Topic: SIM not present or wrong PIN (no retries) (Read 574 times) previous topic - next topic



I am using Connection Handler Github link to get connected to GSM network via MKR GSM 1400. From time to time when I restart or reupload the sketch I am getting error "SIM not present or wrong PIN" attaching screenshot.

When I restart the unit (reset button) or reupload the sketch connection is successful. Looks to me that function just finish and never continue "void GSMConnectionHandler::init()" Arduino_GSMConnectionHandler.cpp

  • Does this means in default settings there is no 2nd, 3rd etc. retry ?
  • If so, is there any settings to set it up the way it will try to reconnect ?
