Gremsy T7 stopped listening to mavlink messages (?)

Hi all,

I have a CubeOrange+ running ArduCopter 4.3.6 and configured to work with a Gremsy T7 with firmware 7.7.1. I set up everything just like described by @rmackay9, and everything worked on the first try. The “Point to this coord” function in MP was working just fine for a few days until yesterday. Today the gimbal decided to stop listening to the commands even though I can see the LED is purple on the back of the gimbal, which means good mavlink message communication. I could not get it back to work even after reflashing the firmware and several reboots (and yes, I waited until GPS home lock was acquired). Could anyone here please help me find the problem?

Thank you!

Disregard this issue. Faulty wiring was the culprit.
