Support for external receiver via NMEA over TCP

[pyrog]

Some GNSS receivers could send a NMEA stream over TCP (port 1958 by default).
The receiver could be a client of your app (SMASH is the TCP server)…
or the server (SMASH is the client).

Softwares

• Vespucci an OpenStreetMap editor

GNSS receivers

• Sparkfun RTK devices
• Emlid Reach M2

That is a long time wish also for us. But we never had a usecase paying for this kind of implementation.

At this year's foss4g I sopke to someone from HOT that told me they are testing external low cost devices. Maybe the two thing could finally lead to an implementation. Let's see. Thank you for the input.

Also, Ardusimple devices are like this, and more importantly, don't do bluetooth. So while this issue is valid, the real point IMHO is "enable smash to work with the above 3 devices while the devices get RTCM3 via NTRIP over the internet, and while they get it separately".

For information:

• TCP port 1958 is the port used by Vespucci.
• UDP and TCP ports 10110 are registered by the IANA for NMEA.

There are some Android applications which are able to connect to external receivers and provide a "mock" location, even over TCP. It could be worth trying a couple of these in the meanwhile.
