If there is a connection loss, after several attempts to collect the data (the '''Scan retries until error''' setting in the Bluetooth 4.0 tab) the tracker will transmit the error '''code 3000/300 in the temperature io'''. The level value will be transmitted as the last reading transmitted by the sensor if it was connected via the BLE base, or '''0\-4\65532''' in the fuel data. | If there is a connection loss, after several attempts to collect the data (the '''Scan retries until error''' setting in the Bluetooth 4.0 tab) the tracker will transmit the error '''code 3000/300 in the temperature io'''.

Also, be sure to orient the antennas of the devices as per recommendations provided [[Teltonika-BLE#Antenna orientation|above]].''' | ||
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.
