> Could you give me a bit more information on using WAAS? I used the Adafruit library to send it the message // Turn on WAAS GPS.sendCommand("$PMTK301,2*2E"); and after that the GGA message shows a fix type of 2 where it previously showed type 1. To see what mode it is in you can send it the PMTK401 message and it should respond with a PMTK501,2 if WAAS is enabled and PMTK501,0 if not. I believe this setting persists after power-down as long as you have a backup battery installed and don't do a full reset. WAAS only works in North America. I don't know details elsewhere, but the PMTK313 message says it turns searching for SBAS satellites on and off. -- --Jim Harman _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
