No simcard power in EHS5-E | Telit Cinterion IoT Developer Community

January 26, 2017 - 12:26pm, 1624 views


We can't get any communication from EHS5-E to simcard. Module is activated, I can scan network, access GPIO, but no simcard features. There are no voltage on CVCC, no CCLK CCIO signals on EHS5-E pins during trying to access to simcard, for example:


+CME ERROR: SIM not inserted

It seems like something in module is turned off and it even doesn't try to reach simcard. Are there any steps required to activate power of simcard? I don't think it's hardware problem.
