General:

Notes

  • Jae #Cellular modem config

    • #1421 Define cellular config messages for configuring Modems and #1323 Improve cellular status mavlink message
    • MD5 for mirroring back pins is not secure. Could use SHA2 but is not forever future proof. Suggestion is that it shouldn't be sent back at all.
    • Bands story a little unclear - big enum of bands that is likely to grow, not completely clear how the blacklist will be used or whether a whitelist would be better. Proposal is to strip that out for now and come back with more clarity on use.
    • Decided not to add the continuous quality metrics.
    • Jae to split this into a separate PR for the bands stuff so we can get this in soon and iterate the less clear stuff.

  • Hamish #1414 Add auxiliary actuator commands

    • Proposed replacement for DO_SET_SERVO command - actuators mapped to arbitrary actuators using normalised values (not PWM) via flight stack mechanism (e.g. params)
    • Essentially we are all in agreement just that the "proposal" hadn't been updated it the right place, so that wasn't clear (ie this should not be AUX specific).
    • Kalyan to update in line with discussion. It is to have index to allow larger numbers of servos to be set.

  • BATTERY_STATUS.voltage: 10 cells to 12 cells #1412

    • DONE This should be done as an extension. Hamish notified them.

  • COMPONENT_INFORMATION - implementation, anyone?

    • No information on this yet internally. Julian suggested we raise request for support on the PX4 channels at least to see if we can get community involvement. Hamish to act on that.

  • FYI MAV_PROTOCOL_CAPABILITY_TERRAIN - to mean "supports frame type" - we agreed not, but Don really wants to reuse this capability. Chasing up with James offline.

    • Just update on this. Essentially it is on hold. But PX4 are OK with this being used for the proposed purpose.James to let us know his feelings after that meeting.

  • Add ESC_INFO and ESC_STATUS mavlink messages #1322 - the address appears to be for UAVCAN nodes. We suggest remove as these are not used by PX4. Can be added back if needed. Hamish to update.

  • Gimbal update

    • Conflict resolution still problematic even with intents. Julian is progressing.

Not discussed:
