Hi,

I have the following 5G rb5
system-image: 1.7.1-M0052-14.1a-perf-nightly-20231025
kernel:       #1 SMP PREEMPT Thu Oct 26 05:24:02 UTC 2023 4.19.125
--------------------------------------------------------------------------------
hw version:   M0052
--------------------------------------------------------------------------------
voxl-suite:   1.1.2
--------------------------------------------------------------------------------
current IP: wlan0: 192.168.1.37

After flashing and setting up the IP address, I can ssh in the drone but I cannot connect to the drone to the QGC.

The port setting is 14550.

Any help on this?

Best wishes,

@tahawaru 

And in the flashing process, which number should be chosen from this list:

@tahawaru You should select `8` for `rb5-flight`

@tom 

After flashing, I cannot connect to the QGC.

After setting up the IP address, I try to connect via UDP using the IP and port 14550, this is what I get

drone(connected) is the one not connecting to QGC.
