I am receiving incorrect coordinates that are placing me in the sea. SIGFOX

jojan2 years ago

I am experiencing issues with the coordinates from a Sigfox device, which is currently showing a location in the sea. This problem arose about three days ago, as the coordinates were previously accurate. I have verified the string, and the coordinates are correct when I check them independently. The GPS is in POST format on port 5055.

To obtain the correct coordinates in another program that I use to decode data strings, I am using the following format:

{
"device": "{device}",
"time": "{time}", "snr":"{snr}",
"station": "{station}",
"data": "{data}",
"rssi": "{rssi}",
"seqNumber": "{seqNumber}",
"cliente": "prueba"
}

this are the correct cordenatees
Latitude (Hex): 4192F01D
Longitude (Hex): C2C2B939
Latitude: 18.36724281311
Longitude: -97.361763000488
However, the platform I am using (Traccar 5) is converting them to:

Latitude: -25.885056°
Longitude: -117.841866°

Any assistance in resolving this issue would be greatly appreciated.

  1. I recommend upgrading to the latest version.
  2. Provide protocol documentation.
  3. Provide the full message sample.

Hi, Is it possible to move the Sigfox to the Suntech GPS port? Or would it still not send correctly? I asked this since its protocol is similar to that of the 30u model, or would that difference prevent it from giving me its position correctly?

Im using the por 5055

Not sure I understand the question. You need to use the protocol that matches the format.

Hi there,

I apologize for my English not being perfect im new on this lenguaje . What I'm trying to say is that since the Sigfox device reporting to me at sea is a Suntech device, I can use the Suntech port instead of the current OSMAND protocol port. The current port is 5055, and I wanted to see if I could move it to 5011 to fix the problem I'm having.

The sample you provided earlier is definitely not OsmAnd protocol, do yes, you should try and find the right port.
