The links allow you to download a compressed file with an old FW version (you don’t need to install it onto the tracker) and an older version of the configurator for different tracker models. | The links allow you to download a compressed file with an old FW version (you don’t need to install it onto the tracker) and an older version of the configurator for different tracker models. | ||

'''Before installing a BLE sensor and a tracker, you need to properly configure the BLE Scan sessions as indicated [[Teltonika-BLE#Bluetooth and Bluetooth 4.0 tabs (entering MAC address, BLE Scan settings)|above]]) and check the stability of the Bluetooth connection to select the best spot to install the GPS tracker/gateway (or BLE-RS485-RS232 adapter) to minimize the risks of connection losses happening in the future. Also, be sure to orient the antennas of the devices as per recommendations provided [[Teltonika-BLE#Antenna orientation|above]].''' | '''Before installing a BLE sensor and a tracker, you need to properly configure the BLE Scan sessions as indicated [[Teltonika-BLE#Bluetooth and Bluetooth 4.0 tabs (entering MAC address, BLE Scan settings)|above]]) and check the stability of the Bluetooth connection to select the best spot to install the GPS tracker/gateway (or BLE-RS485-RS232 adapter) to minimize the risks of connection losses happening in the future.

To determine if the connection between the Bluetooth transmitter of the sensor and the Bluetooth receiver is stable or not, you should use the RSSI parameter. When you search for a place to install the GPS tracker, you should calculate the average RSSI (Received Signal Strength Indicator) by taking into account the 10 or more measurements of the RSSI taken over the course of 2-3 minutes while the engine of the vehicle is running and all electronics inside the cab and around the vehicle are switched on. | To determine if the connection between the Bluetooth transmitter of the sensor and the Bluetooth receiver is stable or not, you should use the RSSI parameter.

The reason why the RSSI should be taken as the average value is that the RSSI itself is a dynamic parameter, its value changes constantly. This average value must be within the connection stability range. | The reason why the RSSI should be taken as the average value is that the RSSI itself is a dynamic parameter, its value changes constantly.
