Beacon IT001 User manual

Beacon IT001 (TWHBC01 module) User Manual
IT001 is a broadcast protocol based on the bluetooth BLE protocol. It is usually installed in a
suitable location, and it will broadcast continuously or periodically to its surrounding environment
The IT001 beacon allows to create Bluetooth® Low Energy (Bluetooth LE) 5.0 solutions. Besides
basic Bluetooth LE advertising functionality via radio transmission, the TWHBC01 beacon allows
additional functionality thanks to the add-on hardware components: a green and a red LED, a push
button and an accelerometer with built-in thermometer. Depending on the casing not all hardware
components may be present or can be used. The accelerometer can be configured for detection
of specific events. Currently the following events are supported: free fall, single tap, double tap,
activity/movement and flip-flop.
There are two aspects concerning the TWHBC01 beacon firmware.
On the one hand there is a firmware implemented as a release HEX file with functionality as
described in this document. A major objective in the implementation is low current consumption
hence long battery lifetime. There are many parameters that affect the behavior of the firmware.
The release firmware has default values for these parameters.
Firmware Functionality
TWHBC01 beacon can be in five modes:
• Transport & Warehousing
• Configuration
• Operational Active
• Operational Active_Alarm
• Operational Passive_Alarm
By Operational mode we refer to the actual mode that is configured and can be either Operational
Active, Operational Active_Alarm or Operational Passive_Alarm.
Transport & Warehousing mode
As its name suggests, this mode is meant for the beacon to be silent for a long period and only to
be woken up when needed. Therefore this mode has no advertising broadcast.
Wake-up can occur on possible events:
• Accelerometer event
• Short press on push button
On wakeup the beacon goes to the configured Operational mode.
Operational Active mode
In this mode the beacon does an undirected advertising (broadcast) with frame content defined
by the configuration parameters. The broadcast can be either connectable or non-connectable.
When it is connectable, the beacon reverts to Configuration mode on connection by a (central)
client, where a new configuration can be uploaded. The connectable option should only be used
for testing purposes.
Based on configuration settings, the push button and/or accelerometer can be enabled.
On occurrence of the alarm state, which is triggered by either a long press of the push button or
on accelerometer event, the beacon stops advertising for a given period (alarm duration timer),
after which it restarts normal broadcast.
Operational Active_Alarm mode
This mode is similar to the Operational Active mode, except that during the alarm state the beacon
broadcasts an alarm frame instead of being silent.
On occurrence of the alarm state, the beacon starts an undirected alarm broadcast for a given
period (alarm duration timer), after which it restarts normal broadcast.

Operational Passive_Alarm mode
This mode is similar to the Operational Active_Alarm mode, except that the beacon is silent until
an event occurs.
Configuration mode
This mode is used for testing and configuration. In this mode the beacon does undirected
connectable advertising. This mode is entered when the Operational mode is connectable and a
(central) client connects. When connected the (central) client can interact with the Configuration
Service in the beacon. The only way to leave the Configuration mode is by uploading and activating
a valid TLV file.
Alarm broadcast
The broadcast in the alarm state of modes Operational Active_Alarm and Operational
Passive_Alarm consists of just one frame type and can be either connectable or non-connectable1.
Behavior on reset
On reset the beacon checks whether valid TLV configuration file is present in flash. If so its
configuration values are used. If no TLV file is present or is erroneous, the beacon uses the default
configuration.
To show which of these is the case the beacon flicks LEDs just after startup:
• Twice green LED when TLV content is used.
• Green LED followed by red LED when TLV configuration is not supported.
• Twice red LED when TLV configuration is supported but TLV data are erroneous.
Product specification
Product usage scenario:

Asset tracking and location in an industrial environment.
People flow management, secure access control, People monitoring in certain areas.
Product installation method
The beacon can be stuck onto objects with a strong adhesive surface on it's backside. For
removable versions, the Beacon can be supplied with an extra strong Velcro surface
