Timer Mode
The device counts the number of clicks detected and sends the
count in an uplink message at pre-configured intervals
Event Mode
The device immediately sends an uplink message when a click is
pressed
Heartbeat Mode
The heartbeat mode can be selected along with Event or Occupancy
modes. A heartbeat message is sent periodically by the device to

Occupancy Mode
The device sends an uplink message as it identifies the state has
changed between Open or Closed States
Open State
The state when the external connector is in the open state, for
example: the reed switch has the magnet away from it = open
Closed State
The state when the external connector is in the closed state, for
example: the reed switch has the magnet next to it = closed
Debounce Timer
A countdown timer used in occupancy mode which would be reset
every time the external connector detects a state change to
distinguish if a state is in open or closed states
Occupancy Duration
The period of time from which the debounce timer starts to
countdown so if no state change is detected past the occupancy
duration (and the timer countdown reaches 00:00) then the device
identifies the space as open

2.2. Message Type
2.2.1. Downlink Messages
A downlink message is sent from the UnaConnect platform to UnaBell LTE-M; the device
initiates the downlink process by sending an uplink message with current device information
to the cloud platform for downlink request, when the cloud platform receives the downlink
request, it will send a downlink message to update the latest configuration set in
UnaConnect to the device.
All the configurations for UnaBell LTE-M can be defined on the UnaConnect platform. The
Downlink Interval (DI) defines how often the device performs a downlink process with the
cloud platform to update the configurations. An immediate downlink message can also be
manually triggered by the user by applying an extra long click to the button (1 click and
press for longer than 6 secs).
Parameter

24 hours and is only utilized in Timer and
Heartbeat modes.
The ranges are:
●1 timer message in one day (periodic
24 hours)
●2 timer messages in one day (periodic
12 hours)
●3 timer messages in one day (periodic

Description
Occupancy
Duration
0 second
In Occupancy Modes, this sets the period of
time from which the debounce timer starts
to countdown so if no state change is
detected past the occupancy duration (and
the timer countdown reaches 00:00) then
the device identifies the state that has
changed. For example, if this is set at 10
secs, then the device will only change state
after it detects the same state for longer
than 10 secs.

2.3. Operation Modes
2.3.1. Event Mode and Messages
In event mode, the device sends an uplink message immediately each time a click type is
applied on the button.
For example, this mode can be used as a maintenance call to repair equipment on a
production line, an emergency button to call for assistance in an elderly home or a service
call for cleaning in a bathroom.
The uplink message for Event mode contains the following data:
●Message type: Event
●Sequence number: counter from 0 to 4095
●Enabled detection type: Rising edge, Falling edge, Single, Double, Long, Extra Long
Note: If the Temperature Sensor is connected as the external connector, then the current
temperature will be sent in event messages when the button is pressed
2.3.2. Timer Mode and Messages
In timer mode, the device logs a count of the number of clicks for each click type over a
period of time and sends an uplink message at an uplink frequency configured on the
UnaConnect platform.
For example, this mode can be used to count the number of maintenance or service calls
sent from the buttons installed at various points of a facility during a period of time to help
with resource allocations and operations.
The uplink message for Timer mode contains the following data:
●Message type: Timer
●Sequence number: counter from 0 to 4095
●Uplink frequency: from 1 to 144 messages per 24 hours
●Summary of number of clicks detected: Edge, Single, Double, Long, Extra Long
Note: If the Temperature Sensor is connected as the external connector, then the
temperature values will be sent in timer messages
UnaBell LTE-M User Manual 17

2.3.3. Event + Timer Mode and Messages
The event + timer mode combines the two modes so that it sends an uplink message
immediately each time a click type is applied on the button, and logs a count of the number
of clicks for each click type over a period of time and sends an uplink message at an uplink
frequency configured on the UnaConnect platform.
The uplink message for Event + Timer mode contains the following data:
●Message type: Event + Timer
●Sequence number: counter from 0 to 4095
●Uplink frequency: from 1 to 144 messages per 24 hours
●Summary of number of clicks detected: Edge, Single, Double, Long, Extra Long
2.3.4. Event + Heartbeat Mode and Messages
In event + heartbeat mode, the device sends an uplink message immediately each time any
of the click type is applied on the button, and sends a heartbeat message at an interval
configured on the UnaConnect platform.
The heartbeat message contains battery voltage data to help monitor the batteries and
manage the device lifecycle in your operations.
The uplink message for Event + Heartbeat mode contains the following data:
●Message type: Event + Heartbeat
●Sequence number: counter from 0 to 4095
●Battery voltage: remaining voltage measured in mV
●Enabled detection type: Rising edge, Falling edge, Single, Double, Long, Extra Long
UnaBell LTE-M User Manual 18

2.3.5. Occupancy Mode and Messages
The occupancy mode sends an uplink message at the start and end of a state. In
Occupancy Modes, a debounce timer counts down from a preconfigured occupancy
duration and if no state change is detected past the occupancy duration, then the device
identifies the state that has changed.
For example, if the occupancy duration is set at 10 secs, then the device will only change
state after it detects the same state for longer than 10 secs. This mode can be used with
the 2 wire accessory to connect to pressure sensors to detect the state of a seat
(occupied/vacant).
The uplink message for Occupancy mode contains the following data:
●Message type: Occupancy
●Sequence number: counter from 0 to 4095
●Sensor status: status of external I/O connector configured as Pulse or Edge mode
2.3.6. Occupancy + Heartbeat Mode and Messages
The Occupancy + Heartbeat mode sends an uplink message at the start and end of a state,
and sends a heartbeat message at an interval configured on the UnaConnect platform.
The uplink message for Occupancy + Heartbeat mode contains the following data:
●Message type: Occupancy + Heartbeat
●Sequence number: counter from 0 to 4095
●Battery voltage: remaining voltage measured in mV
●Sensor status: status of external I/O connector configured as Pulse or Edge mode
UnaBell LTE-M User Manual 19

2.4. External I/O
To fulfill an even wider range of applications and use cases, UnaBell LTE-M may also act as a
battery-powered gateway when used with its corresponding plug-and-play accessories in
addition to the embedded button on the device. The configuration in UC should be updated
to the accessory that is plugged into the device.
The accessories can be plugged to UnaBell LTE-M via 3.5mm audio jack connectors and their
main use cases are:
●Reed Switch Accessory: detect opening/closing of doors
●Temperature Probe Accessory: measure ambient temperature of the surrounding space
●2 Wire Accessory: connect with other sensors (e.g. pressure sensor)
*You can put the rubber plug inside the device casing.
2.4.1. Reed Switch Accessory
When the reed switch accessory is connected to UnaBell LTE-M, the same operation mode
and configurations for the embedded button is applied to the reed switch external I/O
connector, and the recommended detection mode for the external I/O is edge detection.
An example scenario is that the reed switch sensor is connected to UnaBell LTE-M to detect
the opening and closing of a door. The edge detection in event mode detects the instance
that the magnets are closed or separated and sends a message immediately when the door
is opened and closed.
