Array and ASCII

Have you tried to send some test strings? something like:

SEROUT2 bob, baud, ["$GPRMC,220516,A,5133.82,N,00042.24,W,173.8,231.8,1 30694,004.2,W*70"]



If that works, try this (assuming Heading is the variable that contians your heading data):

SEROUT2 bob, baud, ["$GPRMC,220516,A,5133.82,N,00042.24,W,173.8,",DEC3 Heading,".0,130694,004.2,W*70"]
