Bluetooth module offers strong security for the Industrial IoT

April 19, 2018 // By Jean-Pierre Joosting
Swiss company, u-blox has announced the NINA-B2 dual-mode Bluetooth® 4.2 stand-alone module, enabling industrial IoT applications thanks to its built-in secure boot and wide temperature ranges.

Pre-flashed with u-blox connectivity software which supports many common use cases such as Beacon, GATT client, GATT server, and serial port, NINA-B2 is configured easily using AT commands over UART, without requiring deep knowledge of the Bluetooth protocol. Already tested and certified globally, it also reduces development costs and speeds time to market.

NINA-B2 features built-in secure boot that guarantees that the software is authenticated by u-blox and has therefore not been tampered with. This provides a secure operating environment for the Bluetooth module.

"As the IoT progresses and Bluetooth is a key wireless technology, security and backwards-compatibility remain key challenges," says Stefan Berggren, Senior Product Marketing Manager, Product Center Short Range Radio at u-blox. "NINA-B2 provides top-grade security through its unique secure boot operating environment. As it is equipped with dual-mode Bluetooth capability, it can simultaneously manage Bluetooth low energy and Bluetooth BR/EDR connections, making it ideal to connect to legacy devices."

NINA-B2 is very compact, at 10- x 10.6- x 2.2-mm (without antenna) and 10- x 14- x 3.8-mm (with antenna). Most of the Bluetooth modules at this scale are single-mode Bluetooth low energy or Bluetooth BR/EDR devices. NINA-B2's size makes it an easy fit in any IoT device. It is also 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.

Apart from 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 slated to go into production in summer 2018.
