[drats_users] Arduino and D-RATS

[Timothy Le]

Hi,

     I was talking with Dan a few weeks ago about sending the GPS
coordinates from an Arduino microprocessor and getting the results to
display on the map. He also recommended that I post on this mailing list to
discuss the solution. I now also need the capability to send text to the IM
interface of D-RATS. I've been able to output a message sent from D-RATS
into HyperTerminal and what I concluded from that is that there is some type
of message ID and checksum value that needs to be calculated upon
transmission of the message and a check on the receiving end of the message.
I'm working on a homing system for firefighters that sends the GPS results
to the map screen and sensor data to the IM screen. Could someone fill me in
on how this checksum works? Thanks for your help.
