Am trying to send FC bootloader information from an STM32 to a K60. (Please don't ask why!)
The protocol document AN2295, to me, is not clear on a couple of things:
1. How do you delimit frames? ie How do you know a byte you are looking at is the first byte of a frame?
2. The headers seems to be ASCII bytes and yet the binary seems to be binary. IS that really the case?
