* Able to catch 15 valid Main tracker packets, the scan will stop and the device will wait for next cycle to start.

* Unable to catch at least 15 valid Main tracker packets, an alarm record will be generated with AVL ID 1153. After '''delay timeout (s)''' is reached, device will send that generated record to the server and enable other record generation/sending (Periodic and Eventual record).

* All record generation is disabled. This means that if the device is not detecting the main tracker and starts generating records, it can be reconfigured or hard reset, and it will only start generating records again after the next failed scan (aka after next alarm record).

* Record sending is queued up to stop. Device waits for any currently queued up record sending to finish, so there might be a delay for this full record sending stop to occur.

===Limitations===
Since the feature relies on Bluetooth functionality, all of the existing Bluetooth limitations are applied.
Since the feature relies on Bluetooth functionality, all of the existing Bluetooth limitations are applied.
One of such limitations is the fact that FMB devices only store up to 100 BLE devices per scan. This means, that if there are more than 100 BLE devices in the surrounding environment, backup tracker being able to catch main tracker packets in time gets reduced.

==Setup instructions==
'''To ENABLE backup feature on TAT100 device:'''<br><br>
'''Both devices:'''
* Make sure <code>Ultra Sleep</code> mode → <code>Disabled</code>
[[File:Backup Tracker Ultra Sleep.gif]]
* <code>Bluetooth</code> → <code>BT Radio</code> set to <code>Enable(visible)</code>

'''Main device:'''
* <code>Bluetooth 4.0</code> → select <code>Main Tracker</code><br>

<br>
'''Backup device:'''
* <code>Bluetooth 4.0</code> → select <code>Backup Tracker</code><br>
* Enter main device IMEI (15 digits)<br>
* Set <b>Update frequency</b> to how frequent you want backup tracker to scan.
* Set <b>Delay timeout</b> to delay sending alarm record. Leave it default (0) if you want to immediately receive alarm record.<br>
