Good day.
I have an arduino Uno R3 and a GSM shield 2.
The uno is connected to a 5V dc wall adaptor. The shield is connected to the uno.
I cannot shut the shield down using shutdown(); Below my code and serial output.
Any advice will be greatly appreciated
------MyCode-----------------------------
#include <GSM.h>
#define PINNUMBER ""
GSM gsm(true); // include a 'true' parameter for debug enabled
void setup()
{
Serial.begin((9600);
boolean Connected = false;
// Start GSM shield
while(!Connected)
{
if(gsm.begin(PINNUMBER)==GSM_READY) {
Connected = true;
Serial.println("GSM initialized");
} else
{
Serial.println("Not connected");
delay(1000);
}
}
boolean res = gsm.shutdown();
delay(5000);
while(Connected) {
if(res) {
Serial.println("GSM disconnected");
Connected = false;
} else {
Serial.println("GSM still on");
delay(1000);
}
}
}
void loop()
{
}
------Serial monitor output--------------
