Frequently Asked Questions (FAQs)

[1] My device is able to communicate with the LoRa Edge Config app so it is working, but it is not joining the network, what might be the problem?

There are several things to verify to ensure the device connects and reports to the network. First, make sure that you gateway is powered and connected to the Actility network (be sure you have run and verified all of the steps in the section Create the Gateway on Your Account above). After you have verified the gateway is connected to the network, make sure you have claimed your device on the LoRa Cloud™ Device Join Service (see section Claiming a device above). After verifying that the device has been claimed, verify that the traffic is arriving at the Actility website. Check the device settings have been properly set in the section Create the Tracker Device above. If the device is sending JOIN messages but not DATA messages, double-check the values in the section Claiming a device above. If there is no traffic coming from the device at all, no DATA or JOIN messages, verify that the LR1110 Tracker is not in “Airplane Mode” by going through the section Setup Your Tracker above. Following these instructions should resolve most setup and configuration issues.

[2] How do I turn on the LoRa Edge Tracker device?

The device is always-on and is shipped in “Airplane mode” and will not transmit or receive data until the LoRa Edge Config app is used to take it out of that mode. See the section above called Setup Your Tracker for instructions to take the LoRa Edge Tracker out of Airplane mode.

[3] How do I connect the provided gateway to Actility?

Follow the instructions in the section Create the Gateway on Your Account above.

[4] What is “GNSS” and how is it related to GPS?

GNSS stands for Global Navigation Satellite System and is a generic term for satellite-based radio frequency positioning. Examples of GNSS constellations are GLONASS (operated by the Russian Federation), Beidou (operated by China), Galileo (operated by the European Union), and GPS (operated by the United States). GPS stands for the Global Positioning System and is often used interchangeably with GNSS. In many cases today, “GPS receivers” include the capabilities from multiple constellations and are technically “GNSS receivers”. The trackers in the LoRa Edge Tracker Evaluation Kit have the ability to receive signals from the GPS and Beidou constellations of satellites.

[5] About how long from the time a device is activated will it take to see data on the dashboard?

If your gateway is connected and functioning, the first message should appear on the TagoIO dashboard within five minutes. Note: If testing indoors, the device may not show on the “Device Tracking” tab until it is outdoors and it can get a GPS fix.

[6] What happens when a device is active but a gateway is offline (or out of range)?

If the device has previously joined the network and reported back to the network, it will continue to send messages. However, without the gateway, the messages will not be received by the network. When the gateway is restored (or you return to gateway coverage), the network will start receiving messages again. Note:  All messages that were sent but not processed by the network when the gateway was offline or out of range will not be recovered or received.

If the device has not yet been joined to the network (or it has been “Board reset” in the LoRa Edge Config app and needs to rejoin), the device will try to rejoin about once every minute for an hour then once an hour after that.

[7] Can I mount the base station outdoors for better coverage?

You can but the case is not waterproof nor designed for high temperature extremes. You will need to place the base station within a waterproof enclosure and manage the temperature range within its specified limits.

[8] Where can I find out more about LoRa, LoRa Edge and LoRaWAN?

The LoRa Developer Portal (https://lora-developers.semtech.com/) contains a wealth of information about LoRa and LoRaWAN. Another great place to find information about LoRaWAN and its applications is https://lora-alliance.org

[9] The Tracker is not working; I am not seeing any updates or data on the map in the TagoIO dashboard?

It is critical to identify exactly what element in the system is not working. In general, please follow these steps to verify each element in the system is working.

  1. Log into your Actility account (https://community.thingpark.io/tpe/) and go to Base Stations > List and verify that your gateway is connected. 
  2. Click Devices and find your tracker in the list.  Make sure it’s connection status is “Active”.   You can also view recent packet history if you scroll down.
    1. If you do not see any recent packet activity from your device stop here and debug.   There are a number of possible root causes, including Improper credentials (DevEUI) or a problem with the Join Server. Verify your parameters.  If you still have an issue and have never seen any packet traffic from your device, consider removing it from the Actility Device list and then adding it back by following the procedure in this manual closely.
      1. From the Actility dashboard, select your device and then click the SHOW ALL button to open the advanced ThingPark Wireless Logger. From here you can see any attempted Join attempts by your device by filtering the packet type to Uplink (Join) and Downlink Unicast (Join)
      2. Verify that you see uplink Join requests from your device and successful downlink JoinAccept messages.  If you see the Uplink Join message, but no corresponding JoinAccept downlink, the device is working but there is an issue with the Join configuration of your device.  
      3. Verify your device set-up on the LoRa Cloud portal, making sure that you selected Over-the-Air Activation (OTAA) with external Join Server as the Activation mode when registering the device with Actility.
    2. Using the Android app connect to your tracker over BLE and verify you are using the latest firmware.  Also verify that your “LoRaWAN region” setting on the Tracker is correct – either EU868 or US915”.  If this setting is incorrect then you will not see any LoRaWAN packet traffic from the device on your gateway.  This will also verify the tracker device has healthy batteries. Force a reset of the device from the BLE app.
    3. Once your device successfully joins the Actility network server and you see uplink traffic for your device, proceed to opening the TagoIO dashboard, while keeping the Actility dashboard open.

      1. From the Actility Dashboard, select Applications > List and select your Tago integration.
      2. Verify that all parameters and URLs are correct.
      3. Scroll down and verify that LoRaWAN packets sent by your device are being forwarded to the TagoIO integration.

  1. From the TagoIO dashboard, select “Devices-> your device name -> Live Inspector”. You should be able to see the data sent by Actility arrive at TagoIO.  Notice the DevEUI and FCntUp values match.

If you do not receive data from your device in your TagoIO dashboard. Verify the set-up again.  Closely follow the instructions in Linking the Application Server on ThingPark Community Platform with TagoIO.

[10] Interpreting, filtering and improving the location results returned from the LR1110 tracker EVK

The LR1110 tracker has the ability to use Wi-Fi and GNSS-based location solutions.  The configuration setting of the Tracker devices’ firmware allow users to select different operational modes to optimize performance, responsiveness and battery consumption.  Please refer to additional LoRa Edge documentation for more details.  (https://www.semtech.com/products/wireless-rf/lora-transceivers/lr1110

It is expected that a GNSS location result and a Wi-Fi location result from the tracker will not be exactly the same. The default TagoIO “connector” for the LR1110 transceivermaps all the raw location data provided by the DAS geolocation server unfiltered. The TagoIO platform provides customers the ability to post-process these raw location results to improve usability.  Please refer to the detailed technical documentation of the LoRa Edge LR1110 and the tracker for more insights and optimization.
