Maybe getSignalStrength was invoked before network being registered. Try to wait for network registration.
while(!gprs.isNetworkRegistered())
{
delay(1000);
Serial.println("Network has not registered yet!");
}
getSignalStrength(buffer) command is returning a 0 value despite a return of 15 from the AT+CSQ when manually entered
