In recent years, with this cloud computing and large data technology, the smart home industry has also been popular with extensive attention. The popularity of the market and the popularity of consumer concepts are constantly promoting the progress of the industry. The product is diverse, and the characteristics are different. This program is intelligent to control smart bulb, smart lock and smoke detectors through mobile applications with QCA4020 development kits. Equipment, display home automation.
Be
The main goal is to develop design home automation solutions to QCA4020 to control smart devices (such as smart bulb opening, smart lock switches and smoke detectors). These devices are controlled by the application installed on smartphones. The following is Some reasons for using QCA4020.
1, QCA4020 provides three-mode communication, Wi-Fi, BLE 5 and 802.15.4 technology, including Zigbee and Thread
2, multi-core CPU. Application processor Cortex M4F, Network Protocol Processor Cortex M0, Tensilica Xtensa WiFi dedicated processor to provide a multi-range multi-RS solution.
3, integrate multiple IoT ecology, preset AWS SDK and Azure SDK. Confused the mainstream program in the country.
4. Support hardware security features, improve device protection levels, including Secure Boot, Secure Boot, Hardware Crypto Engines, Storage Security, Debug Security With LifeCyle Control, Key Provisioning and Wireless Protocol Security.

1.4 deploying application
1.4.1 Preparation before burning, enter the 4020 development plate into the EDL mode, as shown below. First, the J34's PIN1 is shorted, and the J57's PIN2 is shorted. OSB connected J6, and then powered.
1.4.2 When the USB is connected to the computer, it will enter the EDL mode. After the device manager sees the following QUALCOMM HS-USB QDLoader 9008 (COM5), it can perform the burning command. (Where COM5 has different equipment Display)
