本节实现WIFI的连接,本节的例程可参考后面的TCP CLIENT或者TCP SERVER 的相关例程
TCP CLIENT地址:
https://github.com/SmartArduino/Doiting_BL/tree/master/examples/WIFI_CLIENT
WIFI_CLIENT TCP SERVER地址:
https://github.com/SmartArduino/Doiting_BL/tree/master/examples/WIFI_SERVER
系统初始化:
void user_main(void){ wifi_init(wifi_event_handler); wifi_setup_sta(); }
WIFI初始化相关函数:
/* wifi初始化 */ void wifi_init(wifi_event_cb_t user_wifi_event_cb) { LOGI(TAG, "wifi init"); cmd_stack_wifi(NULL, 0, 0, NULL); static_wifi_cb = user_wifi_event_cb; void wifi_set_event_cb(void (*user_wifi_cb)(input_event_t *event, void *private_data)); wifi_set_event_cb(event_cb_wifi_event); }
static void cmd_stack_wifi(char *buf, int len, int argc, char **argv) { /*wifi fw stack and thread stuff*/ static uint8_t stack_wifi_init = 0; if (1 == stack_wifi_init) { puts("Wi-Fi Stack Started already!!!\r\n"); return; } stack_wifi_init = 1; printf("Start Wi-Fi fw @%lums\r\n", bl_timer_now_us()/1000); hal_wifi_start_firmware_task(); /*Trigger to start Wi-Fi*/ printf("Start Wi-Fi fw is Done @%lums\r\n", bl_timer_now_us()/1000); aos_post_event(EV_WIFI, CODE_WIFI_ON_INIT_DONE, 0); }
/* wifi连接状态 */ void wifi_event_handler(wifi_event_indicate_t event){ switch (event) { case WIFI_EVENT_CONNECT: LOGE(TAG, "wifi_connect"); break; case WIFI_EVENT_DISCONNECT: LOGE(TAG, "wifi_disconnect"); break; default: LOGE(TAG, "wifi_event: %d",event); break; } }
static void event_cb_wifi_event(input_event_t *event, void *private_data) { switch (event->code) { case CODE_WIFI_ON_DISCONNECT: { LOGI(TAG, "wifi disconnect"); if(static_wifi_connect_status != 0){ static_wifi_connect_status = 0; if(static_wifi_cb != NULL){ static_wifi_cb(WIFI_EVENT_DISCONNECT); } } } break; case CODE_WIFI_ON_CONNECTED: { LOGI(TAG, "wifi connect"); } break; case CODE_WIFI_ON_GOT_IP: { LOGI(TAG, "wifi get ip"); if(static_wifi_connect_status != 1){ static_wifi_connect_status = 1; if(static_wifi_cb != NULL){ static_wifi_cb(WIFI_EVENT_CONNECT); } } } break; } }
Wifi连接成功后会输出连接的相关信息
