Hi,
I’m using an EV02 GPS tracker, and I’ve noticed that when the device loses its GPS signal, Traccar displays the device’s location somewhere near the African continent. During these times, the device sends some unusual or malformed messages to the server.
I reviewed the messages and tried interpreting them using the GT06 protocol, but I couldn’t derive any meaningful results.
Interestingly, when the device regains GPS signal, it sends proper and interpretable messages again. This leads me to suspect that the protocol might be incorrect, or that the device is switching to a different message format when GPS is unavailable.
Could you please help me understand the meaning of these messages or advise whether the correct protocol is being used?

Do you have the protocol documentation from your device?
Then I don't think anything can be done here. This is definitely not GT06 protocol.
Hi Ahmet, where did you buy the device?
I bought it from Amazon. I think it is a Chinese clone of EV02.
Hi,
I’m using an EV02 GPS tracker, and I’ve noticed that when the device loses its GPS signal, Traccar displays the device’s location somewhere near the African continent. During these times, the device sends some unusual or malformed messages to the server.
I reviewed the messages and tried interpreting them using the GT06 protocol, but I couldn’t derive any meaningful results.
Interestingly, when the device regains GPS signal, it sends proper and interpretable messages again. This leads me to suspect that the protocol might be incorrect, or that the device is switching to a different message format when GPS is unavailable.
Could you please help me understand the meaning of these messages or advise whether the correct protocol is being used?
