Network Gateway for Bluetooth Low Energy Mesh

As smart buildings increasingly rely on connected devices like sensors, lighting, HVAC systems, and security, the need for reliable and scalable communication frameworks has grown. Bluetooth^® Low Energy (LE) Mesh networks enable many devices to communicate efficiently over long distances without requiring significant power, making them ideal for IoT integration in building automation.

This gateway design features an MPU with a dual-core Arm^® Cortex^®-A55 CPU and is equipped with Wi-Fi and Bluetooth LE connectivity. It receives sensor data from the sensor nodes using Bluetooth LE Mesh technology. All the sensor data can be locally stored and/or streamed to the cloud for remote monitoring, sensor device health conditions can be checked and alarms/events can be triggered. The gateway has a display provision for a user interface to operate in standalone mode.

System Benefits​:

• MPU with Arm Cortex-A55 core, 1.2GHz frequency, supporting Civil Infrastructure Platform Linux (CIP Linux) for edge computing and real-time control.
• Ultra-low power Wi-Fi system-on-chip (SoC) for wireless connectivity, compliant with IEEE 802.11b/g/n specification, operating at 2.4GHz.
• High-performance, power efficient, high-throughput, and long-range Bluetooth chip, compliant with Bluetooth LE 5.0, supporting mesh networks.
• Single PMIC for stable, high-performance, and configurable power management.
• Other features include alarm and LED notifications, standalone and online modes, local storage, device provisioning, configuration settings, and secure communication.
