BL602&BL604综合项目1：Dohome智能全彩灯具

通过BL602/BL604芯片作为系统主控，实现智能全彩灯的控制，可通过wifi接入Dohome平台，同时DoHome APP已经对接了各大智能音箱（小米小爱，百度小度，阿里天猫精灵，Amazon，Google，京东叮咚）。可根据需求通过BL602模组制作智能灯具和其他相关产品。

在app_config.h中定义了软件的版本号，开发板产生的热点名，我们需连接通信的DoHome服务器，和我们udp,tcp通信使用的端口号，以及使用到的IO口：

为了稳定的配网，此方案使用ap配网，通过连接开发板产生的热点，手机app把路由器wifi名称密码发送给开发板完成配网：

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;
}

连上服务器后开始发送心跳包：

static void vTimerCallback(TimerHandle_t timer)
{
    //服务器连接上了,开始发送心跳
    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
", 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=====");
    }
}

处理下发的数据进行设备控制：

/*
    处理tcp服务下发的数据
 */
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");
    }
}

将程序编译好后烧录到芯片中，手机下载Dohome APP，添加设备，按提示进行设备的配网

1.扫码下载APP

 2.进入APP点击右上角添加设备，选择彩色灯

 3.按APP提示进行配网

4.添加设备成功，能从Dohome  APP控制设备

配网成功后，可使用app控制，也可以绑定智能音箱控制。
