Hello i hope someone of you can help me.
I build my WiSMo board, i used DALC208SC6 and ESDA6V1SC6 (as is in the PDF document for desing) for interfacing SIM. I connect the device, then power ON. I used Discovery Tool for test it, for here all is ok, but suddenly it appears that SIM is no connected, so i cannot do anymore… (see pictures below)
Any attempt of use my device results in +CMS ERROR 310 (Not SIM inserted).
Is there any power source problem? I used a battery from a Nokia Cell. (3.6V nominal, full charged).
Is there other kind of problem?
Thanks in advance!
