Re: NEO6 GPS with Py PICO with micropython

[KK CHN]

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.

NEO6 GPS with Py PICO with micropython

[KK CHN]

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

Python code: brief

[KK CHN]

List ,

I have come across a difficulty to understand the code in this file.  I am
unable to understand exactly what the code snippet is doing here.

https://raw.githubusercontent.com/CODARcode/MDTrAnal/master/lib/codar/oas/MDTrSampler.py

I am new to this type of scientific computing code snippets and it is coded
by someone.  Due to a requirement I would like to understand what these
lines of code will do exactly.  If someone  could explain to me what the
code snippets do in the code blocks, it will be a great help .

Thanks in advance
Krish
