Flir Vue Pro gets no Mavlink info

I’ve recently received back my Flir Vue from a friend and I’ve confirmed that the MAVLink communication with ArduPilot seems not to work anymore.

I’ve tried various changes to get it working but with no success:

  • Swapping TX and RX lines (SERIALx_OPTIONS has a bit to do this)
  • Change SERIALx_BAUD to 115
  • Changed SERIALx_PROTOCOL = 2 (MAVLink2)
  • Set SR2_xxx to 1 to send various mavlink messages to the camera
  • Disabled CubeOrangePlus’s ADSB by setting SERIAL5_PROTOCOL = 0 (I thought it might interfere somehow)
  • Reverted to Copter-4.2.3

BTW, my camera is running firmware VUE_PRO_V3.3.2. I suspect that it is the camera firmware version which has caused the problem.

I’ve sent a message to FLIR asking for older versions of the firmwrae so I can confirm the issue is on their side but who knows if they will ever respond. Until then I will add a warning to the wiki.

By the way, there is another similiar discussion here.
