I have a Jupiter-T GPS timing module board that is connected to a home
made board with a Microchip PIC 12F629 microcontroller. They form a
simple amateur radio GPSDO unit(GPS disciplined Oscillator for my
radio lab) They communicate eachother using serial TX and RX 5 volt
signals. Recently it has problems to get the fix and want to debug it
(antenna problem or module problem, who knows).
Maybe try running comms/minicom on the RPi to debug your setup.
Thanks, that is another software that I should learn to play. For now, I
am ok with "cu -l /dev/ttyU0 -s 9600|hexdump -C" command. It works fine
and I can see all bytes returned by the GPS module when asked with the
@@Ea command by the PIC microcontroller.:

I am going to try another spare antenna I have lying around.
