Connecting a sensor to a smartphone
To configure any TD-BLE sensor, to calibrate it and to do the tank calibration, you need to use
Escort Configurator app available on iOS and Android devices (hereinafter - the “app”).
Geolocation
Run the configurator. Be sure to give it access to your smartphone’s geolocation. Activate the
Bluetooth and the geolocation of your smartphone (Fig. 1). The app must have access to the
geolocation due to the requirements of the AppStore and GooglePlay (Fig. 2).

Connecting sensor
Tap on the Sensor settings button. Next, select TD-BLE.
Fig. 2 Sensor settings
Fig. 3 Connection and sensor type
Search for a particular sensor by introducing the last 6 digits of its serial number. The serial
number can be found on the sensor’s head.
Or simply find the sensor you need on the list and tap on the Connect button. When using an
Android device, you can also tap on the sensor itself to open the dropdown menu displaying the
data received in the advertising mode.

Sensor’s main parameters and readings
On the main screen of the sensor you can see the following parameters:
1) The serial number of the sensor
2) Version of the firmware (hereinafter - FW) installed on the sensor
3) The temperature measured by the sensor
4) The level reading - fuel level reading as a value from 1 to 1023 or from 1 to 4095 range; this is
not a reading in liters but more on that later
5) RSSI - Received Signal Strength Indicator that shows how well your smartphone receives the
data from the sensor; this parameter is NOT transmitted by the sensor but is calculated by the
device that receives the data from it;
6) Vbat or sensor’s battery charge (3.5V or more means that the battery is fully charged; 3.2V or
lower voltage means that the battery is discharged and has to be replaced);
7) The MAC address of the sensor is used to pair the sensor with the compatible trackers;

Battery charge drops to 3.2V or lower that last for 10-15 minutes are acceptable (especially if
it happens after the sensor is rebooted by taking its battery out and then putting it back). This
happens because all processes that are run by the sensor (level, temperature and battery charge
measurement as well as transmission of the BLE data packages) synchronize and, thus, the power
consumption of the device increases while the battery voltage decreases.
Sensor calibration
CNT. What happens when you calibrate the sensor
After you cut or extend the tubes of the sensor, you need to recalibrate it, i.e. to set its new Full
and Empty calibration values. You can do that in the Settings menu (Fig. 8, 1).
Fig. 8 Settings. Additional Features. Tank calibration

The sensor’s “raw” readings - current level or CNT - change depending on how much fuel there
is in the sensor’s tubes.
The CNT is then compared with the Empty and Full values.
If the tubes are empty and “CNT (Fig. 9, 1) ≈ Empty calibration value (Fig. 9, 2)”, the level is
displayed as 1.
