NMEA feed
Post by zezo | 2020-05-28 | 13:44:52I've been asked (again) if it's possible to have boat data fed into 3rd party software by the VRDashboard. The purppose is practicing real-world nav software usage during VR races, but it should also be useful for collecting boat track/stats.
So I wrote a little sever that turns game data into NMEA feed over TCP.
Details below.

Hi 😉,
I installed the latest version (v3.9.1)
I tested the LA - Tahiti race on QtVlm (just to see)
• HDG -> OK
• COG -> OK
• SOG -> OK
• TWS -> OK
• TWD -> NOK
• TWA -> NOK

If you want, send me the corrected version by email before putting it here, I would test it 😉
PS: it would be possible to have the raceId in brackets next to the name of the race like this ?

Hi Michael 😉,
I installed the latest version (v3.9.2)
• Postion GPS -> OK (just a problem of display on QtVlm)
• COG / HDG -> OK
• SOG / BoatSPD -> OK
• TWS -> OK
• TWD -> NOK
• TWA -> NOK
I found this code (C ++) given by Maitai (Designer of QTVLM) on the web

I found this code (C ++) given by Maitai (Designer of QTVLM) on the web
AWA / AWS knowing SOG, TWA, TWS
double Y = 90.0 - twa;
double a = tws * cos (degToRad (Y));
double b = tws * sin (degToRad (Y));
double bb = b + sog;
aws = sqrt (a * a + bb * bb);
awa = 90.0 - radToDeg (atan2 (bb, a));
The reverse, ie calculate TWS, TWA knowing SOG, AWS, AWA
double Y = 90.0 - awa;
double a = aws * cos (degToRad (Y));
double bb = aws * sin (degToRad (Y));
double b = bb - sog;
tws = sqrt ((a * a + b * b));
twa = 90.0 - radToDeg (atan2 (b, a));

Right, the angle must be on 360 °. 😉
PS Did you see my email?

I modified the code for MWV and it seems to me that it works correctly now
function formatINMWV (m) {
// $INMWV Wind Speed and Angle (TWA not TWD)
var s = "INMWV";
s += "," + ((m.twa > 0) ? pad0(roundTo(m.twa, 2), 6) : pad0(roundTo(m.twa + 360, 2), 6)) + ",T";
s += "," + pad0(roundTo(m.tws, 2), 5) + ",N";
s += ",A"
return s;
}
function formatINMWV (m) {
// $INMWV Wind Speed and Angle (TWA not TWD)
var s = "INMWV";
s += "," + ((m.twa > 0) ? pad0(roundTo(m.twa, 2), 6) : pad0(roundTo(m.twa + 360, 2), 6)) + ",T";
s += "," + pad0(roundTo(m.tws, 2), 5) + ",N";
s += ",A"
return s;
}

I added the TCP port on my version (which is more practical than going to look for it in the console)
I will test the routers but I am confident if it works on 2 routers I think it will work on the others
function addSelOption(race, beta, disabled) {
var option = document.createElement("option");
var TxPort = 10000 + parseInt(race.id.substr(0, 3), 10);
option.text = race.name + (beta ? " beta" : " ") + " (" + TxPort + ")";
option.value = race.id;
option.betaflag = beta;
option.disabled = disabled;
selRace.appendChild(option);
}I will test the routers but I am confident if it works on 2 routers I think it will work on the others

@Michael,
It doesn't work as expected I think
I have this :
And I think that you want this :
nmeaGNInterval is declared but not used
