Introduction to Backup Tracker functionality
FMB+FMB Backup Tracker is a new feature which allows to transform device's work-mode to work as a backup tracker.
Each backup tracker's scan cycle lasts up to 60 seconds. If during those 60 seconds the Backup tracker is:
- 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).
Limitations
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.

| Parameter ID | Name | Data Type | Value range | Description | ||
|---|---|---|---|---|---|---|
| Min | Max | Default | ||||
| 70200 | FMB Tracker mode | Uint8 | 0 | 2 | 0 | 0 - Disabled; 1 - Main; 2 - Backup. |

| 70202 | Update frequency | Uint16 | 60 | 65535 | 120 | Frequency, at which backup tracker should start scanning for Main Tracker BLE packets. |
| 70203 | Delay timeout | Uint16 | 0 | 65535 | 0 | Delay, after which backup tracker starts sending records after an alarm occurs |
