Bad custom dialect routing(CRC).

[Derker2002]

Bug Report

I was trying to implement a custom command to control the onboard computer via MAVLink. I saw that ArduPilot 4.7 can route packets with bad CRCs.(PR) But unfortunately, it is not working at all. QGC is not arguing that the command is unknown, and FCU does not route it to the onboard computer. If I send a command straight to the onboard computer, it works. The issue lies within the FCU itself.

Issue details

FCU does not route custom dialect commands to components when the ‘MAV2_OPTIONS’ parameter is set to 8. Aka bad CRC packets.

Hi @Derker2002,

Any chance that you have an onboard log? That will allow us to check that the configuration has been done correctly.
