Many thanks for the encouragement and bug reports. I will PM you later with some more details, (mainly about #4) but for anyone else following this thread… We will explore these issues and try to resolve them soon.

Hi dagnall, I'm not sure if this was intended, but the version you've attached is showing up as "Experimental CODE (CAUTION) Ver 2.02 Jun 2 2023 20:32:37" (so from last Friday) - is that really the latest version? Thanks for checking! I THINK.. ( I have been known to be wrong! ;) :oops: ) this is n...

NO!.. That was not my intention!.. MANY thanks!! I was tidying and must have sent the wrong one.. Before I complete my tests: I have added a GGA>datagrams 54,57,58 conversion. I think this probably removes the need to convert RMC or GLL > (optionally) 50/51 or 58. I will keep the "use datagram58" op...

Fabian, MANY THANKS for testing the code again! It is much appreciated! I cannot understand why the 16 bit conversion seems different in this Datagram.. but you have confirmed that this IS correct! (also - I have confirmed that our earlier ST58>NMEA conversion uses the same data configuration.. ) My...

'off' (sorry - you have never added your name!! ) I have sent you a PM with some extra questions.. Can you test this please to see if the minutes displayed on your ST70 are correct.. Luis FYI: I am concerned that the NMEA>ST conversion for datagram 58 sends the 16 bit minutes in a method that is no...

HI. Adding some code to generate ST57 from GGA turned out to be relatively simple. SO I have attached it here... PLEASE note that I have not been able to test this with a real GPS.. So I would very much appreciate if you can look at your GPS quality data (GGA) and check that the ST70 is displaying "...

Hi, That is good news, and I will have a look at decoding GGA or GSA properly to get the SeaTalk Datagram 57 "properly". Now bad news.. the 'Bible' of Seatalk datagrams does not tell me how the DOP data is transmitted. Jus that the Second variable (DD) is dop. I had assumed DOP was integer meters, b...

Bonjour, J'ai un problème d'affichage du COG sur mon répéteur GPS Autohelm sur bus Seatalk. C'est correct sur les COG de 0 à 90 mais au delà il n'affiche pas le bon COG. J'ai le traceur GPS TRACKER 5600 en P1 , l'émetteur AIS en P2 ( éteint pour simplifier la trace) et un bus Seatalk avec le sondeu...

Hi Forum, I use a NMEA3WIFI to connect my AvNav Raspi with a Raymarine ST60 Multi display and it works, but I get no speed data at the ST60. I logged the NMEA3WIFI and I can see the ST20 data but not on the display. Are this data correct and can I be sure that this data is on the SeaTalk? ray.PNG /...

This is amazing, it works! Just one last wish: If you could also send STALK 57 (Sat information) I believe this would allow me to also get the Time from the NMEA' GPS (even though I already see it sending the time, I believe missing #57 makes the ST70 think this might not be accurate). Would you in...
