Hi,
This code: ` // libraries
include
// PIN Number
define PINNUMBER "2355"
// initialize the library instance GSM provider; // include a 'true' parameter to enable debugging GSMScanner scannerNetworks; GSMModem modem;
// Save data variables String IMEI = "";
// serial monitor result messages String errortext = "ERROR";
void setup() { // initialize serial communications and wait for port to open: Serial.begin(9600);
while (!Serial) { ; // wait for serial port to connect. Needed for Leonardo only }
Serial.println("GSM networks scanner"); scannerNetworks.begin();
// connection state boolean notConnected = true;
// Start GSM shield // If your SIM has PIN, pass it as a parameter of begin() in quotes while (notConnected) { if (provider.begin(PINNUMBER) == GSM_READY) { notConnected = false; } else { Serial.println("Not connected"); delay(1000); } }
// get modem parameters // IMEI, modem unique identifier Serial.print("Modem IMEI: "); IMEI = modem.getIMEI(); IMEI.replace("\n", ""); if (IMEI != NULL) { Serial.println(IMEI); } }
void loop() { // scan for existing networks, displays a list of networks Serial.println("Scanning available networks. May take some seconds."); Serial.println(scannerNetworks.readNetworks());
// currently connected carrier Serial.print("Current carrier: "); Serial.println(scannerNetworks.getCurrentCarrier());

I have a bridge with pin 2 and 10..
