Dual-mode Bluetooth module features strong security for the IIoT

Already tested and certified globally, it also reduces development costs and speeds time to market.

NINA-B2's built-in secure boot 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," said 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 10x10.6x2.2mm (without antenna) and 10x14x3.8mm (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 WiFi.

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.
