This reference design empowers design engineers to quickly prototype and develop modular, reusable options for multi-node Bluetooth LE connectivity.

This answer by Mircochip Expertise highlights a wi-fi thermostat software that mixes Bluetooth LE 5.2 and Wi-Fi applied sciences to facilitate the real-time assortment, management, and monitoring of temperature knowledge. By integrating a PIC32CZ CA microcontroller-based gateway and RNBD451 Bluetooth LE modules, it ensures seamless communication between nodes and the cloud. This integration not solely simplifies growth for engineers but additionally accelerates time to market.

This reference design gives a number of benefits. It permits engineers to shortly transition from idea to prototype via its modular design, which can also be expandable and reusable throughout completely different instruments. It helps multi-link Bluetooth LE and Wi-Fi integration utilizing the PIC32CZ CA microcontroller and offers cloud-enabled monitoring with AWS IoT, streamlining superior analytics. By leveraging MPLAB Concord 3 libraries, the answer reduces prices and growth time, making it extremely environment friendly.

The Bluetooth LE gateway on this design acts as a bridge, connecting Bluetooth LE gadgets to bigger community infrastructures just like the cloud. It performs important capabilities, together with knowledge assortment from sensors and wearables, transmitting knowledge to cloud servers for processing, enabling distant monitoring, and translating protocols between Bluetooth LE and different networks like Wi-Fi or Ethernet. This versatile design helps numerous use instances, similar to connecting and controlling gadgets in sensible properties (e.g., thermostats and lighting), facilitating affected person monitoring via wearables in healthcare, gathering knowledge from industrial IoT sensors, and enhancing stock administration and buyer monitoring in retail environments.

This wi-fi thermostat reference design includes a central management panel (PIC32CZ_CA90) as the primary Bluetooth LE node, connecting to 2 peripheral nodes by way of RNBD451 modules. It requests and shows temperature knowledge on a maXTouch graphics show and sends it to the WFI32 IoT gateway for AWS cloud monitoring. The primary peripheral node (PIC32CM_LS60) acts as a GATT server, updating temperature knowledge and triggering LED alerts for threshold breaches. The second node (WBZ451) reads temperature from an MCP9700A sensor and triggers LED alerts for breaches. The design gives low energy consumption, scalability, and suppleness for wi-fi thermostat functions throughout industries.
