Wi-Fi Quick Get-Started
在 projects/examples/wifi 目录中提供了三种Wi-Fi常见使用场景的Example Demo，客户可以根据Demo快速了解Wi-Fi的相关使用.
ap
scan
sta_connect
备注
上述三种Demo编译下载后，可实现开机自动开启SoftAP、自动扫描、自动连接的功能
AP/SoftAP
AP Example Demo展示了使用Beken Wi-Fi芯片建立SoftAP的流程.
编译命令:
make bk7256 PROJECT=examples/wifi/ap文件路径:
build/ap/bk7256/all-app.bin参数配置:
projects/examples/wifi/ap/main/Kconfig.projbuild
menu "Example Configuration"
config EXAMPLE_WIFI_SSID
string "WiFi SSID"
default "myssid" //SoftAP SSID
config EXAMPLE_WIFI_PASSWORD
string "WiFi Password"
default "12345678" //SoftAP Password
config EXAMPLE_IP
string "IP4 Address of AP"
default "192.168.10.1" //Default IP Address
config EXAMPLE_MASK
string "Network mask of AP"
default "255.255.255.0" //Default参数可以自定义
config EXAMPLE_GW
string "Gateway address of AP"
default "192.168.10.1"
config EXAMPLE_DNS
string "DNS address of AP"
default "192.168.10.1"
endmenu
main log

Scan
Scan Example Demo介绍了Wi-Fi扫描的基本流程，包含全信道扫描和指定SSID扫描.
编译命令:
make bk7256 PROJECT=examples/wifi/scan文件路径:
build/scan/bk7256/all-app.bin参数配置:
projects/examples/wifi/scan/main/Kconfig.projbuild
menu "Example Configuration"
config EXAMPLE_SCAN_ALL_SSID
bool "Scan All SSID"
default y //全信道扫描
config EXAMPLE_WIFI_SSID
string "WiFi SSID"
depends on !EXAMPLE_SCAN_ALL_SSID
default "aclsemi" //指定SSID扫描
endmenu
main log
wifi:I(1134):scan found 4 AP //指定SSID扫描

sta_connect
sta_connect通过提前配置SSID、Password，编译成功后烧录版本，可实现开机自动连接功能.
编译命令:
make bk7256 PROJECT=examples/wifi/sta_connect文件路径:
build/sta_connect/bk7256/all-app.bin配置参数:
projects/examples/wifi/sta_connect/main/Kconfig.projbuild
menu "Example Configuration"
config EXAMPLE_WIFI_SSID
string "Wi-Fi SSID"
default "aclsemi" //目标SSID
config EXAMPLE_WIFI_PASSWORD
string "Wi-Fi Password"
default "ACL8semi" //目标SSID密码
endmenu
main log
wifi:I(308):wifi inited(1) ret(0) //开机后初始化完成
example:I(310):ssid:aclsemi password:ACL8semi //连接指定SSID、Password
example:I(3618):STA connected to aclsemi //连接成功
example:I(3658):STA got ip //获取IP地址
备注
客户编译命令需指定相应PROJECT和PROJECT_LIBS make bk7256 PROJECT=examples/wifi/sta_connect PROJECT_LIBS=bk7256_app
