Hello,

I am trying to make basic call with EM9191 module, it seems module is not receiving any RF energy.  
I noticed, SIM\_PWR is 0V,  
and SIM is not detected by AT+CIN? command.

Is there any setup of command we need to run to Configure the EM9191 module ?  
Do we need any command to enable USIM\_PWR ?

Firmware : SWIX55C\_03.09.06.00.

Thanks

I don’t see problem.  
You can try the same FW and setting as mine:

Hello,

I tried below setting,  
still I am getting SIM error.

I measured via oscilloscope as well, there is no voltage on USIM\_PWR (Pin 36)  
Is there any command to enable or test USIM\_PWR ?

Hello,

Can you suggest, Is there any dependency for SIM\_PWR to generate from Module ?

1. Is there any GPIO dependency that must be drive low or high ?
2. Do we need to run any command to enable SIM\_PWR ?

Thanks

I don’t run any extra command before for enabling SIM interface…

You might need to read the SIM section in PTS:

Hello,

The SIM detect signal logic was reverse in my design,  
It is working after disconnecting the Signal.  
Thanks for your help.

Thanks
