Useful Resources • Slack Community : https://sigfoxbuilders.herokuapp.com/ • Sigfox Build (documentation): http://build.sigfox.com • Arduino MKRFOX: https://www.arduino.cc/en/Main.ArduinoBoardMKRFox1200
- 14. Getting started with the Arduino MKRFOX
- 15. Using the Arduino Online IDE Create an account on https://create.arduino.cc Follow the instructions to install the browser plugin
- 16. Board will show up in the menu
- 17. Retrieve your board information Copy the code from http://github.com/sigfox/mkrfox-init
- 18. Upload to your board & open the monitor
- 19. Online onboarding https://buy.sigfox.com/activate Country: France Enter your device credentials Enter your personal information
- 20. Find your way in the Sigfox Backend The Sigfox Cloud is organized around 3 concepts : • Group : Contract & User rights • Device Type : Family of devices sharing the same properties • Device : A unique device
- 21. List of your device types
- 23. Devices associated to a device type
- 25. Hello World
- 26. Hello World Copy/paste from Github : • https://github.com/nicolsc/mkrfox-hello-world Upload to your board using the Arduino Editor or IDE
- 27. Message received ? http://backend.sigfox.com Navigate to the devices menu in the top bar Click on the ID of your device Enter the messages menu from the left navigation column
- 29. They turn into actions and insights through the customer IT They can be analyzed on Big Data analytics platforms Partners with specific applications for your business Interoperability with top-tier Big Data platforms Standard and easy access They are stored in the sigfox cloud Get the data (pull / push) 44
- 30. Callback setup Device Type menu Click on your device type name Enter the Callbacks menu Select new default callback
- 35. Callback status In the Devices > Messages panel, you have a indicator of the callback status (an arrow) Black : in progress Green : Callback OK Red : Callback KO (at least one of the callbacks failed) Click the arrow to display details.
- 37. Get real world data https://github.com/nicolsc/mkrfox-send- internal-temperature
- 39. Demo platform Register on : https://try.iotagency.sigfox.com Create a new callback following the API documentation Play around !
- 40. Geolocation
- 41. Geoloc callback Simply create a SERVICE > GEOLOC callback, and receive latitude + longitude + accuracy
- 42. Geolocation Callback Create a new Service > Geoloc callback Use following URL to center the map: https://maps.googleapis.com/m aps/api/staticmap?center={lat},{ lng}&zoom=13&scale=1&size=6 00x300&maptype=roadmap&for mat=png&visual_refresh=true
- 44. Bi-directional communication Requested by the device to the network Static downlink message size of 8 bytes Agreed frequency of downlink ✓ ✓ ✓
- 45. Downlink Callback setup Automatic callback: Device Type > Informations > Edit Set Downlink mode to DIRECT Enter an 8 bytes value
- 48. Sample code Simple change SigFox.endPacket(); to SigFox.endPacket(true); This will request a response from the network
- 49. Handle the response https://github.com/nicolsc/mkrfox-downlink void loop(){ while (SigFox.available()) { Serial.print("0x"); Serial.println(SigFox.read(), HEX); } }
- 50. Frame parsing
- 51. Sigfox payload display feature Using a « simple » grammar, you can ask Sigfox to parse your incoming data This is done at the device type level
- 54. Parsing the Hello World sample Modify the sketch to send 3 values in a same message short valA = 7700; short valB = 128; float valC = 654.32; SigFox.beginPacket(); SigFox.write(valA); SigFox.write(valB); SigFox.write(valC); SigFox.endPacket();
- 55. Set a custom grammar valA & valB are shorts : 16 bits valC is a 32 bits float valA::uint:16:little-endian valB::uint:16:little-endian valC::float:32:little-endian
