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\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====="); } }
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。
