How can I switch Tel1, Tel2 connections?


I connected LTE module to Tel1 and SIK radio to Tel2.

QGroundControl has been connected as follows.

When I click on the radio connection, there is no response.

Is there any other way to and from QGroundControl to check the status of Tel1 and Tel2?

Best Regards.


Does the SiK connection work? Is this with Pixhawk 6X? Try disabling flow control using MAV_x_FLOW_CTRL.

yes. SiK is working.

my flight controller is Pixhawk V5+.

V5+ doesn’t have MAV_x_FLOW_CTRL parameter, is it?

I will attach related images.


Don’t worry about flow control if SiK is working.

I have no idea how that LTE module works, so I probably can’t help with that unless I know more.

A good idea is always to use wireshark to see what is going on.
