本文旨在用ESP8285 制作物联网灯座

交流VX：you-yu

EDA使用立创

ESP8266_RTOS-SDK

使用微信小程序控制

微信小程序部份代码

    var new_clientid = Math.random().toString(36).substr(2)
    this.setData({
      btn_loading: true
    });
    if (app.globalData.siginout == false){
      var client = new MQTT.Client("wss://" + this.data.server_addr + "/mqtt/", "clientId_" + new_clientid);
    var that = this;
    //connect to  MQTT broker
      console.log('clientid', "clientId_" + new_clientid)

灯座部份代码

char *Read_nvs_time(char* get_names)
{
    nvs_handle handle;
    static const char *NVS_CUSTOMER = "config";
    nvs_open(NVS_CUSTOMER, NVS_READWRITE, &handle);

    size_t lens = 50;
    static char time_str[50];
    //memcpy(time_str,"None",8);
    esp_err_t err = nvs_get_str(handle, get_names, &time_str, &lens);
    nvs_close(handle);
    //printf("read : %s , data: %s ,error : %d\r\n",get_names,time_str,(int)err);
    if(err != ESP_OK){
    	memcpy(time_str,"None",8);
    	return time_str;
    }else{
    	return time_str;
    }
