Unknown Message (37) - AP 4.5 Dev

Trying to make a custom firmware for a Matek F405-VTOL. (I need to enable ICE support). By all accounts the firmware is working but the messages are being spammed with the line “Sending Unknown Message (37)” about 2-3 times per second.

I’m attempting the build with the latest 4.5 Plane. I’ve tried three different iterations with various other things turned off but it still keeps popping up.

Any suggestions?

Just did a build with 4.4.4 and everything looks normal. I’m not getting spammed with the “Sending Unknown Message (37)” anymore.
