idea for store bought items

[PaddyB]

if , under openplotter menu I click signal  K, and then diagnostics, I can see new BME280 sensor and all three fields, I set them up for 1 sec update at this time.

So, now I goto tools/nmea0183 generator
ADD
then, no matter which sentence $-xxx I select, if I hit RMC examp, it will not populate the selected sentence type.
If that is not how to use the function please elaborate and let me know. I'm still not sure if I use XDR or MDA either, seems to be some confusion on the net over this.

The MDA sentence is understood by opencpn dashboard. This is from openplotter.conf on my system...

['MDA', ['', '', ['environment.outside.pressure', 'x.xxx', '/', 100000.0], '', ['environment.inside.temperature', 'x.x', '-', 271.15], '', '', '', '', '', '', '', '', '', '', '', '', '', '', ''], 1.0]



Hope that helps, it's actually very handy to have the pressure live on opencpn , especially if, like me, you use a tablet in the cockpit. The dashboard has a graph function as well so you can watch for trends.
