Each one of the BLE nodes must be configured properly to communicate with the Indoor Tracking server. These are the 3 things that need to be configured:

1. the Internet connection that will be used by the BLE nodes to communicate with the Indoor Tracking server. Inside this page you can find the specifications of the Internet connection.
2. the endpoint of the MQTT broker/client.
3. the transmission frequency (a.k.a. the Request interval).

The configuration of the BLE nodes can be done using one of the following methods (in order of preference).

Using a desktop application for Windows/Ubuntu

1. Turn on the BLE node that you want to configure and connect it to a network using an Ethernet cable.
2. Install the configuration application on a computer that is connected to the same network that will be used by the BLE node:
   • Configuration app for Windows 64-bit
   • Configuration App for Ubuntu
3. Open the application.
4. Click on the RELOAD button in the top-left corner of the application.
5. Select the BLE node to be configured from the drop-down menu.
6. From the Dashboard tab take note of the MAC address of this device.
7. Click on the Application tab. Set these parameters:
   • Connection Type: MQTT Client
   • Host:  its.stura.io
   • Port: 1883
   • Publish Topic: beacons (please note that even though the value is shown by default, you need to actually type it in the text field!)
   • Request Interval: 3
   • Advertising Filter: iBeacon Only
8. Click on Save.
9. Click on the Advanced tab and click on Restart.

Repeat the configuration for all the nodes starting from Step 3 and do not touch any other parameter! DO NOT upgrade the firmware on the BLE nodes.

Using an API POST call

1. Turn on the BLE node that you want to configure and connect it to the network using an Ethernet cable.
2. Open your browser and type the address of the router.
   • on Windows the address is the one shown under the “Default Gateway” when the command “ipconfig” is typed inside a Windows shell.
3. Inside the router settings look for the DHCP table (the list of devices connected to your Wi-Fi router and the IP assigned to each one of them).
   • sometimes this table is called “Attached devices“.
4. Take note of the IP address assigned to the BLE node (the MAC address of the BLE node is the one printed on the side of the node).
5. Install a REST client (like cURL) on a computer connected to the same network that will be used by the BLE node and issue the following POST call from the shell:
   curl http://IP address/config -d "conn-type=3&mqtt-host=its.stura.io&mqtt-port=1883&mqtt-topic=beacons&req-int=3&min-rssi=-127&adv-filter=1&dup-filter=0" -X POST -H "Content-Type: application/x-www-form-urlencoded; charset=UTF-8"

Repeat the configuration for all the nodes starting from Step 1.
