➢ Personal tracking with help button.
➢ Safety monitoring for isolated workers inside facilities or in outdoor.
➢ Anti-theft; Notification and location when device is moving.
➢ Geofencing applications.
2 Features
➢ Multiple operating modes
• Motion tracking: Get the tracker position at a given cycle when motion is detected.
• Permanent tracking: Get permanently a position of the tracker.
• Start/End motion tracking: Get position messages during motion start and end
events.
• Activity tracking: Monitor activity rate with embedded sensors.
• OFF: device stopped
➢ Position on demand: Receive the tracker position only when needed (very low power
operating mode).
➢ Used geolocation technologies
• GPS: Precise outdoor position.
• Low power GPS: get quick position outdoors and daylight indoor conditions.
• WI-FI: Position indoors and urban area.

3 Installation
3.1 Getting started
➢ Charge your device using a micro USB cable. While charging the white led is ON. When the
battery is fully charged the white LED goes OFF.
➢ A long press is needed to turn ON the device (starting in motion tracking mode in standard
configuration).
➢ Your network can use two activation modes:
o OTAA (Over The Air Activation) that requires the following keys to make the join: DEVEUI,
APPEUI and APPKEY for each device. (the most used)
o ABP (Activation by personalization) that requires the following keys to make the join:
DEVEUI, DEVADDR and NWKSKEY for each device
➢ Depending on your operator, some actions need to be done to activate the transfer of the
data through Abeeway servers. Please refer to your vendor for more information.
3.2 Fixation
The device can be attached with the provided lanyard or placed in bag, or inside an asset.
Note: the environment and orientation of the tracker can influence the radio performance. For
optimum results keep the zone around the antenna area clear from any conducting material or
magnetic field.

4 Functioning
4.1 Main operating modes
This section describes the different operational modes supported by the trackers.
OFF mode: The tracker is in deep low power mode. No uplinks are sent in this mode. A long button
press is required to wake it up. Three possibilities to set the tracker in OFF mode:
➢ User action (long button press)
➢ Low battery
➢ Downlink request
Standby mode: The tracker is sending periodically short LoRa messages, called heartbeat at the
chosen period (lora_period). Device position can be obtained in this mode by using the side
operations features (see next section).
Motion tracking mode: The tracker provides positions when the device is moving. The reporting is
done at the chosen period (ul_period). The positions are acquired based on the geoloc_sensor
geolocation technology. If the device is not moving, heartbeat messages are sent regularly at the
lora_period frequency. Additional positions can be obtained by using the on-demand side
operations features.
Note: Whatever the chosen geolocation policy, the first position is always established via WI-FIWiFi sent immediately after the beginning of the motion.
Permanent tracking mode: The device reports its positions at ul_period frequency regardless the
motion. It uses the geoloc_sensor geolocation technology. Heartbeat messages are sent if there are
no uplink message during lora_period seconds.
Motion Start/End tracking mode: In this mode, position messages are sent twice, at the start and
at the end of a motion (one Wi-Fi and one using the geoloc_sensor geolocation technology). The
end of the motion is detected when there is no movement detection for a period of 120 seconds.
Heartbeat messages are sent if there are no uplink message during lora_period seconds. Additional
positions can be obtained by using the on-demand side operation feature.
Activity mode: This mode sends activity reports instead of positions. The tracker focuses on
detecting movements. Each shake detection increases a counter (after applying an integration
period). The value of the counter is reported up the LoRa link at the ul_period frequency. Heartbeat
messages are sent if there are no uplink messages during lora_period seconds. Additional positions
can be obtained by using the on-demand side operations features.
Note: The accuracy of the different frequencies is not guaranteed as extra delay may be introduced
by the LoRa network duty cycle.

4.2 Side operations
Whatever the mode, optional messages can be sent according to the configuration. The side
operations can be:
Periodic position message: The device sends periodically its position at periodic_pos_period
frequency. Usually, this reporting frequency is very long. The position is sent three times (six if the
device is moving).
Position on Demand: Position requests are done via LORA downlink message. The device answers
with its current position.
Alert position: A double press on the button generates a LORA uplink message containing the
position.
Notes:
➢ The geolocation strategy used in these cases is geoloc_method one.
➢ The side operations can be cumulated.

4.4 Geolocation strategies
4.4.1 Main operating modes
The following geolocation policies (geoloc_sensor parameter) are used when the operating mode
is either motion-tracking, permanent-tracking, or start/end tracking.
➢ WI-FI only → Only WI-FI scans are used for position determination.
➢ GPS only →Only the GPS is used for position determination.
➢ LP-GPS only→ GPS and LP-GPS are used for position determination.
➢ Multimode (WI-FI + AGPS + GPS)→ Alternate WI-FI, LP-GPS and GPS technologies on failure,
with timeout.
➢ Wi-Fi-GPS only → WI-FI then GPS if Wi-Fi fails in one geolocation cycle.
➢ Wi-Fi-LPGPS only → Wi-Fi then LP-GPS if Wi-Fi fails in one geolocation cycle.
➢ Wi-Fi-LPGPS/ Wi-Fi-GPS → Wi-Fi-LPGPS first, then Wi-Fi-GPS if Wi-Fi-LPGPS fails until
timeout, then back to Wi-Fi-LGPS.
Note: The first position is always a Wi-Fi one whatever the chosen geolocation strategy.
4.4.2 Side operations
The following geolocation policies (geoloc_method parameter) are used for periodic-reporting or
on-demand actions.
➢ Wi-Fi only → Only Wi-Fi scans are used for position determination.
➢ GPS only →Only the GPS is used for position determination.
➢ LP-GPS only→ GPS and LP-GPS are used for position determination.
➢ Wi-Fi-GPS only → Wi-Fi then GPS if Wi-Fi fails in one geolocation cycle.
➢ Wi-Fi-LPGPS only → Wi-Fi then LP-GPS if Wi-Fi fails in one geolocation cycle.

7 Downlink messages
These messages are sent from the server to the tracker through the LoRa network. They are used
to configure the tracker or request a position. Each message contains a header including:
➢ A message type
➢ An acknowledgement token
The remaining of the message depends on the message type. The tracker accepts three types of
downlink messages, listed in the following table:
Message type
ID
Description
POD
0x01
Position on demand
Set Mode
0x02
Change the tracker mode
Set Param
0x0B
Modify a parameter
Notes
1. Any unexpected message (unknown message type, bad length, ...) is discarded. However,
the ack token is updated even if the message is discarded (if the payload is at least 2 bytes
long).
2. The LoRa port to be used for downlink is 2.
7.1 Ack Token
It provides a way to indicate to the application that a given message has been received and
processed by the tracker.
The ack token is transmitted in every uplink message, and it is updated when the tracker receives a
LoRa message. This way, each time the server receives a LoRa uplink, it knows whether the previous
message has been received.
The ack token is four bits long. Its value ranges from 0 to 15(0x0F).
Notes
1. The ack token value should be updated for each downlink to be used by the application.
2. It’s up to the application to process or not the ack tokens.
3. It’s up to the application to manage the confirmations. It can either wait for the matching
ack token in the uplink message before sending another downlink or send multiple downlink
and later waits for the acks.
