BL602&BL604綜合項目1：Dohome智能全彩燈具

通過BL602/BL604芯片作為系統主控，實現智能全彩燈的控制，可通過wifi接入Dohome平台，同時DoHome APP已經對接了各大智能音箱（小米小愛，百度小度，阿里天貓精靈，Amazon，Google，京東叮咚）。可根據需求通過BL602模組制作智能燈具和其他相關產品。

在app_config.h中定義了軟件的版本號，開發板產生的熱點名，我們需連接通信的DoHome服務器，和我們udp,tcp通信使用的端口號，以及使用到的IO口：

為了穩定的配網，此方案使用ap配網，通過連接開發板產生的熱點，手機app把路由器wifi名稱密碼發送給開發板完成配網：

int wifi_setup_ap(void)
{    
    LOGI(TAG, "wifi_setup_ap");
    char def_ap_ssid[33] = {"BL602_AP"};
    memset(def_ap_ssid, 0x00, sizeof(def_ap_ssid));
    get_default_ssid(def_ap_ssid);

    wifi_interface_t wifi_interface_ap = wifi_mgmr_ap_enable();
    dhcpd_set_server_gw("192.168.4.1");
    wifi_mgmr_ap_start(wifi_interface_ap, def_ap_ssid, 0, NULL, 1);
    return 1;
}

 

連上服務器后開始發送心跳包：

static void vTimerCallback(TimerHandle_t timer)
{
    //服務器連接上了,開始發送心跳
    if (b_start_keep_alive) {
        char keep_msg[256];
        memset(keep_msg, 0x00, sizeof(keep_msg));
        sprintf(keep_msg, "cmd=keep&device_id=%s&device_key=%s\r\n", dev_id, dev_key);
        send(g_client_fd, keep_msg, strlen(keep_msg), 0);
        LOGI(TAG, "keepalive buff: %s", keep_msg);
    } else {
        // LOGI(TAG, "tcp client disconnect=====");
    }
}

處理下發的數據進行設備控制：

/*
    處理tcp服務下發的數據
 */
static void parse(int socket, char *buff, int len)
{
    // LOGI(TAG, "tcp_package: %s", buff);
    if (strstr(buff, "cmd=subscribe") != NULL) {
        char *pstart = strstr(buff, "res=");
        if (pstart != NULL) {
            pstart += strlen("res=");
            int r = *pstart - '0';
            if (r == 1) {
                LOGI(TAG, "register device on remote server OK");
            } else {
                LOGI(TAG, "register device failed!");
            }
        } else {
            LOGI(TAG, "result not found!");
        }
    } else if (strstr(buff, "cmd=publish") != NULL) {
        char *pstart = strstr(buff, "message=");
        if (pstart != NULL) {
            pstart += strlen("message=");
            char ret_buf[256];
            parse_dohome_protocol(pstart, len - (pstart - buff), ret_buf);
        } else {
            LOGI(TAG, "message not found!");
        }
    } else if (strstr(buff, "cmd=keep") != NULL) {
        LOGI(TAG, "send heartbeat OK");
    } else {
        LOGI(TAG, "no such command");
    }
}

將程序編譯好后燒錄到芯片中，手機下載Dohome APP，添加設備，按提示進行設備的配網

1.掃碼下載APP

 

 2.進入APP點擊右上角添加設備，選擇彩色燈

 

 3.按APP提示進行配網

 

 

4.添加設備成功，能從Dohome  APP控制設備

 

 

配網成功后，可使用app控制，也可以綁定智能音箱控制。
