Reply To: Jumbled binary output – known issue?

Hi Bob,

That’s very interesting. I haven’t observed that problem directly before, but the Serial Interface does automatically retry if it doesn’t get a response, or if it receives a packet with a bad checksum. And when the Serial Interface does attempt to read the FW revision, it occasionally does receive a packet with a bad checksum. So this may very well be a bug. I’ll look into it.

In the mean-time, make sure that you validate the checksum before accepting a packet, and on bad checksum, request the FW revision again.
