Generate custom NMEA0183 sentence in v0.8

[CVL]

Hi all,

Now to my question. I want to feed temperature and pressure into OCPN. v0.8 of OP generates the $OSXDR NMEA0183 sentence but OCPN does not handle that so I'd like to generate different sentences appropriate to OCPN (MTA for temperature for example). How do you change the sentences generated by OP is there a hidden interface somewhere? 

Thanks in advance

Hello

Look at 1w.py in the the OP directory (normally ~/.config/openplotter or something like this)

I changed the sentence which is generated in this file, as my cockpit instrument will only read and show MTW sentence. But I want it to show the value from the DS18B20 sensor ... so I changed the values in 1w.py from XDR to MTW.

Thanks Christian. I had already found that but not been back here to update.. I haven't got the pressure to display in OCPN but haven't spent a lot of time on finding out what sentence it uses. Temperature was easy. I've been busy making a script to generate a polar file from logged NMEA data.

Hi Chris,
no problem. If you get your script running I would be interested...
