Restricted distribution
Button down when device is ON
Blue LED ON
4.5.2 LED interface
One of the two interfaces between the user and the tracker is done via the LED interface. Several patterns
have been defined for different outputs.
LED blinking patterns
Three fast blinks
Go to the OFF mode (Low battery or user operation)
Three slow blinks
Device starting for the first time
Long fast blink of blue LED
LoRa join operation in progress
Fast blink of blue LED after two button clicks
Device acknowledges the alert position
Slow blink of blue LED after two button clicks
SOS mode. Blinking remains until the mode is left
4.5.3 Buzzer melodies
The second interface between a user and the tracker is done via a buzzer.
Up to nine different melodies have been defined:
Melody
Meaning
Device reset
Device is resetting/ going to bootloader
Major rising scale
Device is starting
Major falling scale
Device is going to OFF mode
Low battery
Low battery detected
SOS stop
SOS mode is left
BLE bond on going
Tracker in not bound. Waiting for a bond
BLE bond failure
Bond process unsuccessful
BLE bond success
Bond process successful
BLE alert
Alert activated from connected device using BLE
Note:
1- A zip file containing the different sounds can be found in the same folder than this document.
4.6 Geolocation strategies
4.6.1 Main operating modes
The following geolocation policies (geoloc_sensor parameter) are used by the operating modes: motion-
tracking, permanent-tracking and start/end tracking. Note that in standby mode, only side operations can
report positions.
➢ WIFI only → Only WIFI scans are used for position determination.
➢ GPS only →Only the GPS is used for position determination.
➢ LP-GPS only→ GPS and low power-GPS are used for position determination.
➢ Multimode (WIFI + AGPS + GPS) → Alternate WIFI, LP-GPS and GPS technologies on failure, with
timeout. Superseded by WIFI-LPGPS/ WIFI-GPS mode.
➢ WIFI-GPS only → WIFI then GPS if WIFI fails in one geolocation cycle.
➢ WIFI-LPGPS only → WIFI then Low power-GPS if WIFI fails in one geolocation cycle.
➢ WIFI-LPGPS/ WIFI-GPS → WIFI-low power GPS first, then WIFI-GPS if WIFI-low power GPS fails until
timeout, then back to WIFI-low power GPS.
➢ BLE beacon scan only → Provide data formatted as a list of “MAC address/RSSI” couple that can be
used to compute a position
