I'm not having much luck uploading a route to a Magellan GPS 320
following the Data Transmission Protocol specs.
According the specs, the route message format is as follows:
$PMGNRTE,xx,xx,c,n,c----c,c,c---c,c,c---c,c,.......*hh<CR><LF>
I'm sending the following message to the GPS with SerSend():
"$PMGNRTE,1,1,c,1,ROUTENAME,KLAX,a,KSNA,a,KLGB,a*1D\r\n"
"$PMGNRTE" is the route message identifier
"1,1" indicates message 1 of 1
"c" indicates a complete route description
"1" indicates route number
"ROUTENAME" is the name of the route
"KLAX" "KSNA" "KLGB" are 3 user waypoints on the GPS.
"a" indicates icon type
"*1D" is the checksum
"\r\n" is the <CR><LF> terminator
Am I formatting the route message incorrectly? I seem to be
able to upload waypoints without any trouble, but my route
upload doesn't seem to work at all... Can someone provide me
with a route message sample confirmed to work so I can
compare to mine?
Thanks
