The only strange thing with this WiSOL module is that it responds with “ERROR: parse error” at the usual “AT” command.

A simple test code that sends some data to the network respecting the constraints:


/*
 Sigfox Module Test Unit
 */

int button = 2;
int led = 13;

void setup() {
// WiSOL works on 9600:
  Serial.begin(9600);
// some basic LED debug info
  pinMode(button, INPUT);
  pinMode(led, OUTPUT);
// more to go for the receive function
// add ",1" for the downlink frame 
}

void loop() {
   int buttonState = digitalRead(button);
      if (buttonState == LOW){
        Serial.println("AT$SF=000011110000");
        // some basic LED debug info
        digitalWrite(led, HIGH);
        delay(800);
        digitalWrite(led, LOW);
        delay(200);
        digitalWrite(led, HIGH);
        delay(800);
        digitalWrite(led, LOW);
        delay(200);
        // obey to the max 1 msg every 10 min rule 
        delay(600000);
  }
else {
        // basic LED debug info
        digitalWrite(led, HIGH);
        delay(50);
        digitalWrite(led, LOW);
        delay(1000);
        digitalWrite(led, HIGH);
        delay(50);
        digitalWrite(led, LOW);
        delay(1000);
        digitalWrite(led, HIGH);
        delay(50);
        digitalWrite(led, LOW);
        delay(1000);
        digitalWrite(led, HIGH);
        delay(50);
        digitalWrite(led, LOW);
        delay(1000);
        
 
  delay(40000);
  }  
}
