Introduction / Overview
The B24 Bluetooth Telemetry range provides access to quality measurements on a mobile platform such as a
phone or tablet. The delivery mechanism is ‘Bluetooth Low Energy’ (Also known as ‘Bluetooth Smart’ or BLE)
which utilises the flexibility and availability of Bluetooth receivers while maintaining the low power requirements
of embedded systems. B24 is built upon two complimentary principles of BLE, broadcast advertising data which
enables users to deliver the same data to multiple receivers simultaneously and low power connections which can
be used in a point to point system. B24 is available in OEM bare board formats and with environmentally sealed
enclosure with integrated battery holder.
This manual provides details of using B24 modules with the free Android and iOS apps for mobiles phones and
tablets.
Advertising Operation
The advertising mode of operation enables B24 modules to broadcast measurement data to multiple locations
without retransmission. The advert is an operational mode within ‘Bluetooth Low Energy’ and facilitates the
delivery of data without a connection. This mode of operation is useful in ‘many to many’ and ‘one to many’ use
cases.
This mode is used by the free apps to display live data on their dashboards where one or many B24 modules can
supply live data to one or more Android or iOS tablets and phones.

Connected Operation
The connected operational mode enables Bluetooth Low Energy devices to connect directly to the B24 module. A
single mobile device can be connected to multiple B24 transmitter modules simultaneously. This mode has a dual
purpose as it may be used monitor data and configure the device. When it is used for the delivery of data the
application can register to receive notification updates when the status and engineering unit value changes. This
mode of operation is useful in ‘one to one’ and ‘many to one’ use cases.
This mode is used in the free apps to connect to an individual module for configuration.

B24 Telemetry Basic Principles
There are some basic radio settings and concepts that should be understood to effectively configure, deploy,
optimise and troubleshoot B24 telemetry systems.
Transmission Range
The flexibility of the B24 range is that the user may utilise their mobile phone rather than using a specific
handheld receiver or base station. This flexibility does mean that Applied Measurements has no control over
the quality of the receiver. This imparts a large variation in the transmission range capability of the module.
Sensitivity Range
The input sensitivity range is designed for bridge based sensors and is configurable between ±6 mV/V and ±48
mV/V. This flexibility allows us to provide solutions for a wider range of strain gauge types.
Data rate
The Bluetooth specification specifies the maximum rate at which advertisement information can be delivered. The
B24 module may be configured to deliver data in the range between 10 samples per second and 1 every 10
seconds.
Resolution
The noise free resolution of the B24-SSB is up to 16.5 bits. This is equivalent to 1 in 92000 counts.
Transmitter Module Modes of Operation
The B24 module disconnects the power from the load cell and sleeps the micro-controller in between
measurements. This improves the battery lifetime of the system a makes the most efficient use of the battery’s
energy. There are no automatic sleep or wake functions, the modules have been designed to be ‘set and forget’
so transmit all of the time.
Data Tag
The advertising packets transmitted by B24 modules are identified by their Data Tag. The Data Tag is a four
character hexadecimal identifier that will be either printed on the modules silver enclosure label, or in the case of
an OEM module, it is the last 4 characters of the modules hexadecimal serial number (Yellow).
The Data Tag can be changed by configuring the module.
Because multiple receivers, such as apps or custom software, may be configured to use data identified by certain
Data Tags, the ability to change them in a module means that it is very simple to replace a module without
reconfiguring multiple receivers.

B24 Toolkit App
The B24 Toolkit App is available for iOS (V10.0 and above) and Android (V5.0 and above) devices and is available
for free from the App Store and Google Play store.
Use the QR codes below to access the app in the store or tap the store banner if you are
viewing this document on your device.
Google Play Store
Apple App Store
This app requires access to the Bluetooth Services which are part of Location Services so
the user may need to grant permission for the app to access Location even though the app
does not use any location data.
The App allows the user to create multiple Projects. Each project can contain a list of defined Transmitter Sources
which are B24 modules.
Each project has a Dashboard which can be populated with display Tiles that use data from the Transmitter
Sources to represent values in different formats.
When in run mode the App uses the data from the B24 module to populate the dashboard Tiles in real time.
The App will also support one to one connections with the B24 modules to enable configuration and calibration.

Splash Screen
On launching the app the splash screen will be displayed.
This displays the app version number at the bottom of the screen.

Project List
Android
iOS
The first page that appears after the Splash Screen is the Project List. This contains a scrollable list of all existing
projects. The number of projects you can add will be limited only by the memory of the phone or tablet.
Next to the user selectable icon the project title is shown and below is shown the date of the last change to the
project and the number of transmitters in that project.
After initial app installation the list will contain a single project called Demonstration.
Once you create your own project and delete the demonstration project (so only one project exists), on next
launching the app the project list will be skipped and the project dashboard will be displayed.
Controls and Actions:
x / Menu
Main Menu –See Main Menu section. From this menu you can
import a project and configure transmitters.
