I have an FMC125 connected to a Dualcam (RS232.) Worked fine for few days then it stopped transmitting to my server. Tried sms command `cpureset` but it doesn't respond to any sms commands. Confirmed sim has data and it rings when I call it. Is there anything else I can try to revive it remotely?
I was given firmware FMB.Ver.03.27.13.Rev.367_ID1 by Teltonika support (had to go through about 4 versions before it would work with Dualcam.)
