u-blox, a global provider of leading positioning and wireless communication technologies, announced the NINA-B4 Bluetooth low energy module series. Based on Nordic Semiconductor's nRF52833 chip, NINA-B4 enables a number of Bluetooth features including Bluetooth long range, Bluetooth mesh, and Bluetooth direction finding. The module is fully tailored to the needs of applications in the connected industry, smart homes, buildings, and cities, asset tracking, and eHealth.

The main highlight of the NINA-B4 series is Bluetooth's new direction finding feature, a key component of the Bluetooth v5.1 specification that brings the benefits of high precision positioning to indoor applications. NINA-B4 is the first u-blox module designed to act as both a transmitter and a receiver in angle of arrival (AoA) and angle of departure (AoD) direction finding and indoor positioning applications.

In AoA-based implementations, stationary beacons based on NINA-B4 selects the antenna in multi-antenna array and determine the angle of arrival of signals emitted by a tracking device to pinpoint the tracker's location with sub-meter level accuracy. When AoD is used, the NINA-B4 based tracking device triangulates its position by calculating the angle of departure of signals from the stationary Bluetooth beacons' multi-antenna arrays.

Mesh, long range, and extended temperature range

The u-blox NINA-B4 enables wireless mesh networks, which offer robust communication between large numbers of connected devices, extending the reach of messages by relaying them from node to node until they reach their destination. By simplifying the control of groups of devices, mesh networks are well suited for applications such as smart lighting systems in cities and buildings, which further benefit from the module's enhanced operating temperature range (up to 105 C).

Featuring Bluetooth long range, the NINA-B4 series is ideal for deployments in harsh environments, e.g. to enable wirelessly connected and configurable equipment. Long range not only increases the distance that Bluetooth signals can travel, it also makes communications more robust and reliable in unfavorable ones, common in production plants or on factory floors.

The NINA-B4 series comes with the u-blox u-connect software, simplifying the integration of Bluetooth into new and existing products by providing an easy-to-use interface to configure the connectivity required.

NINA-B4 further stands out for its powerful Arm(R) Cortex(R)-M4F MCU with an open CPU architecture, allowing customers to run their own applications right on the module. Supporting Zigbee and Thread, the first members of the NINA-B4 family come with an internal PCB antenna, or alternatively, with a U.FL connector for an external antenna of choice.

Engineering samples of the NINA-B4 will be available in December 2019.
