We have six FMB001 car trackers which have been up and running between 2-3 months now. They have all been updated to 3.18.16 firmware.
They connect to our own Traccar system. Recently one of them have became unresponsive.
It would not respond to SMS commands and when I removed it from the vehicle and connected to my laptop it was not visible as a USB device, nor to the Teltonika Configurator software. Only after disconnecting the internal battery and reconnecting it did it come back to life.
Can anyone provide suggestions as to how to prevent this into the future or the best course of action? It would severely impact our tracking systems if this is going to become a regular occurrence, as well as the inevitable loss of data.
I should note that another of the trackers has also been down for several days now, but until the vehicle is back I cannot see if it is the same problem.
The last couple of entries in the log don't really seem to indicate much:

Thanks in advance,
