Am working on custom NMEA sentences for a wind sensor, now i do have the whole sequence complete up to the checksum at the final end, checksum is calculated correctly when i compare this with a NMEA simulator but what i can see is that the calculated checksum in Node Red ends with a small letter while the correct format must be in Capital letter.
i have an example overhere :
$WIMTA,22.5,C*1E is send out from a NMEA simulator
$WIMTA,22.5,C*1e is send out from Node Red,
it are just the Alphabethical letters in the checksum which are in small and which must be capital to be conform the NMEA standard. Anyone out there who can help me ??
