Hi, I have researched this topic and have determined that my problem is due to changing the baud rate that doesn’t match with the Sonic board. Worse is I dont remember the value that I changed to in the Flight parameter page. So I believe my option is to build a flight firmware w a hardcoded baud rate at 625000. I’m a complete newbie in development and was trying to read up on the wiki but so far its gone way over my head.
Can someone please provide some help on how to build a firmware or provide one ?
Thank you so much all.
