we have planned to use your EM7455 cellular modules.
but our SIM card connector does not have any sim detect functionality, so can we just leave the SIM DETECT pin in the module floating.
the module datasheet says,
if SIM not inserted connect the SIM detect pin to gnd
if SIM is inserted keep the detect pin floating(it has an internal pull up)
so if i keep the SIM detect pin flating it will always be in SIM detect state so will it function properly?
if it will not work this way can i give a module reset to make it work properly?
