I got my new TMT250 yesterday and have downloaded and installed the COM port driver and Configurator, as described in the manual.
When I try to connect the TMT250 to the compluter, it connects, but after a few seconds it disconnects. I have to reboot the TMT250 to connect again. But after some seconds it disconnects again. And this continues.
When the device connects I see that the firmware version is "55.01.02 Rev:01"
I have downloaded Teltonika.Configurator_1.6.11_R.30.exe, which is the latest. Maybe this is the wrong version of Configurator together with the firmware?
When I try to save a configuration file to the device, I get the error message:
"Failed to save configuration: Could not write to serial port - it is not connected"
When I try to update the firmware to FMB.Ver.55.01.02.Rev.01.e.xim, whis is the latest version, I get error message:
"Failed to update"
After it disconnects I get the following message when I try to see the device info:
"Failed to update device info. Failed to get info"
What can be wrong when I get these messages and the device always disconnects after a few seconds?
If I have wrong versions of the software I hope you will tell me where to find the correct versions.
