Peripheral only mode:
The Proteus-III firmware provides the "peripheral only" operation
mode (see chapter
), that allows the easy adaption of already existing custom hard-
ware with the Bluetooth
®
LE interface. By default, this mode offers the static passkey
pairing method with bonding and a transparent UART interface. With this, custom hard-
ware can be accessed by mobile Bluetooth
®
LE devices (like smart phones including
a custom App) using an authenticated and encrypted Bluetooth
®
LE link without the
need of configuring the module.
Additional Bluetooth
®
5 radio modes:
The Proteus-III provides the advanced radio modes
2 MBit mode for faster data transmission and the LE coded mode, that allows long
range data transmissions. For more information, see chapter
Long range connect:
For backward compatibility reasons, a Bluetooth
®
LE connection is
setup using the legacy 1MBit radio mode and can then be updated to long range mode.
The Proteus-III allows in addition to setup the connection immediately using the long
range mode, such that even connections can be initiated on high distances. More
information can be found in chapter
Fast sensor data transmission via Beacons:
The Proteus-III supports the transmission
and reception of Beacons. Beacons are fast broadcast messages that allow the energy-
efficient unidirectional transmission of data. Especially in sensor networks, this feature
is suitable for the frequent transmission of measurement data as it avoids the need for
a connection-based communication and therefore is more energy efficient.
1.1.2. Connectivity
The Bluetooth
®
LE standard allows to setup a network with various Bluetooth
®
LE devices
from different manufacturers. To be able to communicate with Proteus-III devices, the AM-
BER SPP-like profile must be known and implemented by all network participants.
The advanced developer guide of Proteus-III (Application note ANR009) contains the design
data of the AMBER SPP-like profile, to implement it for example in smart phone apps.
