Devices going constantly offline and online
Have you checked logs?
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.
This is what I am getting from the logs

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.
These are samples of what I am getting . No connected related logs anywhere.

Hi, I am kinda out of ideas here. Any inputs are welcome. Any other thing that i can do to debug?
I already pointed what you should be looking for in the log.
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
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?

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
