Anyway, questions I have:

1. I am using this plugin on a Windows machine. I used the .exe to install it. Is this package current with your updates? If not, how can I get an updated .exe installer

2. I have OpenCPN installed on a raspberry pi and would like to utilize the plugin on it. I have no idea how to install the plugin on the Pi 3.

Again, awesome plugin!

For the raspberry pi using the built in program node-red might be very well suited 5o do what you are doing, not too difficult to program and you can save all the data straight into a file or database with a time stamp.what messages are you using, is it the openplotter image?

I am using Open Plotter.

with regards to sentences:

1. GPZDA: Field 1 (UTC Time)
2. VMVBW - Field 1,2 (Transverse Water Speed, Longitudinal Water Speed)
2. GPGLL - Field 1,2,3,4 (Lat, N/S, Long, E/W)
3. HDHDT or GPHDT - Field 1 (Heading True)
4. GPVTG Field 1,5 (COG, SOG)

For reference, you can see our sensor design at Electromagnetic Speed & Leeway Sensors for Performance Sailboats

Found error again and corrected as below.

$XXMWV,$WIMWV1+acos((sqr($WIMWV3)+sqr($GPRMC7)+sqr ($WIMWV3)-2*$GPRMC7*$WIMWV3*cos($WIMWV1*3.14159265/180)-sqr($GPRMC7))/(2*sqrt(sqr($GPRMC7)+sqr($WIMWV3)-2*$GPRMC7*cos($WIMWV1*3.14159265/180))*$WIMWV3)),T,sqrt(sqr($GPRMC7)+SQR($WIMWV3)-2*$GPRMC7*$WIMWV3*cos($WIMWV1*3.14159265/180)),N,A

In terms of sog vs. stw, as pointed out, in most cases, diff is negligible I believe. One thing about stw is that the sensor cannot capture the movement of a vessel due to tide (as high as 5 knots!). For my purpose, gps is good enough.

Thank you. I will add this to supplimentary hardware!

If you have a paragraph for us to add, put it in this thread.

ZZZ i've changed it in the manual.

Isn't it time to move this plugin out of beta?

Almost there still are a few know bugs

[zzz]

The sensor sounds great. When speed through water is zero, can this read movement of water/current? Speed and direction?

Airmar also has a similar sensor.
DX900+ MultiLog Sensor

They do, but at a price

Thanks for the information. Now I learned that this one and the other one are both electromagnetic sensor therefore cannot capture movement of water or vessel move along with current. Doppler ones can do that but too expensive...

Windows NmeaConverter_pi update.

RooieDirk Correct double entry's when reopening dialog 3 days ago

Made another push to the git source.
Now it is possible to use wildcards in the identifiers. So you could make it talkerid independent bij using something like .....$??XXX3.... , and whatever character on the ? position will cause a hit.
And maybe more important, you might use it for special transducers sending the something like $OWXDR,H,....or $OWXDR,C.... sentence. Note that field 1 is part of the indentifier. As the comma is the nmea separator, you can not use it as an identifier string, but by using a wildcard it works. For example ....$OWXDR?H2... or $??XDR?H2.... will work.
If there will be no bug reports the next few weeks, I do request for a final 1.0 status.

Please test this new windows pre-release of nmeaconverter_pi-0.9.

Thank you Dirk.

I added this to the Wiki
