EC-20 module CME ERROR 10

Revision: EC20CEFAGR06A10M4G

When I try AT+CPIN? i get +CME ERROR 10 (Sim is not inserted)
I have inserted the sim and it’s working on a phone.
I have tried AT+CFUN=1 to enable the SIM card but it didn’t work.
Any suggestions regarding this.

I am using an embedded linux Nvidia jetpack 4.3
Also can you share how to get logs from the module in linux.

Hi dear,

please try AT+CFUN=1,1, if you are sure about your PCB design

good luck :slight_smile:

Some components were missing from the board will check the code after that. Thanks.

The code works. Thanks.
