Theory of MAVLink routing:
|
2014-12-16 03:40:39 -04:00
|
|
|
|
|
|
|
When a flight controller receives a message it should process it
|
|
|
|
locally if any of these conditions hold:
|
|
|
|
|
|
|
|
1a) the message has no target_system field
|
|
|
|
|
|
|
|
1b) the message has a target_system of zero
|
|
|
|
|
|
|
|
1c) the message has the flight controllers target system and has no
|
|
|
|
target_component field
|
|
|
|
|
|
|
|
1d) the message has the flight controllers target system and has
|
|
|
|
the flight controllers target_component
|
|
|
|
|
|
|
|
1e) the message has the flight controllers target system and the
|
|
|
|
flight controller has not seen any messages on any of its links
|
|
|
|
from a system that has the messages
|
|
|
|
target_system/target_component combination
|
|
|
|
|
|
|
|
When a flight controller receives a message it should forward it
|
|
|
|
onto another different link if any of these conditions hold for that
|
|
|
|
link:
|
|
|
|
|
|
|
|
2a) the message has no target_system field
|
|
|
|
|
|
|
|
2b) the message has a target_system of zero
|
|
|
|
|
|
|
|
2c) the message does not have the flight controllers target_system
|
|
|
|
and the flight controller has seen a message from the messages
|
|
|
|
target_system on the link
|
|
|
|
|
|
|
|
2d) the message has the flight controllers target_system and has a
|
|
|
|
target_component field and the flight controllers has seen a
|
|
|
|
message from the target_system/target_component combination on
|
|
|
|
the link
|
|
|
|
|
|
|
|
Note: This proposal assumes that ground stations will not send command
|
|
|
|
packets to a non-broadcast destination (sysid/compid combination)
|
|
|
|
until they have received at least one package from that destination
|
|
|
|
over the link. This is essential to prevent a flight controller from
|
|
|
|
acting on a message that is not meant for it. For example, a PARAM_SET
|
|
|
|
cannot be sent to a specific sysid/compid combination until the GCS
|
|
|
|
has seen a packet from that sysid/compid combination on the link.
|
|
|
|
|
|
|
|
The GCS must also reset what sysid/compid combinations it has seen on
|
|
|
|
a link when it sees a SYSTEM_TIME message with a decrease in
|
|
|
|
time_boot_ms from a particular sysid/compid. That is essential to
|
|
|
|
detect a reset of the flight controller, which implies a reset of its
|
|
|
|
routing table.
