Dual-mode Bluetooth module is secure for industrial IoT

Strong security for the industrial IoT is a feature of the compact Nina-B2 Bluetooth standalone module, released by u-blox.

The Nina-B2 dual-mode Bluetooth 4.2 stand-alone module has an integral secure boot and wide temperature ranges. Pre-flashed with u-blox connectivity software which supports beacon, GATT client, GATT server, and serial port options, Nina-B2 is configured by using AT commands over UART, without requiring extensive knowledge of the Bluetooth protocol, says u-blox. It has already been tested and certified globally, and reduces development costs and speeds time to market, explains the company.

Nina-B2’s secure boot guarantees that the software is authenticated by u-blox, for a secure operating environment for the Bluetooth module.

As the module is equipped with dual-mode Bluetooth capability, it can simultaneously manage Bluetooth low energy and Bluetooth BR/EDR connections. This allows it to connect to legacy devices.”

Nina-B2 measures 10 x 10.6 x 2.2mm (without antenna) and 10 x 14 x 3.8mm (with antenna). It is pin-compatible with the u-blox Nina family, allowing it to be easily swapped in or out with other Nina modules, with their different radio technologies such as Bluetooth low energy and Wi-Fi.

The module can be used for industrial automation, such as machine control devices, industrial terminals and products for remote control. Possible applications also include wireless-connected and configurable equipment, point of sale, telematics, and health devices.

Nina-B2 is expected to go into production in summer 2018.

Swiss company, u-blox, provides positioning and wireless communication technologies for the automotive, industrial, and consumer markets. The company’s portfolio enables people, vehicles, and machines to determine their precise position and communicate wirelessly over cellular and short range networks.

The company’s chips, modules, and a growing ecosystem of product support data services. Its headquarters are in Thalwil, Switzerland, and the company has offices in Europe, Asia, and the USA.
