Revision History

INTRODUCTION

Congratulations, you are now the proud owner of the Sense IoT Bluetooth Technology Evaluation Kit that will help supercharge your IoT projects.

The IoT devices in this kit are called Sense Asset. As well as harnessing the power of Bluetooth Low Energy (BLE) these intelligent devices include an accelerometer and temperature sensor to provide tracking and sensing capabilities over medium distances.

Bluetooth Low Energy (BLE) – the power-efficient version of Bluetooth is compatible with a huge range of devices and infrastructure and is available with iOS, Android or
generic protocols.

Sense Asset devices communicate with any BLE compatible Android, IOS mobile phones/tablets with off the shelf available BLE Apps as well as with physical gateways (these can be dedicated standalone devices or other smart devices with BLE listening capability) which then communicate via the network (Wi-Fi, LAN, Cellular) to a cloud or locally hosted client application server.

Due to the simplicity and price points of BLE gateways vs UHF RFID readers or LoRaWAN gateways, for example, can be installed in high volumes in areas of high device density to help ensure device data is read and processed quickly. This can be additionally helpful for location-based applications where the higher density of gateways can help to increase the accuracy of the device location given. This kit contains:

• 5 Sense Asset IoT devices
• An NFC Programmer with sync cable
• Memory Stick containing Omni-ID Sense Config PC software and electronica version of this user guide

We hope you enjoy using this kit and ‘testing your Senses’.

The Omni-ID team.

 Tag Operation

Sense Asset is designed for tracking and monitoring applications over BLE and is equipped with an accelerometer, a temperature sensor, and an LED light to indicate device status.

Sense Asset has the following built-in sensors:

• Accelerometer
• Temperature

The device has the following configurable beacon rates:

• Default Beacon Rate (DBR), configurable
•  Alarm Beacon Rate (ABR), configurable

All beacons regardless of DBR or ABR contain the following payload data:

• Local Name
• Temperature
•  Battery Voltage
• Motion Alarm
•  Temperature Alarm

DBR (Default Beacon Rate)

The default beacon rate is the frequency at which the tag beacons its sensor data under normal conditions (not in an alarm state).

The tag default beacon rate can be set as a value of 1 to 10 seconds

ABR (Alarm Beacon Rate)

The alarm beacon rate is the rate at which the device beacons when in an alarm state (motion/temperature).

The alarm beacon rate can be set as a value from 0 to 10 seconds.

Setting the value to zero disables the ABR.

The tag can switch from DBR to ABR on the following alarm events:

• Motion alarm
• Temperature alarm

Motion Alarm: A motion alarm is generated when the tag’s acceleration forces are at a value that is higher than the accelerometer threshold, this has a value between 0 and 10 where 0 is off, 10 is the most sensitive and 1 is the least sensitive.

Temperature Alarm: If the temperature of the tag goes above the preconfigured high temperature or below the preconfigured low-temperature thresholds, the tag will alarm once at the ABR, then once more when its temperature returns between them, it does not stay in ABR when it is outside of thresholds

LED Status Indicator

LED status:

• Tag in the asleep state:
  o The LED will flash fast red to indicate that the tag is in the asleep state on the press of the button
• Tag in awake state:
  o The LED will flash fast green to indicate that the tag is in an awake state on the press of the button

Supported Beacon Profiles

Sense Asset supports the following beacon profiles:

• Generic
• iBeacon
• Eddystone UUID

Generic

The generic profile also called Open of User-definable can be read by all devices and is not recognized as a brand-based profile.

The BLE asset tag version is defined in the table below:

Mobile apps will report the tag a temperature sensor:

 iBeacon

The iBeacon profile conforms to the iBeacon standard, the user is required to program the tag with 16 Bytes of UUID data and with 2 bytes of major and minor data.

The iBeacon scheme is shown below:

Mobile apps report the BLE asset tag as an iBeacon when using this profile:

Eddystone UUID

The Eddystone profile conforms to the Eddystone UID standard; the user is required to program the tag with 10 Bytes of UID data and a 6 Byte Instance.

The Eddystone scheme is shown below:

Mobile apps report the BLE asset tag as an Eddystone UID when using this profile:

Data Packet Details

The following data is always transmitted as part of the beacon:

• Local Name
• Temperature
• Battery Voltage
•  Motion Alarm
• Temperature Alarm

For all beacon types, the temperature is allocated in the byte position dictated by the corresponding beacon profile protocol, i.e., its position X for iBeacon, position Y for
Eddystone etc.

The battery voltage for all beacon profile protocols is in the same place, it can be found in the manufacturer variable data field.

This manufacturer variable field is used to store battery voltage as well as temperature alarm and motion alarm bits.

BLE beacon payload breakdown is shown as below:

Receiving / Reading Data from a Tag

Sense Asset devices communicate with any BLE compatible Android, IOS mobile phones/tablets with off-the-shelf available BLE Apps.

BLE Apps are freely available to download on compatible devices from the Play store (Android Platform) and App store (IOS Platform).

An example of the apps shown below:

• NRF Connect
• BLE Scanner

Example from NRF Connect (IOS App): Tag in Example: SenseBLE14

Data(<0xFFF> mentioned in App: 0x9E-00-C0-00
To read battery voltage we take the value 0x9E (Hexadecimal value)
Convert in Binary 10011110
Take last 5 bits 11110
Convert to Decimal = 30
Divide by 10 = 3.0
Battery Voltage = 3.0 volts

 Device Configurable settings

The device settings can be configured via NFC. Omni-ID provides both a PC software that works with ST Microelectronics M24LR Discovery NFC PCB tool or alternatively an Android application. For further information refer to Omni-ID ‘Sense Config PC App User Guide’ and ‘Sense Config Android App User Guide’.

The Sense Asset supports three types of beacon profiles, these are Generic, iBeacon, and Eddystone UUID. These values are selectable via the PC software or Android app.

The settings are the same for all three profiles.

Note: Regardless of sleep or awake status the tags will require the button pressed for two seconds for NFC settings to be read.

The following are the configurable parameters:

• Tag Type (Beacon profile): The device supports the following three beacon profiles:
  o Generic
  o iBeacon
  o Eddystone UUID
• Local Name: Device’s Unique Name/ID 0-10 ASCII Characters
• DBR: Default Beacon Rate
  o Values can be set between 1-10 seconds
• ABR: Alarm Beacon Rate
  o Values can be set between 0-10 seconds
  o Setting value to 0 will stop ABR
• Motion Threshold: Motion sensitivity of Device
  o Values can be set between 0-10
  o 1 is least and 10 is most sensitive
  o Setting value to 0 will stop the accelerometer
• This will stop the temperature sensor and report temperature as 0°C
• Hi Temperature Threshold:
  o Values can be set between -20°C to +80°C
• Low Temperature Threshold:
  o Values can be set between -20°C to +80°C
• Tag TX Power: Device’s transmit power
  o Values can be set between -15dBm to +8dBm
  o Higher the value more the read range and higher battery consumption

 Care and Maintenance
