STA Connect
Project Overview
This project is used for demonstrating [STA connect](https://docs.bekencorp.com/armino/bk7236/en/latest/developer-guide/wifi/bk_wifi_mode.html)
This project shows the process of connecting BEKEN Wi-Fi module as STA to AP.
By configuring ssid and password in advance, sta_connect could achieve connect automatically after startup.
Hardware Requirements
All Beken development board.
Configure and Build
Configure the Project
You can configure ssid and password in projects/examples/wifi/sta_connect/main/Kconfig.projbuild
menu "Example Configuration"
config EXAMPLE_WIFI_SSID
string "WiFi SSID"
default "TP-LINK_599F"
help
SSID (network name) for the example to connect to.
config EXAMPLE_WIFI_PASSWORD
string "WiFi Password"
default "12345678"
help
WiFi password (WPA or WPA2) for the example to use.
endmenu
Build
Enter the following command in the Armino root directory to compile:
> make bk7236 PROJECT=examples/wifi/sta_connect
For preparations such as toolchain installation, please refer to [Quick Start](https://docs.bekencorp.com/armino/bk7236/en/latest/get-started/index.html).
Connect UART
UART0 is used for:
BKFIL to download images
Logging and CLI of Non-secure world
UART1 is used for logging of secure world.
Flash all-app.bin
Burn Armino/build/sta_connect/bk7236/all-app.bin to the board using BKFIL.
Running and Output
Restart the development board to observe the sta_connect process.
