Thanks for the pointer Tom. I realize that it was not ideal and that some
NMEA traffic can leak into the following second if there is enough or if the
serial baud rate is too low , but the results with my lash up looked
unambiguous. I wouldn’t use the same method for any analysis.
Bit of news from my supplier. They have said they will send me a new module
with corrected firmware. All I requested was the firmware. Nice of them.
