1.3.1 Bluetooth Low-Energy (BLE) Receiver
The Enterprise Asset Tracker (ATEX) is equipped with a BLE module that is embedded in the MCU.
It serves as a BLE central device that periodically searches to discover nearby BLE peripherals. It can be used as a standalone proximity Tracker that can also help at positioning.
The BLE scan can be disabled entirely or enabled at any time. Figure 1-3 shows the BLE scan scheme when the BLE scan is enabled. As shown in the figure, BLE scans are performed periodically. Each scan duration is divided into scan intervals. The BLE scan is performed only in the scan window portion of the scan interval. The ratio of the scan window to the scan interval is the scan duty cycle. In the case of the scan window equalling the scan interval, the scan duty cycle is 100%. This represents a continuous scan over each scan duration. A larger duty cycle will increase the likelihood of receiving more beacon packets at the expense of consuming more power. The scan period, duration, interval, and window are all configurable. For all user configurable device settings, refer to the TRM document for the Tracker.   Figure 1-3: The BLE Scan Schematic Procedure.
All BLE peripheral devices are discoverable during BLE scans. At the end of each scan duration, up to n discovered BLE devices with the strongest RSSIs are reported over LoRaWAN. The value n is user configurable. If no devices are found, an empty list is uplinked. Over each scan duration, a BLE device beacon may be observed (discovered) more than once. The Trackers do not support BLE Tx advertising.
The Enterprise Asset Tracker (ATEX) support BLE of Bluetooth 5.0. The BLE scan is performed in the passive mode only, meaning that the Tracker listens to surrounding beacons, but does not transmit to them to request additional information.
NOTE: The BLE scan is exclusive to LoRa radio transmission; i.e. they do not overlap. If any reporting becomes due at the same time of a BLE scan, the reporting will be done after the BLE scan is complete.
1.3.2 Magnetic Reed Switch
The Enterprise Asset Tracker (ATEX) is equipped with an internal magnet actuated reed switch.
Since the Tracker has a water-tight IP67 enclosure, there is no ability to have battery pull-tabs or reset button pinholes. The reed switch therefore address the following purposes:

1. To wake the device from sleep (the Trackers are shipped in a state of deep sleep).
2. To put the device to sleep.
3. To reset the device (since the Trackers do not have a reset button).
4. To force an UL.

A magnet for this purpose is available upon request. The position on the exterior of the enclosure on which the magnet must be placed to activate the reed switch is shown in Figure 1-2.
For more information on how to wake the device from sleep, refer to Section 2.4. For more information on how to use the reed switch for the other purposes, refer to the specific TRM document for the Tracker.
1.3.3 Accelerometer Transducer
The Enterprise Asset Tracker (ATEX) supports motion sensing through an integrated 3-axis accelerometer which can optionally be disabled. The main role of the accelerometer in the is to detect motion that can indicate a change of the Tracker’s status from stillness to mobility, or vice versa.
The accelerometer can also be polled periodically for its output acceleration vector for applications in which the Tracker’s orientation is of interest.

2.3 Unpacking and Inspection
The following should be considered during the unpacking of a new Tracker.

1. Inspect the shipping carton and report any significant damage to TEKTELIC.
2. Unpacking should be conducted in a clean and dry location. Unpacking of the Enterprise Asset Tracker- ATEX Tracker (T0007367) must be done in a non-explosive environment.
3. Do not discard the shipping box or inserts as they will be required if a unit is returned for repair or re-configuration.

2.4 Commissioning and Activation
Each Tracker has a set of commissioning information that must be entered into the network server in order for the Tracker to be able to join the network and begin normal operation once activated. For instructions on how to do this please refer to the Network Server Quick Start Guide (available online in the Knowledge Base).
The Tracker is shipped in a secured enclosure with the battery preinstalled. The device is shipped in a state of deep sleep. A magnet can be used to wake the Tracker from sleep by applying the magnetic activation pattern at the location specified on the device in Figure 1-2. The magnetic pattern is illustrated in Figure 2-1. A “magnet presence” is achieved by attaching the magnet to the enclosure at the magnet symbol. A “magnet absence” is achieved by taking the magnet away from the enclosure. Figure 2-1 shows that the pattern involves sustaining a “magnet presence” continuously for at least 3 s but less than 10 s. Figure 2-1: The C-Cell Tracker Variant Magnetic Activation Pattern
Once activated, the Tracker will automatically begin the join process. To turn the Tracker off, the battery must be removed. To reset the device without taking the battery out, see Section 3.4 for a description of the reset function.
