List ,
I am following this tutorial to get latitude and longitude data using
NEO6 GPS module and Py PICO to read the GPS data from the device.
I followed the code specified in this tutorial.
https://microcontrollerslab.com/neo-6m-gps-module-raspberry-pi-pico-micropython/
I have installed thony IDE in my Desktop(windows PC) and run the code
after the devices all connected and using USB cable connected to my PC.
When I ran the program I am able to see the output of latitude and
longitude in the console of thony IDE. But between certain intervals of a
few seconds I am getting the latitude and longitude data ( its printing
GPS data not found ?? ) in the python console.
The satellite count from the $GGPA output showing 03 ..
and the GPS data not found repeating randomly for intervals of seconds.
Any hints why it is missing the GPS data (randomly) ??
PS:- The GPS device I placed outside my window and connected to the PC
with a USB cable from the PICO module. GPS device NEO6 light (Red LED
) blinking even though the " GPS data not found" messages in th python
console.
Any hints ?? most welcome
Yours,
Krishane

timeout = time.time() + 8
is too short. Most GPS receivers repeat a sequence on NMEA sentences and
the code is specifically looking for $GPGGA. Add
print(buff)
to see the sentences being received. I use the $GPRMC since I'm interested
in the position, speed, and heading. It's a different format but if you
only want lat/lon you could decode it in a similar fashion as the $GPGGA.

If it works (correctly*) some of the time, and there is only one look-up

in the code, it doesn't really sound like a problem with the Python.
* is it?
Does the unit also report the number of satellites it can 'see'? Is it
always more than one?
Other data not-discussed: change of cable, reducing length of cable, ...

From a retired broadcast engineer, intimately familiar with vswr:
std, wire only usb cables can get to acting flaky at 5 feet. If the
cable to the receiver is more than that, a higher quality cable may be
required. The better cable will probably have active electronics in the
molded on ends that treats the cable as a transmission line,
Which if done right can go as much as ten meters at usb2 speeds.
Cheers, Gene Heskett.

List,
Just commented the // gpsModule.readline() in the while loop, (
refer the link
https://microcontrollerslab.com/neo-6m-gps-module-raspberry-pi-pico-micropython/
)
while True: # gpsModule.readline() // This line commented out and the "GPS
not found message disappeared". buff = str(gpsModule.readline()) parts =
buff.split(',')
The GPS not found error which appears intermittently in the output python
console for few seconds ( say 7 to 8 seconds its printing the lines "
GPS data not found" ) now disappears.
Any thoughts? How the above line comment made it vanish the "GPS data
not found" error output.

Show the full text of the error that you see. Is it a traceback?
What I would do then is read the code that raised the "GPS data not found"
error and find out why it reports that error.
