2 Installation
2.1 Before installation
2.1.1 Unpacking and accessory checking On very first use, verify that the device's SN, IMEI listed on the box's label matches what is printed on the back of device.

 Accessory Here is the component list:
1. ATD521 2. Package 3. USB to Type-C cable 4. 5V/2A DC Charger

2.1.2 Activate the Device The device is placed into "Set Up" mode at production. This is a low power mode where the device is dormant and requires user action to active. To determine whether the device is Active or in "Set Up" mode, pressing the device's button down momentarily for one second or less. If the LED2 blinks once, the device is activated. If the LED2 blinks twice, the device is in "Set Up" mode, and will needs to be put into an active (Long press the button for more than 3 seconds).

Figure 2.3 Button
2.1.3 Device Configuration There are two ways to config the device: UART and over the backend. Key items The APN, MQTT server URL (and Port) and cell RAT need to be configured first. Otherwise, the device cannot establish a connection. RAT selection options
 0: 2G only  1: 2G + NB (NB ­ narrowband is not supported)  2: 2G + NB + M1 (NB ­ narrowband is not supported)  3: 2G + M1  4: NB only (not supported)  5: NB + M1 (NB is not supported)  6: M1 only

3 Function
3.1 Periodic Sensor Scanning
Sensor sampling and a report is performed once every monitorPeriod and reported to the server once every commSynchPeriod. Refer to the referenced Data Model for further details. Note that the device internally treats rounds the monitorPeriod and commSynchPeriod down to the nearest minute. For example, if either are configured to 239 seconds (3 minutes, 59 seconds), the resultant configuration value will be set to 180 seconds (3 minutes).
3.1.1 Sensors 1. Temperature: -20 deg. C to +80 deg. C (operational limits of the device) 2. Humidity: 0 to 100% relative humidity 3. Accelerometer g-force, x, y, z axes: -16.0000 to +16.0000 g-force 4. Tilt Angle x, y, z: 0 to 90 degrees of tilt relative to the vertical 5. Light: 0.01 to 64k lux. 6. Pressure: 260 to 1260 hPa. 7. Temperature Probe (one wire temperature): -20 deg. C to +80 deg. C (operational limits of the device)
3.1.2 GNSS/GPS Location and WIFI Scanning GNSS/GPS is scanned with each sensor report to get the device's location. If a GNSS/GPS fix cannot be achieved, WIFI is scanned for access point data for use with WIFI LAAS.
3.1.2.1 GPS/GNSS Data Latitude, Longitude, Speed (m/s), Bearing (deg), Altitude (m), Accuracy (m)
3.1.3 Coarse Location Data Connected cell tower and neighboring cell tower data are included with every sensor report. Cell Id, MNC, MCC, LAC, TAC, Operator ID, Signal Strength, RAT, Neighbor Cell tower Data
3.1.4 Data Report Format Refer to the data model for further details.

3.2 Button Press Driven Scanning
Button presses can result in the device publishing a sensor report to the server. The format and content of the sensor report is the same as that with periodic reporting, except the indicated type of message will differ (periodic: "per", button press "btn", Active Mode Entry: "norm", Setup Mode Entry: "stp").

3.2.1 Double-Button Press Pressing the button twice quickly results in a dedicated ("btn") sensor report published to the MQTT server. Note that the device will not recognize more than one double-button press every 3 minutes.

When the double-button is pressed, the LEDs will illuminate and when the LED1 Green stops flashing and illuminates solid, the device has published the message to the server.

3.2.2 Long Button Press for Entry into Active Operation Pressing the button continuously for 3 seconds or longer results in the device transitioning to/from Setup Mode and Active Operation.

3.2.2.1

Active Mode Entry

The device publishes a dedicated ("norm") sensor report to the MQTT server when the device initially enters Active Mode (from Setup Mode via

a long button press) or when the device boots up for the first time.

3.2.2.2

Setup Mode Entry

The device publishes a dedicated ("stp") sensor report to the MQTT server before the device enters Setup Mode (from Active Mode).

3.3 Configuration

3.3.1 monitorPeriod The monitorPeriod controls the number of sensor reports made per time period. Its units are programmed in seconds, but are internally rounded down to the nearest minute internally by the device (e.g. 239 seconds is treated as 180 seconds, or 3 minutes).

Range: 180 seconds to 15,552,000 seconds. Recommended not setting to values longer than 24 hours or 86400 seconds.

3.3.2 commSynchPeriod The commSynchPeriod controls the number of times all collected sensor reports are published per time period. Its units are programmed in seconds, but are internally rounded down to the nearest minute internally by the device (e.g. 239 seconds is treated as 180 seconds, or 3 minutes).
10

Range: 180 seconds to 15,552,000 seconds. Recommended not setting to values longer than 24 hours or 86400 seconds. The commSynchPeriod should not be programmed to be less than the monitorPeriod and should not be programmed to be more than 12 x the monitorPeriod
3.3.3 opMode The opMode is used to command the device into Setup Mode. Values: 1: Keep device in Active operation. 0: Place device into Setup Mode
3.3.4 reportBuffReset The reportBuffReset is used to command the device reset its `history' buffer of sensor reports collected while the device has been offline from the network. Values: 1: Reset the history buffer.
3.3.5 alarms Please refer to the data model to config below alarms:
lowBatt: low battery alarm tempAlarm: temperature overflow/underflow alarm humiAlarm: humidity overflow/underflow alarm liteAlarm: lite overflow/underflow alarm owtAlarm: one wire temperature overflow/underflow alarm shockAlarm: shock alarm tiltAlarm: tilt alarm reportType: motion-based periodic reporting enable/disable owtDisc: plug out one wire sensor Motion: motion monmotion config

3.3.6 motion & nomotion Reporting type is like this: "tripStrt": Trigger motion status during nomotion period "Movg": Trigger motion status during motion period "TripStp": Trigger nomotion status during motion period "stnry": Trigger nomotion status during nomtion period

3.4 LED Indicators

3.4.3 FOTA (F/W Over-The-Air Update) While FOTA is active, the device is actively receiving a F/W image. During this time, all LEDs will blink at approximately a 5Hz rate. As the FOTA is about to complete, the LEDs may illuminate steady for approximately one minute. This is normal.

4 Historical Data
4.1 Historical Data
The device retains up to 600 `historical' sensor reports if the device cannot establish a network connection. Once the 600 reports limit is reached, the list will be reset. Once the device can attach to the network and MQTT server, it will publish all historical data.
