Communication restoration between Sonic board and FC

[lordneeko]

Changed SERIAL1_BAUD, easier way than using a external serial adapter?

According to the Dev Wiki I connected to the SkyViper. With the command baudrate 115200 I changed the baudrate of the Sonix board to my changed setting. Than I connected QGC, after that I had all the parameters on the parameters page. There I changed it back to the default 625000 baud. Thanks Warren for your hint!
