Seatalk - bogus values
Posted: Tue Sep 22, 2020 9:43 am
Using the NMEA2WIFI connected to a SEATALK network.
When logging all the received values, I see some bogus values from the wind/speed/dept sensors.
The checksum is correct, I guess the error is on the SeaTalk side. All GPS messages are OK.
Some examples from the log.
Wind Speed and Angle, angle and reference are missing
2020-09-20 15:06:09,$VWVHW,,,,,3.30,N,,,*34.
Wind Speed and Angle, angle is too big.
2020-09-20 15:06:09,$WIMWV,31240.5,R,6.0,N,A*24
#Depth Below Transducer, sometimes give out very big values, int this example 4096 (2^12)
2020-09-20 13:56:17,$SDDBT,57.1,f,,,,*3E
2020-09-20 13:56:18,$SDDBT,56.8,f,,,,*36
2020-09-20 13:56:22,$SDDBT,57.3,f,,,,*3C
2020-09-20 13:56:23,$SDDBT,4096.0,f,,,,*36
Is there any sanity check on the received SeaTalk messages in NMEA2WIFI?
