First Configuration with MKR FOX 1200

Learn how to configure the MKR FOX 1200 to work with the SigFox network.

This example for a MKR FOX 1200 device allows you to setup the SigFox's backend for your board.

Hardware Required

Circuit

Connect the antenna to the MKR FOX 1200 board as shown in the image below.

Code

In setup() the Serial is initialized. This will allow you to insert your first SigFox message and to get the information you need to configure the SigFox's backend. Since the MKRFox1200 doesn't have an auto reset function associated to the Serial monitor opening, a Serial while is present. We also check that the SigFox module is present and can be used.

void setup() { Serial.begin(9600); while(!Serial) {}; if (!SigFox.begin()) { Serial.println("Shield error or not present!"); return; }

After this, we can read our ID and PAC that you have to use to register your board.

String version = SigFox.SigVersion(); String ID = SigFox.ID(); String PAC = SigFox.PAC(); // Display module information Serial.println("MKRFox1200 Sigfox first configuration"); Serial.println("SigFox FW version " + version); Serial.println("ID = " + ID); Serial.println("PAC = " + PAC); Serial.println(""); Serial.print("Module temperature: "); Serial.println(SigFox.temperatureInternal()); Serial.println("Register your board on https://backend.sigfox.com/activate with provided ID and PAC"); delay(100); // Send the module to the deepest sleep SigFox.end();

Register Your Board

To register you board you have to navigate to the SigFox backend. This is an one time registration process, needed once for every MKR FOX 1200 you own.

step 1, registration

Select the country where the user is residing or using it right now

After that, enter your ID and PAC number which was shown on the serial monitor after uploading the sketch the FIRST CONFIG.

Now you can check the incoming and outgoing messages from the sigfox back end.

Input your credentials to get to the Sigfox portal home page.

Now we have to make sure that our Downlink mode is set to Direct and not Callback.

Click on the Device type and then click on the Keep Alive and click Edit.

So, put Downlink mode to Direct to receive messages back and forth.

Now you can go back to the main Sigfox portal page and click on the Device on Top left, then click on the ID as shown in the image below.

Select the messages item on the left menu bar.

In this page you can see the messages. If it is sent properly, then you can see the green call back otherwise, you can see callback as a red arrow

When the configuration for callback is done properly, you can send your first message! If your message is correctly delivered you will get a response from the server similar to:

Serial monitor, positive server response
Serial monitor, positive server response

Otherwise an error message will be printed on the serial monitor

Serial monitor, error message response
