sim not detected after upgrading to 7.51

Hello,

After upgrading FXT009 to fw 7.51, the SIM is not detected!
If I activate WIND, I got the sequence 13, 0, 7 .
The original fw was 7.46 and if I downgrade to 7.46 the SIM is detected again.

Do any one see this behaviour?
Is this a known issue?

thank you

Hi,

What is the error being observed,on inserting the SIM except +WIND indications?

Please enable the CME error using AT+CMEE=1 and observe the error,
What is the resposnse of AT+CPIN command?
Did you try with resetting the module and inserting an removing the SIM again?What are the WIND indications being observed on doing the same.

Also,is the problem seen with other firmwares i.e. 7.50,7.47 or the lower versions like 7.44 and 7.45.

Thanks.

Hello,

i have the same problem. Is there meanwhile a solution.

Hello again,

my case ist a bit diffrent. I’ve also updated to Version 7.51 and have the problem with not detecting the SIM.
The difference is that downgrading to 7.47.4 and also 7.47.0 does not solve the problem. This is the case with two different SIMs and also two identically Hardware. So i’ve tried 4 combinations.

Thanks
