I’am looking for EG912U-GL AT COMMANDS manual where can I found it?
Is there an AT Command to enable SIM1 or SiIM2?
I have sent it to you by email,pls check
Good morning Herbert,
thanks for the documentation, but the problem is not solved, because now when I can select the SIM but then :
AT+CPIN?
+CME ERROR: 10
It seems that the SIM is not inserted, and the module does not enable the voltage on pin USIM1_VDD.
I have connected
USIM1_VDD
USIM1_DATA
USIM1_CLK
USIM1_RST
USIM1_GND
and I left USIM1_DET not connected as indicated in the Hardware design manual.
can you help me to solve the problem?
