Node Red NMEA node not accepting GPS information from Arduino Serial

Hope you are having a nice day.

My issue is related to a NMEA node not acting properly when I send it GPS information received from an Arduino or Inject function. It is being sent via serial and has supposedly the correct format. I tried the same using a VK-162 (USB GPS) and it is working well. But when I try to send a message with a format like:

$GPGLL,4916.45,N,12311.12,W,225444,A

Inject Function error

or with the Arduino, I get the following in my debug area:

Arduino error

If someone could give me some insight I would greatly appreciate it :)

All the best.

Solution

  • It looks like you are missing a checksum from the end of the line

    All of the following work

    $GPGLL,4916.45,N,12311.12,W,225444,A*31
$GPGLL,5133.81,N,00042.25,W*75
$GPGLL,3751.65,S,14507.36,E*77
