Telelogger sketch, Freematics ONE+ H shows up as online but in the middle of atlantic ocean.
in the middle of the ocean right next to Africa
That's zero coordinates, which usually means no GPS signal. Are you outside with a clear sky visibility for the GPS antenna? Also note that first fix might take 10 minutes or even more in some cases.
Yes my device is outside and with a clear view of the sky. It's debug output is the following which seems to show GPS coordinates are being gathered but I am not positive.

You might show what actually is the raw data in your traccar log.
I can see that my device is showing as having sent coordinates in zeroes, and there also seems to be an IO error of sorts. Output from Traccar logs is the following:

What would be the best way to debug this? I don't understand how the console for the device shows the correct GPS coordinates but then those coordinates don't make it to the Traccar server.
You can probably add some logging on the device to see why it doesn't send location to the server. It must be some configuration.
I installed an older version of the freematics telelogger firmware and Traccar reports the following when the device attempts to send its location:

Thanks I will try that
This should fix the NumberFormatException:
https://github.com/traccar/traccar/commit/fdbd269b9b99de074e2fd9d99d1702620102801b
Thank you for that patch, I'm not sure how to apply the patch to a Traccar container but I will not bother you with those details :)
On the other hand, I added extra logging to the Firmware V5 Telelogger for Freematics and confirmed that the GPS device is attempting to send the following packet to Traccar, I am not sure if this is well formed or not but this is exactly what it is trying to send:
Actual Packet:
UCFLFAYM#0:274036,24:369,20:0;0;0,10:1043307,82:48*BBThat's exactly what's received in Traccar, as you can see in the logs.
In the Traccar logs, I see Traccar receiving:
2023-06-05 01:07:28 INFO: [U65a04d6d] id: UCFLFAYM, time: 2023-06-05 01:07:28, lat: 0.00000, lon: 0.00000, course: 0.0Maybe I am misunderstanding something?
Hi everyone,
I recently received my Freematics One+ H gps tracker onto which I installed the Telelogger sketch and configured it to connect to my cell APN.
The device shows up in Traccar as online (right away which is awesome) however, it seems like actual GPS coordinates are not making it to Traccar since the device shows up in the middle of the ocean right next to Africa.
If anyone has any guidance as to how I can debug this issue I would greatly appreciate it.
