Hello, I am running latest OS on raspberry Pi but getting fowling error

@onlinegill , Thank you for reporting this. See the link below on the line that you need to add in config.xml:

https://github.com/lmandres/GT06ScannerClient/blob/master/config.xml#L16

Please let me know if this fix works for you.

Hi,

After adding to config
1

now here is output

Hi @onlinegill , are you running this in a GUI environment or from the command line without the graphical user interface?

[lmandres]

I noticed on the output that you are running pygame 2.1.0. Did you install the Python requirements using the following?

pip install -r requirements.txt

In my requirements.txt file, the pygame version is 1.9.6, so I have the feeling that you installed the pygame requirements separately.

I have raspberry pi zero w and I am using headless (no monitor connected to it only ssh)

I could not install with pip install -r requirements.txt because alot of them were giving error that it can't find so I installed individually one by one with latest versions.
All I wanted to plug pi to the car with gps module and connect pi to hotspot wifi and get live tracking on traccar server. I wanted to use esp32 insteadpi due to some coding issue esp32 won't send latitude and longitude information to my traccar server ( that's seprate project)

Sent from phone.
Excuse any typo

[lmandres]

@onlinegill . Thank you. I might have to make changes so that you can run it headless. Let me see what I can fit into my schedule to allow it to run headless.

[lmandres]

Also, I'd be interested in what you have for an ESP32 project as well.

[lmandres]

@onlinegill , actually, try removing the DisplaySettings section in the XML file. You won't get any output, but you should get updates on your Traccar server. You can probably comment out the section like the following:

<!--
    <DisplaySettings>
        <MapsURL>https://c.tile.openstreetmap.org</MapsURL>
        <Zoom>18</Zoom>
        <Magnification>1</Magnification>
    </DisplaySettings>
-->

EDIT: You should probably get output of the GPS information being sent.

[onlinegill]

Let me how to contact you by email so we can talk about esp32. I can send you codes. If esp32 is working then I don't need to use expensive raspberrypi

@onlinegill , email me at its.just.me@juno.com. Thanks.

@onlinegill , was the Pi Zero issue resolved by commenting out the section?

[onlinegill]

@onlinegill , was the Pi Zero issue resolved by commenting out the section?
Yes and no.
Script runs now and I can see GPS information in terminal but it does not post on traccar server

FYI : ESP32 client project is here and its working.

So, looking at your code, my code might not be working because my script is using the GT06 protocol rather than the Traccar REST API.
