What do you see in the logs now?
Nothing usable.

Can you send it in text? This doesn't look like encrypted data to me.
Not possible now
I think this is a encrypted string.

That's very different format from what you provided earlier. Very confusing.
This is from todays log
Hi,
I am looking for firmware for the Eview EV-07BX tracker.
The device was supplied by a company that uses its own app and platform. Because of this, the Eview protocol appears to be encrypted, and it sends unreadable data to a Traccar server.
I am therefore looking for alternative firmware that is compatible with Traccar and allows the tracker to send readable data.
