Ok, the LED on Pin 13 should turn on, not just blink.
I am not using the tail log so can't tell you what I see, but if you open the serial monitor you should see the payload arrive.
To access the serial monitor select the small magnifying glass icon on the top, right of the Arduino IDE screen. A window with white background should appear. Now, go to the IoT dashboard, select the menu then pick Control, then the name of your device (mine is called Interactio_Hub), then the Component (mine is called power) then Parameter Name (LED 0,1) and the Value (0 or 1) then Transport Type (mqtt). Once these are all selected then hit Add Action and last select Send all valid actions.
Now watch the serial monitor - it seems to take between 3-4 seconds and you should see the text appear (I have a few in here and I have extra printlns in the code, but the line you are looking for starts with "Good JSON Command from Server...":
and the LED should come on (and stay on). If that's not working I'm not sure what you should do, other than try rebooting everything.
Hope it helps - David
Jakub - one thing I just thought of - make sure you change the PIN in my code to 13 (I used 8 because I am running a grove expansion board and have an external LED plugged into D8). Yours should also say powerswitch not power and should look like this with just the default Edison & Arduino:
if (strcmp(value->valuestring, "1")) { //changed to LED.v1.0 from light
Serial.println("continue, now after strcmp command LED line in loop");
Serial.println("Light Off!");
pinMode(13, OUTPUT);
digitalWrite(13, 0); //should false be changed to 0?
}
// if (strcmp(command->valuestring, "LED") == 0 && strcmp(value->valuestring, "1") == 0) {
if (strcmp(value->valuestring, "0")) {
Serial.println("Light on!");
pinMode(13, OUTPUT);
digitalWrite(13, 1);
Also, I verified the latest Example code that Brian mentioned above. it ALMOST works! I had to comment out the first line in the nested IF loop like this (and again mine is set for pin 8 not 13):
