Hello,
I am working on a circuit in which the GND ping of GSM module connects electrically to phase line of 220V AC power line !
the power supply of the circuit is supplied by a SMPS, but the connection of gnd to phase line is done because i am measuring the phase line current through a shunt resistor.
now, does it make any problem in GSM module function ?
