> @peterbarker When do you plan on running a test(s) with many waypoints to evaluate the cost of this operation? ``` AP: Took 2.178000ms to checksum 373 points (5.839142ms/1000 points)...

I've modified MAVProxy and pymavlink to use the checksum feature to avoid uploading a mission if it is identical to the one on the vehicle: https://github.com/ArduPilot/MAVProxy/pull/1104 ``` MANUAL> wp load...

The patches in here are now updating the checksum progressively to avoid the scheduling problems.

@hamishwillee we discussed this in today's DevCall. This is now end--to-end working. We're not sure of the utility of this in the face of mission-transfer-via-ftp, however. Could you summarize the...

> @tridge Thanks very much. That's disappointing. just to clarify with this current PR. A GCS can't create a mission, checksum it, ask the autopilot what checksum it has and...

> It is "slightly beneficial" if this is an opaque checksum of the file because then a change to the mission that reverts a change would still match on GCS...

> It is likely that ArduPilot _knows_ that it doesn't support certain parameters in certain commands and chooses not to store those. SO if the params have values in the...

Current 2022-10-05 17:05 New theory is that we will not have a mission specific to the checksum, rather inform the GCS of the ID of the mission currently being executed...

@timtuxworth a lot of what you desire there is really outside the scope of what the autopilot can be expected to do - particularly in regards to workflows, which are...

> Would be happy to test this out / provide feedback (btw, I'm @aburka on Discord). I'd be using a CubeOrange or PH4-Mini. Strongly suggest testing this on something *other*...
