Industry 4.0 and IoT rely
upon devices networking
together. Although the
Internet Protocol (IP)
and WLAN connectivity
are at the forefront of the
Internet of Things, there
are scenarios in which
other techniques have
advantages. Bluetooth
Low Energy for example.
With its AMB2621 Bluetooth-LE-4.2
module, AMBER wireless, a Würth
Elektronik eiSos Group company,
opens up new possibilities in the
Smart Factory and Smart Home.
The main thrust is the use of
smartphones or tablet PCs as the
user interface for other devices.
Bluetooth Low Energy (BLE) offers
the perfect basis, as this wireless
is far more likely to be introduced
as an upgrade to existing products
and solutions. AMBER wireless
therefore paid special attention to
easy integration. From its inherent
design, AMB2621 has a firmware
stack which can be controlled via
a serial interface with commands
similar to the AT command set.
The commands available allow
developers to configure the BLE
interface for their purposes to allow
adjustment of the power and speed
of data transmission, as well as the
resulting electricity consumption of
the respective application. Other
commands control connection set-
up, data transmission and switching
to various power saving modes.
Easy to Integrate
BLE module from AMBER wireless for smart IoT solutions
Matthias Hauser, AMBER
interface is integrated in modern
smart devices as standard and can
transmit “small quantities of data”
very energy-efficiently. This makes
BLE interesting, not only for mains
powered industrial machine, but
also for battery-powered devices,
such as mobile temperature sensors
or household devices like smoke
detectors, which can be equipped
with such an interface. Furthermore,
for devices with displays there is
the potential to save the display
and if required to visualize data on
a smartphone or tablet connected
over BLE.

The Smart Factory or the Smart
Home rarely originate as green
field developments. Intelligent
networking of devices and sensors
