I designed a board based on the fmuv4, and the configuration is similar.
Then i connect to QGC, The QGC also reads the parameters on my flight controller
but when I set (e.g. modify a parameter) or send command it stays unresponsive.
then I gdb debug it step by step, and I found that there is a message received, as in the following picture, but it’s not clear what it’s about.Now I have no clue,has anyone encountered this problem?
And I’m using a USB virtual serial port to connect to the QGC. maybe some configurations are not configured correctly?
