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.
