I have a Kakute H7 running INAV 4.0.0
I have a holybro nano GPS module
And two BeiTian BN880 GPS compass modules
They didn't know why the compass turned red at first, but they didn't know why it worked normally.
This seems to have something to do with the I2C bus, because I was configuring my vl53l0x rangefinder when this happened for the first time
The second appeared when I removed the bno055 sensor
I can't solve this problem. It looks like the compass is broken, but I know it's not
Even if I set the compass to "NONE", it will display red, and then won't let me disarm
Maybe it's because I modified the speed of the GPS module? It shouldn't matter
