The previous forwarding rules exclude another onboard MAVLink node to
send messages to a specific target.
E.g. a message from a companion computer with sysid 1 (same as
autopilot) with target sysid 190 (for the ground station) was not
forwarded.
With the new rules, anything that is not specifically addressed to the
autopilot's sysid and compid is forwarded.
This avoids premature state machine execution, most notably for missions.
In particular this fixes these issues:
- when landed, and the vehicle has a valid mission: switching to mission
would execute the first item.
- after executing a mission with a land waypoint, the mission is reset
and the first item is executed.
In case the first waypoint is a takeoff, it would print a user message:
"Takeoff to x meters above home.". If it was a vehicle command, it would
execute that.
Note that because the vehicle is disarmed, the vehicle would not actually
do anything (except for commands that are accepted while disarmed).
This will allow navigator to not output any setpoints while disarmed.
Otherwise the position controller outputs warnings in the form of:
Auto activation failed with error: Activation Failed
The risk here is that it could hide problems, where navigator sends invalid
triplets when it should not.
- uORB::SubscriptionBlocking is a specialized uORB::Subscription that allows you to do a blocking read
- this is intended to be an easy to use, hard to misuse replacement for the typical orb fd + poll pattern we've relied on historically
- landed, maybe_landed, or ground_contact required before the safety
button is able to disarm
- this reduces the risk of a faulty safety button triggering in regular
flight
- this is a new module for temperature compensation that consolidates the functionality previously handled in the sensors module (calculating runtime thermal corrections) and the events module (online thermal calibration)
- by collecting this functionality into a single module we can optionally disable it on systems where it's not used and save some flash (if disabled at build time) or memory (disabled at run time)
