Product Description
RF-WM-3220B1 is a Wi-Fi IoT module built on basis of TI CC320SF IC, which is embedded with a Cortex-M4 MCU. It supports a variety of peripherals i.e. camera interface, I2S, SD/MMC, UART, SPI, I2C, ADC and GPIO. The module supports IEEE 802.11 b/g/n standards, and is able to work at Station, AP and Wi-Fi Direct modes. Antenna wise, it offers 3 options: ceramic antenna, IPEX base and antenna welding.
RF-WM-3220B1 supports TCP/IP protocols and relevant applications. It can be widely applied in a big variety of IoT scenarios i.e. home automation, home appliance control, security systems, smart energy, internet gateway, industrial control, smart metering, wireless audio, wireless doorbell and sensor networking nodes etc.
The module has two operation modes: AT Command Mode and Data Transparent Transmission Mode. With AT Command Mode, the developer can write a series of AT commands to route the transmission of the data. While in Data Transparent Transmission Mode, the modules automatically transmit the data by broadcasting the UDP packets with designated destinations. The developer or user does not have to instruct how the data transmission is routed in the latter mode. However, to switch between operation modes for the network or change the work mode of a module, the user has to use some simple AT commands to instruct the modules.
Product Features
The module which works at Station mode can exchange data between any devices in the LAN,beside it can through a router to enter the internet,and communicate among remote devices.
One module works at AP mode as TCP Server,and the other modules works at Station mode as TCP Client to communicate with it.
