NMEA sentence for Instrument Panel Barometer?

[Hakan]

Hubert
I know, but still is the unit abbreviation B used for Bar as in the more formal though obsolete MDA and not mBar, I suppose. And our Dashboard reads B as Bar.

A conversion has been added to the OpenCPN Developer Manual page for the NMEA converter plugin that allows correction of BMP180 pressure readings and conversion to Bar. OpenCPN Dashboard running on a Raspberry Pi (RPi) with OpenPlotter now shows the presssure correctly, although readings are given to the nearest hectoPascal. This conversion could also be useful if OpenPlotter output is being fed to OpenCPN running on other computers

Transmitting the pressure with XDR sentences is working fine now, just a pitty that the automatic entry of temperature and pressure into the konni logbook plugin is so fragile and inflexible that I only got it to auto-enter once.

Is anybody using the logbook plugin?

I use the konni logbook every time the boat moves, the only way I could get the barometer/hygrometer/air temp was to convert the $OCMDA nmea sentence created from a BMP180 sensor (no hygrometer reading so the logbook autoentry is to zero) created by openplotter on a raspberry pi to $WIMDA like -
$WIMDA,,,1.018,B,22.6,,,,,,,,,,,,,,,*2A

Nearly always gets entered automatically when a new line is entered in the logbook.
This is done in node-red running on the Pi.

This statement "Nearly always".. is in my case "only sometimes" - rest I do exactly like you. I just find the logbook very fragile and buggy. Got the impression nobody really uses it as some irritations are too obvious not to get noticed by any user. Glad you got used to it as it is, I still hope for some programmer to smooth things out.
Don't really see the value to have the logbook as a plug-in to opencpn, would rather prefer to lift it into an independent app and feed NMEA data from e.g OpenPlotter. Have raised this before but got informed that this is not possible.

Thanks conachair for your comment!

I've been using it for some time now, apart from sometimes not accepting WIMA pressure sentences it's been solid, and pressure gets logged short term elsewhere on my system anyway so it's not a big deal for me if it misses it once in a while. AFAIK The original programmer is no longer involved due to ill health , someone else did some work on it but nothing for a while so we might be stuck with what there is for now.
Living onboard full time I find it really useful logging where and when the boat moves with a click rather than filling up log paper logbooks. If there is a need to log anything then opencpn will be running so for me it's ideal as a plugin.

Regarding logbook konni. Peter tulp (ptulp) and others have been active in updating and maintaini g logbook konni. There are avid users so don't despair. Please write your problems in detail with all the debug sleuthing in Tracker, under the pluggin, and contact ptulp. He is tremendously helpful.
Thanks.

Thanks Rick for following up- could you pls also add a " pi - logbook" section on the tracker. I fear under the general feature requests its lost.

Cheers - Freddie
