Sigfox was created in 2010 and is a recognized global pioneer and leader in the device connectivity sector that is already disrupting business models. The ambition of Sigfox, embodied in the slogan "Make Things Come Alive," is to give a voice to the physical world around us and to allow these millions and one day billions of objects to play a role in economic and social development.

One way that Sigfox is setting itself apart as a is with its geolocation services called Spot'it - a very low cost mechanism to track a large of assets around the world, without needing GPS. Spot'it is a new asset tracking service that allows any Sigfox modules to become a geolocation service, without need to upgrade the hardware of software. 

Main benefits we can highlight: 

  • The lowest cost geolocation service for IoT

Spot'it doesn't require hardware or additional updates, and the device doesn't have to transmit more messages, which means that there is no impact on the operating cost for consumer's solution.

  • Low power consumption 

Spot'it doesn't use GPS technology (which consume a lot of energy), nor does it require any additional processing or energy consumption than a standard Sigfox device currently utelizes.

  •  Support for a global network 

 Spot'it represents the first geolocation service for devices connected to IoT worldwide. This simplifies the global management of the supply chain: once a device is registered in the Sigfox Cloud, the geolocation system will be available in all territories that the network is present.

  • Unlike the traditional GPS system, Sigfox Spot'it works both indoors and outdoors. 

NOTE: To learn more information about Sigfox's Geolocations, reference this Sigfox press release on Spot'it.

Setting up Geolocation Services

Using this guide you will learn how to setup your Sigfox service callback to send the location of your device to the Ubidots cloud to display and locate your asset in real-time.

Requirements

  • Sigfox Service Callback 
  • A Sigfox device already configured 
  • Ubidots account

Sigfox Service Callback setup 

IMPORTANT NOTE: this guide assumes that the device is already registered and is already sending data to the Sigfox backend. If your device is not yet configured, reference to these articles below to complete your device setup. 

1.- With your devices connected to Sigfox, it is now time to set up the service callback. Go to the Device section and click on the registered device:

 2.- Next, verify your device information and select "CALLBACKS" from the menu on the left of the page. See below for visual resources:

Sigfox callbacks allow you to report data to an external system like Ubidots. In this case we are going to configure the geolocation service to the callback to send the position of the device to Ubidots. 

3.- Setup a service callback to Ubidots API, using these parameters:

  • Type: SERVICE  - GEOLOC 
  • Channel:  URL 
  • URL pattern:  http://things.ubidots.com/api/v1.6/devices/{device}
  • Use  HTTP Method: POST
  • Send SNI: Disable
  • Headers: x-auth-token - {Your_Ubidots_Token}
  • Content Type: application/json  
  • Body:
{
  "snr" : "{snr}",
  "avgSnr" : "{avgSnr}",
  "position":{"value":0,"context":{"lat":"{lat}","lng":"{lng}"}, "radius": {radius}}
}

NOTE: If you don't how find your Ubidots TOKEN, please reference the article below. 

After configuring the callback, it will look similar to ours below:

4.- Once you have confirmed the callback as accurate, press "OK". Your callback is now ready and enabled to post data to the Ubidots Cloud.

Posting locations to Ubidots

Now that the service callback is configured, and your device is sending data to the Sigfox backend, it will automatically create a new device in your Ubidots account with the ID of your Sigfox device as the "name." If you look inside the device you will see the variables sent, and inside the "position" variable you will see the coordinates of the device in the context. 

1.- Once data messages are received from Sigfox in Ubidots, you will see something like the image below when looking at your devices in the Device tab:  

As you can see in the image above and your own dashboard, the position of the device has automatically been assigned.

Pro application - Create a Map Widget. Ubidots helps tracking your devices using the Maps Widgets. To learn more about maps and how to create your own applications, check out Ubidots Help Center for additional resources and instructions. 

Result

Thanks to the Service Callback from Sigfox we can implement a low cost and low power consumption application that is supported almost in all the world, no matter if the device is indoors or out! 

Now it is time to create a dashboard and control/manage the variables of your Sigfox device. To learn more about Ubidots widgets and events, check out these video tutorials.

Happy hacking :)
