Hi,

I'm getting a very weird behaviour and have no more ideas what could be the problem:

the card starts up as it should (revision 1529B01SIM7000E)
AP is set to 'telia'
I'm sending command 'f' which is fona.getIMEI(imei);
first time it returns ok
I'm sending command 'f' which is fona.getIMEI(imei);
... its seems the card shuts down??? cause it won't respond to any command afterwards

Is the card shutting down after a successful command?
Any idea what I'm doing wrong?

Regards, Akos

Could it be a firmware issue?

I noticed that the firmware is '1529B01SIM7000E', which is a bit confusing, considering the list here.

On that page the latest 'E' firmware seems to be '1351B08SIM7000E.rar'.
There is a '1529B01SIM7000G.rar' which is a "G" (all the previous versions combined into a single module).

The "G" is 4 years old, while the "E" is 3 years old, which one I shall have???

Regards, Akos

Unfortunately I can't really help with that because I'm not familiar with their hardware.
