Most smart thermostat designers want to design a low-power, connected, microcontroller (MCU)-based smart thermostat that can securely connect a variety of sensors to the cloud for remote monitoring and control. The TIDM-1020 reference design provides a software reference for implementing such a smart thermostat, using the CC3220 device as the main MCU and providing Wi-Fi connectivity. This application note details how to add Bluetooth Low Energy (BLE) connectivity configuration to the TIDM-1020.

This reference design is intended for thermostat end-equipment developers, engineers, and system evaluators. The design provides reference code to demonstrate how to integrate the CC3220SF device into a variety of analog and digital sensors, cloud-connected services, human-machine interfaces (HMIs), passive infrared (PIR) sensors, and external relay controls. The reference design is also designed to showcase: low-power connectivity to the Internet and cloud, remote control and programming, remote monitoring of data, and secure over-the-air (OTA) updates of device and application firmware.
