Hi,

Some hints:

• NMEA0183 class could have setting for checksum checking. As far I I understood you have it now automatic. This may not be always good, if you know that devices should provide checksum. So there could be setting e.g.

class tNMEA0183 { public: enum tChecsumCheck={cc_Automatic, cc_NoCheck, cc_Force}; ...

• It is better to use reference in all functions, where you provide structure as parameter. E.g.

bool NMEA0183SetRMB(tNMEA0183Msg &NMEA0183Msg, tRMB RMB, const char *Src="GP");

causes explicit copy for whole RMB structure, which is pretty big. So it is better to use

bool NMEA0183SetRMB(tNMEA0183Msg &NMEA0183Msg, const tRMB &RMB, const char *Src="GP");

So that only reference to structure will be copied as parameter. There is no difference of use the parameter itself.
