Hi everyone.
I am using an arduino uno board with GSM shield 2 (just bought it).
I have external supply from jack 12v and 1500mA working fine.
The sim card is working fine.
I use arduino IDE 1.8.5.
I use the code provided by getting started example:
// import the GSM library
#include <GSM.h>
// PIN Number
#define PINNUMBER "2103"
// initialize the library instance
GSM gsmAccess(true); // include a 'true' parameter for debug enabled
GSMScanner scannerNetworks;
GSMModem modemTest;
// Save data variables
String IMEI = "";
// serial monitor result messages
String errortext = "ERROR";
void setup()
{
// initialize serial communications
Serial.begin(9600);
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(gsmAccess.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 = modemTest.getIMEI();
IMEI.replace("\n","");
if(IMEI != NULL)
Serial.println(IMEI);
// currently connected carrier
Serial.print("Current carrier: ");
Serial.println(scannerNetworks.getCurrentCarrier());
// returns strength and ber
// signal strength in 0-31 scale. 31 means power > 51dBm
// BER is the Bit Error Rate. 0-7 scale. 99=not detectable
Serial.print("Signal Strength: ");
Serial.print(scannerNetworks.getSignalStrength());
Serial.println(" [0-31]");
}
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());
// returns strength and ber
// signal strength in 0-31 scale. 31 means power > 51dBm
// BER is the Bit Error Rate. 0-7 scale. 99=not detectable
Serial.print("Signal Strength: ");
Serial.print(scannerNetworks.getSignalStrength());
Serial.println(" [0-31]");
}
I get the following result on the serial monitor:
GSM networks scanner
Modem IMEI: 0
Current carrier: 0
Signal Strength: [0-31]
Scanning available networks. May take some seconds.
Current carrier: 0
Signal Strength: [0-31]
Scanning available networks. May take some seconds.
It looks like I can't connect to my modem. Any idea why ?
Greetings,
