Hi Alex
To me, it looks like it isnt random rubbish (problem with serial line) as the characters always appear in the same place. Maybe it is UBX messages.

Is echo disabled on the serial interface?
stty -F /dev/serial0 -a

You can try and reset the GPS using this command from /dev/ttyGSM2
AT+UGUBX="b56206040400ffff02000e61"

If this doesnt work, please send an email to sales @ ozzmaker

Hi
If you are outside and you do have clear access to sky... you should get a fix within 30mins. So.. something isnt right.

Can you please try to reset the GPS module;
echo -e -n "\xb5\x62\x06\x04\x04\x00\xff\xff\x02\x00\x0e\x61" > /dev/serial0

[richardp]

try
sudo apt-get install python3-smbus

[richardp]

No. As long as all the connections are clean and you make sure GND continues along the length of it.

You may have missed Peter's email. I just forwarded it again.

We created the test program.
Please download this file into the same directory as the current code you are working with.
You can use a wget
wget https://raw.githubusercontent.com/ozzmaker/BerryIMU/master/selfTest-LIS3MDL/selfTest-LIS3MDL.c

Compile with
gcc -o selfTest-LIS3MDL selfTest-LIS3MDL.c

Can you please run it and share the output

[richardp]

Mmmm… Strange...

Can you please upload a photo of the BerryGPS-IMU board?  I want to make sure it isn't missing any chips. I am only interested in the top section where the GPS unit is (Green chip)

Hi, if you are outside with clear access to sky, it should work.

Is the switch on the side in the correct position?  it needs to be set to "int" for internal

[richardp]

The BerryGPS-IMUv4 and the BerryIMUv3 are the only devices compatible with the QWIIC echo system.

we are not familiar with the Artemis boards, however a quick check shows that in theory everything should work.  And yes, the QWIIC connector provides all the power the board needs to function.
If using QWIIC connector only, you will need to solder the two jumpers on the back of the PCB to connect the GPS module to the i2c bus, as shown here

Hi
Is the BerryGPS-IMU outside and have clear access to sky? If it is inside near a window it will not work.

The screenshot you attached is a bit small, I cant see exactly what is happening. Have you disabled the Pi Console on your Pi?

[richardp]

yes it sometimes will if using gpsd.
This is why I think Mark asked you to kill gps and start it manually using gpsmon /dev/serial. Trying it this way would force it to use NMEA by default.

[richardp]

You need to compile the program
gcc -o gyro_accelerometer_tutorial02 -lm gyro_accelerometer_tutorial02.csdl-config --cflagssdl-config --libs-lSDL_image -lSDL_gfx

[richardp]

yes, this is correct. If you want GSM, GPS and IMU, the simplest approach would be to use BerryGPS-GSM and then the BerryIMU. The IC2 pins are broken out on the BerryGPS-GSM and you can connect the BerryIMU to these

[richardp]

Thanks for the heads up, I will get that updated

[richardp]

Yes, you can save all the data into a file onto the Raspberry Pi, you will need to create code for this.

You can connect the BerryGPS-IMU via cables to the Raspberry pi, it doesn't need to sit right on top.
All the pins needed are broken out on the side of the PCB.

The highest supported altitude is 50km

[richardp]

I just noticed you said you connected it via usb.   To access the GPS data, you need to stream it through the GSM module.  see here
