Which AT command to disable SIMPRES?


#1

Does someone know how to disable the SIMPRES(GPIO18) pin?
I think the solution is in the document “AT Commands Interface Guide For Open AT® Firmware v7.1”, Volume 4, page 104 and further. But I still didn’t found the solution there.
If the SIMPRES/GPIO18/INT8 pin is in its normal state, the pin is used as SIMPRES, but the SIM card holder I use does not have a SIM card presence contact, so the pin stays low and the Open AT firmware refuses to read the SIM card…

Does AT+WFM=0,”SIMREMOVE” help :question:

Yes, that’s the solution. Thanks.
