawk 1 Flight Controller. Use QGC upgrate the firmware , the QGC detect the 3DR Pixhawk 1 Flight Controller is FMU_v2,then installed firmware version is PX4 Pro Stable Release v1.14.0. But UXRCE_DDS_CFG is not available in QGC, do you know what’s wrong. thx
