Hi,
I'm buiding a NMEA0183 multiplexer. (MBED microcontroller) the only thing the controller does is buffering the messages from an Actisense DST (currently installed in the boat so excluded from the test) a GPS module and a NASA wind masthead.
When I use minicom to capture the incoming NMEA-data it reads:
However, when the mux is added under serial devices in OP only the GPS sentences are read, captured and forwarded to SignalK.
When the two devices are fed in to OP with separate (Homebuild) NMEA-USB converters all works fine.
Is this a bug? Am I missing something?
