User manual Proteus-III

1.1.1. Key features

The Proteus-III offers the following key features that are described in the manual in more detail:
SPP-like connection-based secured data transmission: The Proteus-III firmware implements
an SPP-like Bluetooth
several Proteus-III and/or to other Bluetooth
profile. Any module in the network can initiate a connection setup. Secured connections
allow the transmission of encrypted data.
Remote GPIOs: The Proteus-III firmware allows to switch free module GPIOs via remote con-
trol. More information can be found in chapter 11 .
Advanced customization capabilities: The configurable Device Information Service (DIS),
the UUID and the appearance of the Bluetooth
Proteus-III to fuse with the user's end product.
Low power position sensing solutions: The current TX power of any Proteus-III is always
transmitted with each advertising packet when the module is in command mode. With
this, distance estimation and position sensing solutions can be realized conveniently by
performing a passive scan.
Fast serial interface: The Proteus-III offers a UART-interface to communicate with a host us-
ing a user-defined baud rate and a simple command interface.
Latest microprocessor generation provided by Nordic Semiconductor nRF52 series: The
heart of the Proteus-III is a Bluetooth
mance values combined with low power consumption. It is a 32 Bit ARM Cortex-M4F
CPU with 1024 kB flash + 256 kB RAM and up to 8 dBm output power.
®
Bluetooth 5 stack: The Bluetooth
sion using state-of-the-art technology of Nordic Semiconductors.
High throughput mode: The Proteus-III 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 [2].
®
All Bluetooth LE roles supported: The integrated Bluetooth
®
Bluetooth LE roles. Depending on the current state of operation the Proteus-III firmware
automatically switches its role to execute the user's instructions.
Flexible wired interfacing: The Proteus-III is equipped with extra pins suited for custom de-
vice/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-III 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-III firmware provides the "peripheral only" operation mode
(see chapter 10 ), 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
