MAV1 and 2 revert automatically to higher update frequencies

General

Iam trying to set up a relay station, and I am trying to get the data from the flying plane to copter. It works, but the data which is transmitted to copter is dictated by MAV2 parameters for MAVLink2 option of the UART, as far as I understand.

However, when I try and save different MAV2 update frequencies, it works for a while, but on a reboot, higher freuquencies are reloaded. I.e. I change all but 2 MAV2 parameters to 0, leaving just two with a value of 2.

After a while (on reboot, it seems), they go back to 4/2/1 update frequencies.

It is on F405 controller (Speedybee).

Also not sure, if I change MAV1 update frequencies to 0, then MAV2 posssibly reverts to higher values, and vice versa, but I am not sure, as the change does not follow a clear cut pattern.

Any ideas?

The behaviour seems to be: I save MAV2 parameters, they revert immediately to some preset values. I save MAV1 parameters, they stay as saved.

Could it be the GS (Mission Planner) resets them to its liking? Because I have also bluetooth connection to GS?

The first Mavlink link is mav1 the second mavlink is mavlink2. If mp is connected to the second mavlink link, then it will take full control of the messages rate of that link.

Is mp the second mavlink link?

yes, and it seems that by changing Planner update rates I have solved the issue… it was a very obvious thing after you realize it, but very perplexing the first time.
