4.6.3.2 Low power GPS
In this mode, the device sends the data given by the GPS module before the agps_timeout delay expiry and
the position calculation is done in our server.
If the GPS module didn’t succeed in having enough data to provide to the server, a LP-GPS timeout message
is sent instead of a LP-GPS data message.
Note:
1- If a period smaller than agps_timeout is set for ul_period the LP-GPS timeout used will be ul_period
instead of agps_timeout
4.6.3.3 WIFI
Since a WIFI scan is always done within five seconds, there is no timeout parameter.
Once the scan is done, BSSID are sent via LoRa with the related RSSI and the position calculation is done in
our server.
In a multi technology geolocation strategy, a WIFI scan with less than 3 BSSID triggers a technology switch.
Regardless the number of BSSID (including 0) a WIFI position is sent.
In the case where the communication fails with the WIFI module, the device sends either a WIFI failure
message or a WIFI timeout message.
4.6.3.4 BLE
In this mode, the device scans to find up to ble_beacon_count number of BLE beacons before the
ble_beacon_timeout delay expiry.
Once the scan is done, the BLE beacon MAC addresses are sent via LoRa with the related RSSI
In the case where the BLE module fails to detect BLE beacons, the device sends a BLE failure message.
Notes:
1- BLE Beacons must be at least compliant with:
• iBeacon (Apple)
