Notes

• Move BlueROV projects into MAVLink - Discuss

  • https://github.com/bluerobotics/mavlink-camera-manager
  • https://github.com/patrickelectric/mavlink2rest - REST API for MAVLink
  • Both are pure MAVLink - no "flight stack" specific behaviour or branching.
  • Camera needs more docs.
  • License looks good but we should let Ramon know.
  • Good history of maintenance and professional engineering practice.
  • Both would be very welcome in MAVLink - higher profile and more likely to be used as base for other projects.
  • Also interested in getting the PyMAVLink docs.
  • AO HamishW to talk to Ramon

• Command int long fixes #1992 - tools docs update following common.xml: Add MAV_RESULT_COMMAND_LONG_ONLY and MAV_RESULT_COMMAND_INT_ONLY to MAV_RESULT #1982

  • OK to try create the other attributes. Text broadly looks OK.

• Are there any deprecated we think are really deprecated (i.e. ardupilot and PX4 happy to dump). Just to seed start of discussion.

  • SOME of the MAV_FRAMES. Maybe MAV_DATASTREAM. Need to test/grep.
  • James: Use as opportunity for deprecation to mean something. I.e. as part of this turn on the deprecation use flag. Should not affect many if they are really deprecated.

• XSD - can we get these merged?

  • mavschema.xsd - max, min, increment on field #811
  • mavschema.xsd: add superseded tag #809 #809
  • XSD Schema - there can be at most 7 params #814

• Replace validator with xmlschema (XSD1.1 compliant) #816

  • Python 3.7. Only a dependence Ubuntu 18
  • not so much a big deal as you don't build/validated from source usually on things like Jetson. And in fact the only place you need to validate is if adding new messages.
  • Little more work to have lax checking - is that needed?

• Added "shortest way" as an option for yaw direction in MAV_CONDITION_YAW #1962

  • FYIAndeK stuck on ArduPilot bug I think.

• mavlink_msg_xxx_decode by mavgen_c does not handle extensions of message properly #684 - pymavlink bug fix

  • AO JamesP to see if we can get review from PeterB

• Need a better way to call python generator - from Pymavlink - get answer?

• message_definitions: add all_with_development.xml #1924

  • JamesP seeking more suggestions.

• 1978 Wireshark mavlink_2_common.lua:9330: bad argument #1 to 'rshift' (number expected, got nil)

  • Some progress FYI - Roku (Dan Rose) fixed that bug but is looking at other problems with output.

Attendees: Hamish, JamesP, JulianO, Patrick from BlueROV (@patrickelectric)
