Just checked version from 2 units and they are:
EC25EUXGAR08A13M1G_20.200.20.200
EC25EUXGAR08A09M1G_20.003.20.003
Problem is that randomly we lose all control to these modules and they appear to Windows Device manager list of serial ports for some seconds and then disappearing again some seconds and then appearing again…
Not sure if module problem or PC problem.
I have sent the new driver to you,you try again
How about firmware tools?
I have upgraded approx 300 older units replacing GSM modules.
Version are unknown and would like to have latest possible.
I have sent the new firmware and update tool to you,you try again
