BL模组的SDK文件的examples里面的例程都是用指令开启某个功能的，在实际使用过程中应该都是模组自动化执行逻辑，人为干预越少越好
首先新建一个属于自己的工程文件夹
我是将BL的SDK放在了自己间的一个文件夹里面，自己的工程文件夹和SDK同级目录，如下 SMART_HOME文件夹是我的工程文件夹
根据 Project_basic工程结构建立文件夹，当然也可以根据自己的习惯随便建立，只要最后在 CMakeLists.txt文件里面包含就可以，build文件夹无需自己建立，在后面执行 make时会自动生成，将 Project_basic文件夹内的 CMakeLists.txt、flash_prog_cfg.ini、Makefile、proj.conf四个文件复制到自己的工程：
我这边直接将 wifi和config文件一起复制过来了，主要是WiFi的初始化和对FreeRtos的移植，完成后需要将 flash_prog_cfg.ini文件里面最后部分修改成自己的工程名称，我的工程名称是 SMART_HOME
[FW]
filedir = ./build/build_out/SMART_HOME_$(CHIPNAME).bin
address = 0x10000
修改 CMakeLists.txt文件引用WiFi的头文件

sdk_set_main_file(main/main.c)
# 设置工程名称，这个配置决定了编译出来的文件名。(Set the project name, which determines the compiled file name)
get_filename_component(PROJECT_NAME ${CMAKE_CURRENT_SOURCE_DIR} NAME)
project(${PROJECT_NAME})
修改 main文件，新建 连接WiFi的线程，直接贴代码吧
#include "FreeRTOS.h"
#include "task.h"
#include "timers.h"
#include "mem.h"
#include <lwip/tcpip.h>
#include <lwip/sockets.h>
#include <lwip/netdb.h>

#include "log.h"
static TaskHandle_t wifi_test_task;
extern uint32_t sta_ConnectStatus;
static void wifi_test(void *pvParameters)
{
uint8_t ret = 0;
static char *ssid = "qop"; // TODO: 请在这里填上自己 WiFi 的名字和密码
static char *password = "pzypzy888888"; // TODO: 请在这里填上自己 WiFi 的名字和密码
ret = wifi_connect(ssid, password);
LOG_I("ret = %d\r\n", ret);
while (1)
{
LOG_I("[wifi_test] ================= \r\n");
vTaskDelay(10000);
}
}
int main(void)
{
board_init();
tcpip_init(NULL, NULL);
wifi_start_firmware_task();
xTaskCreate(wifi_test, "wifi_test", 1024, NULL, 15, &wifi_test_task);
vTaskStartScheduler();
while (1) {
}
}
编译
首次打开终端，进入aithinker_Ai-M6X_SDK
. install.sh
. export.sh
然后进入我们的工程文件夹执行 make
编译成功：
下载进板子后连接板子串口，使用串口助手或者PUTTY看串口日志，最后出现 CODE_WIFI_ON_GOT_IP说明WiFi连接成功。

如果移植FreeRtos使用的是 aithinker_Ai_M6X_SDK\examples\freertos\FreeRTOSConfig.h，需要修改两个地方
58行
#define configMAX_PRIORITIES (7)
修改成
#define configMAX_PRIORITIES (32)
86行
#define configTIMER_TASK_STACK_DEPTH (configMINIMAL_STACK_SIZE)
修改成
#define configTIMER_TASK_STACK_DEPTH (1024)
