Teltonika FMB910 device creates a new TCP connection every time a packet is sent and closes it after sending. Is this normal operation of the device? I expected the TCP connection to be persistent. If this is not normal, then why can this be?

Hello,

Please check your records settings (GPRS->Records Settings) and Data Acqusition settings:

Checked it out. Sleep mode is disabled, the value of the "Open Link Timeout" parameter is maximum, the sorting of records is "Newest".
 

Each new packet sending begins with establishing a TCP connection and transmitting IMEI, while the device always has a different IP. Maybe you should send logs, screenshots or test code?

Hello.

"Each new packet sending begins with establishing a TCP connection and transmitting IMEI, while the device always has a different IP" - Why schould device IP change every time it sends new packet ?

Please visit our Wiki page for detailed description about codecs:

It's not even about changing the IP, but about multiple connections. I don’t understand why this is happening. There are no problems with parsing the package. There are problems with multiple connection establishment.
