Hi,
I have been setting up my configuration of my APM2.5 with 3DR Radio Telemetry link.
I've noticed what seems to be quite a serious problem. I am powering my plane using my Lab PSU which limits current. If the motor kicks in and triggers a current limit and triggers the APM to reset, the telemetry link will not be established.
To re-link I have to unplug the ground radio and back in again, and cycle the power to the APM2.5 (and therefore power down the air radio), then the link is reestablished.
Any ideas why after a brown out the link fails. Is this an issue with the APM2.5 or APM Mission Planner not sending the correct command to reset the link? or is it something i need to configure in the radios? i.e. they only 'pair' when turned on at the same time?
Thanks

I've raised this as a defect Issue 780 as I think that without this fixed, safe flight can only be better supported if the APM uses a separate power source. brown out seems like a very likely issue when battery power is getting lower.
If you lose telemetry due to power on the output side being low, you more likely to lose your plane, even if you kill the motor so you avoid the excess power drain, the APM won't restart and possibly send an updated 'last know position'
