Bluetooth Mesh

Complete solution

For developing your Bluetooth Mesh product

Mesh

If you are developing a Bluetooth Mesh product it is wise to evaluate what the #1 supplier of Bluetooth Low Energy System-on-Chips (SoCs) offers, as Bluetooth Mesh is built on top of Bluetooth LE.

We offer a broad portfolio of SoCs supporting Bluetooth Mesh. The SoCs have different memory sizes and capabilities, enabling you to select the perfect match for your product's requirements. Complementing our SoCs, we offer development hardware, software, and tools to make it easy for you to build your product, while also reducing time-to-market. We offer a qualified Bluetooth Mesh stack with all mandatory and selected optional features supported, in addition to a wide range of application models and samples for lighting and sensor networks. Use this as a foundation to build on top of. We also offer a mobile app, nRF Mesh, available as free source code for both iOS and Android. This is a great starting point for your own app. The app can be used to provision, configure, and control Mesh nodes in evaluation and test.

We offer our excellent technical support to anyone developing a Bluetooth Mesh product with one of our SoCs. We guide you through the whole product development process.

Advanced Bluetooth Mesh SoCs

Four of the seven SoCs in the nRF52 Series support Bluetooth Mesh. All four integrate a powerful yet efficient 64 MHz Arm Cortex-M4 CPU. Flash memory size ranges from 256 KB to 1024 KB while RAM size ranges from 32 KB to 256 KB. The nRF52 Series offers simpler cost-effective options and highly advanced options, all with ultra-low power consumption. The nRF52 Series is truly the ideal platform for basing a product portfolio upon. The similar hardware and software architecture results in excellent software portability, increasing software reusability and lowering time-to-market and development cost.

The nRF5340 SoC is our Bluetooth Low Energy flagship. It is the world’s first wireless SoC with two Arm® Cortex®-M33 processors. The combination of two flexible processors, up to 105 °C operating temperature and advanced security features make it the perfect choice for Bluetooth Mesh applications such as professional lighting, sensor networks, and asset tracking. The nRF5340 is an all-in-one SoC, including a superset of the most prominent nRF52 Series features. Features like Bluetooth 5.4, high-speed SPI, QSPI, USB, and more, are combined with more performance, memory, and integration, while minimizing current consumption. It also offers security features such as trusted execution, root-of-trust, and secure key storage.

The nRF52 and nRF53 Series are all-flash based SoCs. Flash memory brings complete flexibility and upgradability to your products. They can be re-programmed in the factory or in the field with over-the-air device firmware upgrades (OTA DFU). This enables product updates and feature additions any time, anywhere.

Supported supplementary products

nPM1300 PMIC

Power Management IC (PMIC) with unique system management features

The nPM1300 is designed to provide highly efficient power regulation for Nordic’s nRF52 and nRF53 Series, as well as the nRF54L and nRF54H Series wireless multiprotocol Systems-on-Chip (SoC). The PMIC is also suitable for battery charging for applications based on the nRF91 Series systems-in-package (SiPs) for cellular IoT, by using the PMIC’s unregulated output to power the SiP's internal buck regulators.

Devices using the nPM1300 and a compatible SoC or SiP also get access to the Nordic Fuel Gauge, a highly accurate, ultra-low-power way of estimating state-of-charge of rechargeable batteries.

Concurrent Bluetooth Mesh and Bluetooth LE

All Bluetooth Mesh SoCs can run both Bluetooth Low Energy and Bluetooth Mesh concurrently. The radio time is time sliced and shared between the protocols. The scheduling is autonomous and connections are maintained. Leverage the interoperability of our Bluetooth LE stack and let a Bluetooth LE device, such as a smartphone, bridge into the Bluetooth Mesh network. The smartphone can then provision/commission in new nodes and interact with the mesh network.
