NOTE: Consecutive presses are ignored, if started before the SYS LED indication of

the previous press/sequence ended.

3.2.4 Battery Status Manual Check

A maintenance operator can manually check the battery status.

When the unit is active, the maintenance operator can perform a panic/distress event

by pressing the front button for a period of between 0 and 5 seconds (short press).

The SYS LED then reflects the battery SOH (State of Health):

If the SOH is above the preprogrammed minimum - the SYS LED lights for 2

seconds in

Green.

If the SOH is below (or equal to) the preprogrammed minimum - the SYS LED

lights for 2 seconds in

Red.

3.3 BLE Functionality

The method of communication between the CelloTrack and MultiSense devices is BLE

(Bluetooth Low Energy) 2.4 GHz short range low energy wireless communication. This

method of communication is intended to provide considerably reduced power

consumption, footprint and cost, with these three parameters the most important

values within the IoT world.

NOTE: BT SIG certification is currently in the product evolution process.

------------------------------------------------------------------------------------------------

Using BLE, the CelloTrack can communicate with up to 16 MultiSense devices in a

Master and Slave type setup. However, in order to function correctly as a WSN, the

CelloTrack unit and MultiSense devices must be paired, as described on page 15.

Using CelloTrack and paired MultiSense devices as a local WSN enables you to

leverage an environment, within which you can sense where different measurements

are expected such as inside cooled cargo boxes, or in a long trailer where the

environmental conditions inside the trailer may be different from those closer to the

door.

Another form of communication between the CelloTrack and MultiSense devices is via

transparent (guest) mode. In this mode, no pairing process is required and thus the

CelloTrack unit does not manage or save MultiSense device data or thresholds. As a

result, in transparent mode the CelloTrack unit can be used as a gateway to unlimited

MultiSense devices.

In situations where only MultiSense MAC addresses are required, Tag mode (similar to

iBeacon mode) can be activated.

Programming Manual.
