Function features
2.1
Overview
RAK477 module is a Wi-Fi module that fully compliant with IEEE 802.11b/g/n
wireless standards, It combines an ARM-CM3 MCU, WLAN MAC, a 1T1R capable
WLAN baseband, and RF in the module. It have onboard antenna, and external
antenna interface, RF output PIN also exist in the board. RAK477 internally
integrated TCP / IP protocol stack, supporting numerous protocols such as ARP, IP,
ICMP, TCP, UDP, DHCP CLIENT, DHCP SERVER, DNS and other etc. It supports AP
mode, STA mode, AP+STA mode. It support rich AT command for all kinds of
application, Users can easily and quickly use it to wifi networking and data
transmission. It also support transparent transmission, easy to use by simply using
the PC, APPs tool to work individually or in bulk for parameters configuration, and
then module connects the serial ports and network for normal usage. The baud rate
of module serial port is up to 921600bps, which can fully meet the low-rate
applications.
In network part, RAK477 supports storing network parameters in the module, and
reduce time connect to network. The module supports wireless network parameters
configuration, supports wireless firmware upgrade. It also supports EasyConfig.
It also provides a bunch of configurable GPIOs which are configured as SPI ,UART,
I2C, for different applications and control usage. RAK477 integrates internal 512K
SRAM and 1MB flash for complete WIFI protocol functions.
