FMT100 Failed to update device info

Trying to configure a FMT100, this will be the 6th one I have done and no issues with the others. SIM is installed and working, FOTA is showing online, bluetooth is paired to computer on the non-LE number. Configurator finds the device and displays it on the first screen, but when clicked on reports: “Failed to update device info. A request to send or receive data was disallowed because the socket had already been shut down in that direction with a previous shutdown call. 388A21301379:0000110100001000800000805f9b34fb”

Have just tried again and the message is now: “Failed to update device info. An invalid argument was supplied. Socket might still be in use, tried to connect 3 times.”


Thank you for reaching out to Teltonika Telematics Community Forum!

What is the version of the configurator you are using?
Please try to use the latest configurator and install the latest firmware for FMT100.
