Square Tracker L for LoRaWAN: quick start

From the opened box to a working sensor on one page. The full manual has the details, the settings and the troubleshooting.

Full manual Product page Product sheet (PDF)

Square Tracker L tells you where your assets are indoors: it scans the Wi-Fi access points around it when it starts or stops moving, and a cloud service such as Yggio turns the scans into positions. Its 6,000 mAh battery is made for frequent positions.

In the box

  • Square Tracker L, with the adhesive already on the back
  • The keys (DevEUI and AppKey) come with the delivery information

You need

  • A LoRaWAN gateway within range, online, and an account on a LoRaWAN network server with the gateway added
  • The sensor’s DevEUI and AppKey. The JoinEUI is 70B3D52C0001D4C3
  • A phone with NFC, to start the sensor. Android is recommended; an iPhone needs an NFC reading app
  • A payload decoder for Sensative VSM sensors, and a cloud service that supports Wi-Fi positioning, for example Yggio. Without it the scans give no position
  • The optional Hugin NFC app needs an Android phone with NFC and GPS, and an Yggio user account, with the sensor registered to your organisation

From box to ready

1

Register the sensor in the network server

Add a new end device: OTAA, MAC version 1.0.4, regional parameters RP002-1.0.3, max EIRP 14 dBm, and your frequency plan. Enter the DevEUI, the AppKey and the JoinEUI.

Done when: the device is listed, waiting for its first join.
2

Join the network with NFC

Switch NFC on and take off the phone case. Hold the phone over the lower left corner of the front and keep it still for about 5 seconds.

Done when: the network server shows the join, usually within two minutes.
Register the sensor, hold a phone with NFC over the lower left corner, and it joins within about two minutes
The NFC field is at the lower left of the front.
3

Check the signal where it will sit

Put the sensor where it will be mounted and look at its messages in the network server.

Done when: the link carries SF9 or better: SNR above −5 dB and RSSI above −115 dBm.
4

Mount it on the asset

Clean the surface with a 50:50 mixture of isopropyl alcohol and water and let it dry. Peel the film off the adhesive and press the sensor firmly in place, with the NFC corner still reachable.

Metal is fine, but avoid closed metal enclosures, such as a shut steel cabinet: they block both the radio and Wi-Fi.
5

Test

Move the asset, or the sensor, and then leave it still. By default it scans when it starts or stops moving, and once a day while still.

Done when: about a minute after the movement starts, and again after it stops, Wi-Fi scans arrive and the cloud service turns them into a position.
