agoransson / mqtt4processing Goto Github PK

Hi, I've used mqtt4processing to display a map of the 16 thermal sensors in an omron D6T thermal camera. It works pretty well - I know nothing about graphics but got something going in a few hours.

I had a problem, though. I send data from the camera (read by an arduino) as an mqtt message
224,204,205,206,205,198,198,197,193,193,196,192,191,196,197,194,192,f9

But this is delivered to the callback as

24,204,205,206,205,198,198,197,193,193,196,192,191,196,197,194,192,f9

ie, the first character is lost. I've got around this by putting a 0 on the front of the string, but I'd like to fix it properly and I'm too new to Java to get anywhere fsat. Don't even know how to rebuild the library!

The message is printed exactly as I'd expect by mosquitto_sub.

I've used the 0.1.3 release bundle.
