TIDA-010007
描述This reference design showcases integrating Wi-Fi® capability to enhance connectivity in grid equipment for asset monitoring using the CC3220 device, SimpleLink Wi-Fi and IoT, single chip wireless MCU with integrated network processor and applications processor. The design enables the capability to setup a Wi-Fi network or connect to an external network, transfer data and optimize power. Data transfer scheme includes sending/receiving control, status, settings, firmware updates over the air between devices or to the cloud. Switching the device between always connected, intermittently connected, and hibernate mode optimizes power consumption for grid applications.
特性- Wi-Fi Connectivity: Wi-Fi radio with integrated network processor and applications processor (ARM® Cortex®-M4) for internet of things (IoT) integration into industrial and residential equipment
- Single system-on-chip (SoC) optimized for performance and size
- Chip-level, Wi-Fi Alliance Wi-Fi® CERTIFIED™
- Provisioning made easy with SmartConfig™ in addition to application point (AP) provisioning
- System architecture:
- Two connection schemes: Connection to external AP (device as STA), device as AP
- Data transfer schemes: Always connected, intermittently connected
- Power consumption: Optimized for wired and battery operation
- Always Connected: <700 μA (Beacon only)
- Intermittently Connected: <3 mA (5 s interval), <1.5 mA (10 s interval)
- Device low power modes: Hibernate ( < 10 μA), LPDS (<150 μA, 20 mA peak)
- Security features:128-bit unique device ID, secure boot of MCU image, internal HTTPS server for AP provisioning, MQTT over TLS, secure over-the-air (OTA) update
