Devices going constantly offline and online

Enirh10 months ago

Hi,

I am trying to use a few GT800 devices with Traccar. However, I haven't been able to bring them properly online. The device comes online and becomes offline every 1 minute or so. I haven't this issue before. All other devices are working fine. Any help would be appreciated

Have you checked logs?

Enirh10 months ago

Yes. The device is reporting data. Some packets are filters due to the zero filter.

Also, I have a few other devices running on the gt06 protocol. The problem isn't replicated for those.

We'll, you need to look for connection related events in the log.

One more thing, since the positions are getting filtered, Initially I thought the device is failing to get coordinates from the GPS receiver. However, when I am sending SMS commands the device is responding with the correct location. Can there be a protocol variation? GT800 is an official device from Concoxx and not a clone if I understand correctly.

Any connection related information is still omitted in your log.

That is all that I am getting in the logs. If you need me to search with a specific string or enable any specific log level, do tell me that. Thanks.

Hi
I have mt600 since two years and working good
But now it offline since one week. I dont why, can any one help me to solve the problem

Enirh10 months ago

Hi Anton, I understand what you are saying. But I am unable to find any data related to connection. I am using the default loglevel.

I can give you a dump of the entire if you want. The devices are going online n offline with every ping with the device. I have filtered the file with the device imei, and also IP. But unfortunately haven't been able to get anything concrete.

I have even tried to isolate the device to a new server. The same behavior is observed.

Ok. I searched with the random hex ( is that a session of some sort ) and found the following. Does this help?
