If possible, enable "Replay Logs", reproduce the problem, and provide a copy of the logs in http://192.168.10.1/logs/stratux/ and http://192.168.10.1/logs/stratux.log.

Seems like a fairly innocuous error. Looks like we're parsing the string and assuming it is null terminated but it's not.

What are those characters? If you "cat -e" the logfile it'll show you character codes.

I'll take a look at it.

FWIW, I got confused by these characters in the logs a few months ago when we were troubleshooting the failure of the Edimax. I saw the characters and posted a snippet for Chris, thinking that was when the failure occured. #267

Yeah, I'll just have to add in some extra string handling. It should not affect function.

Here is the result for the 1090 SDR:

Update: I cleared my old log and created a new one so you could see the whole log with the interesting character. What I was aiming for was to see the 1090 SDR gain setting like used to be in the stratux.log, but I think it may have been removed. Edit: Wrong log. Sorry.
