ztrack Pro LoRaWAN GPS Tracker User Guide

Transcription

1 ztrack Pro LoRaWAN GPS Tracker User Guide Introduction ztrack Pro is a revolutionally small LoRaWAN based GPS tracking device. The device is widely used to track pets, children, bicycles, elderly people, bags, assets. In case of average usage (2 hours of motion per day with 5 minutes sending period) ztrack Pro can work for up to 2 weeks with one single charge. Charging is done wirelessly by a Qi charger and it takes 1 hour to fully charge the device. The ztrack Pro tracker has GPS and WiFi module (for device configurability), an accelerometer and a temperature meter inside. Revision: v1.0 Page 1 of 10

4 3 Hardware configuration 3.1 Status LED There is a red LED indicator on the ztrack Pro to inform you about specific events during operation. The LED positioned on the left bottom section of the device: The LED illuminates only in one color, so the different events indicated with the number of blinks: Blink count Event 1 blink Uplink message has been sent 2 blinks Device wakes from idle mode (motion detected) 4 blinks Downlink message accepted Table 2. LED event description While the device is charging via Qi charger, the LED lumination is inverted (LED is constantly on while there is no event). 3.2 Battery and charging The built-in LiPo battery can power the device for around 2 weeks. Battery lifetime highly depends on the device configuration. The battery can be charged with any Qi-compliant wireless charger. The device should be placed on the charger with the ztrack logo facing upwards. Charging takes approx. 1 hour. When the battery is fully charged the LED goes off. Revision: v1.0 Page 4 of 10

5 3.3 Device identifier Every ztrack Pro is shipped with a unique 64-bit HW-EUI. This HW-EUI is engraved into the back side of the enclosure: For more information on the utilization of HW-EUI, please refer to the 4. Get started with the device section. 4 Get started with the device The ztrack Pro can be used with any LoRaWAN- network, service provider as long as it complies with the LoRaWAN network standard. The device is shipped without any LoRaWAN related configuration. To start using the device, it must be configured first. (If you need preconfigured devices, please contact our sales department at sales@zane.hu). 4.1 Configuring the device The ztrack Pro can be accessed and configured via WiFi connection. The available features are: device specific settings LoRaWAN configuration (EUIs, keys, etc.) and firmware upgrade. Necessary tools to configure a ztrack Pro: PC with WiFi and Windows OS Qi wireless charger zutility desktop software (download link and documentation provided at ) Revision: v1.0 Page 5 of 10

6 4.1.1 The process of configuring the device: 1. The ztrack Pro creates a WiFi access point only if it s being put on a wireless charger. If the device detects 2 minutes of inactivity via its WiFi module, the access point will be deactivated. In order for the access point to reappear, the device must be put on the charger again. The SSID is built up from the device s name, HW-EUI, and which mode the device is in: Application mode SSID Bootloader mode SSID ztrack_pro_xxxxxxxxxxxxxxxx ztrack_boot_ XXXXXXXXXXXXXXXX (Bootloader mode is used for firmware upgrade, refer to 4.2 Firmware upgrade section for more details) 2. Once the PC successfully connected to the ztrack Pro via WiFi, the device can be configured for device settings, LoRaWAN configuration, and firmware upgrade with the help zutility desktop software. For more help on how to use zutility, refer to ZD zutility User Guide, available on Device settings The device settings determine how the ztrack Pro behaves. These settings are highly responsible the performance and battery life of the product. Tracking Time Setting Name Range Default Value Tracking Time [s] Keepalive Time [s] GPS Fix Time [s] GPS Accuracy Time [s] GPS Status Enabled / Disabled Enabled Motion Sensor Status Enabled / Disabled Enabled Table 3. Device settings description The device activates the GPS tracking if the motion sensor detected any movements. When the coordinates have been sent to the LoRaWAN network the device goes back to sleep for a while. This setting determines the idle period between GPS messages. Shorten tracking time makes better time resolution during tracking and needs higher energy consumption. Longer tracking time makes less frequent tracking and longer battery time. Revision: v1.0 Page 6 of 10

7 Keepalive Time The time between regular keepalive messages. Keepalive messages only sent while the device is idle (no motion is detected). GPS Fix Time The maximum time while the device can search for GPS satellites. Longer time makes more satellites available, even if the sky is covered or partially covered. However, it may also increase power consumption. Shorter time preserves battery life, but the tracker may not find satellites in all cases. Recommended general setting is 240 seconds (4 minutes). GPS Accuracy Time The additional time is that we wait for GPS stabilization after the GPS fix signal acquired. Longer time results more power consumption and better position accuracy. For 10-20m accuracy, 10 second is typically enough. GPS Status Status of the GPS module. When enabled, the tracker operates as intended. You can benefit from disabling the GPS module, when you know you will be indoor for a longer period. This way the battery life can be preserved. Motion Sensor Status Status of the motion sensor. When enabled, the tracker will be active on detected motions and operate as intended. When the motion sensor is disabled, the tracker will only send keepalive messages. Example on the operation of ztrack Pro: - GPS enabled - Motion sensor enabled If the device is in soft idle, it will only become active when motion is detected. Otherwise, the device will send a keepalive message every Keepalive Time seconds. Once the device is active from a motion event, it will start to wait for a GPS fix for maximum GPS Time period, and send the results via LoRaWAN (either coordinates or no GPS fix event). If motion was detected while waiting for GPS fix, the device will go into a hard idle state for Tracking Time period. After Tracking Time period elapses, the device will attempt to acquire another GPS fix and send the results. If no motion is detected, the device will go into soft idle state again for Keepalive Time or until motion is detected. Revision: v1.0 Page 7 of 10

8 4.1.3 LoRaWAN settings Several LoRaWAN related parameters are adjustable on the device. The process of changing these are the same as with device settings. Setting Name Range Default Value DevEUI - HW-EUI AppEUI / JoinEUI - - DevAddr - - NwkSKey - - AppSKey - - AppKey - - Datarate DR0 DR5 DR0 ADR Status Enabled / Disabled Disabled Join Mode ABP / OTAA ABP Table 4. LoRaWAN settings description For more information on how to adjust LoRaWAN settings, refer to ZD zutility User Guide, available on Firmware upgrade The firmware of ztrack Pro is under continuous development. You can always find the latest firmware release and release notes on Firmware upgrade can be performed via WiFi using zutility device configuration tool.
