FCU Packet drop issues

[PenceMataria]

There had been the issue of message drop in the mavlink connection since the time when we started using USB-SERIAL connection for FCU and companion computer link. Apart from it the QGC did shout to us onboard controller lost ; we ignored it but during some recent tests with avoidance ON, the MAV went to hold mode in between or start of mission, we dismissed it with ground station considering it as battery issue (it shouldnt be since all the battery saftey actions were limited to warning) because simultaneously the PM was reading wrong battery levels.

However on analysing I found the message logged Obstacle Avoidance System failed, loitering and thus the packet drop issue can be a severe problem for avoidance.

I found a validation for the same at PX4/PX4-Avoidance#303 .

So is it happening only with avoidance or everything?

[PenceMataria]
