WIRELESS CONNECTIVITY & SENSORS
User manual Proteus-II
Bluetooth
®
5 stack:
The Bluetooth
®
5 stack enables fast and energy efficient data transmis-
sion using state-of-the-art technology of Nordic Semiconductors.
High throughput mode:
The Proteus-II contains the so called "High throughput mode" that
allows to send up to 4 data packets per connection interval. This increases significantly
the throughput. This mode and its usage is described in application note ANR006 [4].
All Bluetooth
®
LE roles supported:
The integrated Bluetooth
®
LE stack supports all
Bluetooth
®
LE roles. Depending on the current state of operation the Proteus-II firmware
automatically switches its role to execute the user’s instructions.
Flexible wired interfacing:
If custom hardware does not support UART communication or in
case of a host less implementation, the Proteus-II is equipped with extra pins suited
for custom device/sensor connection. With help of these, a tailored firmware can be
developed which is optimized to the customer’s needs. The pins can be configured to
various functions such as UART, SPI, I2C, ADC, PWM, NFC and GPIO.
OTA firmware update:
The Proteus-II firmware provides over the air firmware update capa-
bilities. Firmware updates can be applied using the Nordic Apps for cell phones.
Peripheral only mode:
The Proteus-II firmware provides the "peripheral only" operation mode
(see chapter
), that allows the easy adaption of already existing custom hardware 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 hardware 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.
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-II devices, the WE
SPP-like profile must be known and implemented by all network participants. Thus arbitrary
Bluetooth
®
LE devices (like iOS or Android devices) must implement this profile, too. To do so,
the Proteus-II application note ANR005 [3] contains the design data of the WE SPP-like profile.
