基于blinker,用小爱温湿度查询,程序为何不进入case语句中?
我用DHT11做的温湿度计,但是小爱同学一直读取的是switch中的default部分,这是为什么呢?#define BLINKER_WIFI
#define BLINKER_MIOT_SENSOR
#include <Blinker.h>
#include <DHT.h>
char auth[] = "4a4961b42827";
char ssid[] = "ChinaNet-wxM3";
char pswd[] = "2nm9r5w6";
BlinkerNumber HUMI("humi");
BlinkerNumber TEMP("temp");
#define DHTPIN D3
#define DHTTYPE DHT11 // DHT 11
//#define DHTTYPE DHT22 // DHT 22(AM2302), AM2321
//#define DHTTYPE DHT21 // DHT 21 (AM2301)
DHT dht(DHTPIN, DHTTYPE);
float temp_read = 0;
int8_t humi_read = 0;
void miotQuery(int32_t queryCode)//用户自定义设备查询的回调函数
{
BLINKER_LOG("MIOT Query codes: ", queryCode);
switch (queryCode)
{
// case BLINKER_CMD_QUERY_PM25_NUMBER :
// BLINKER_LOG("MIOT Query PM25");
// BlinkerMIOT.pm25(20);
// BlinkerMIOT.print();
// break;
case BLINKER_CMD_QUERY_HUMI_NUMBER :
BLINKER_LOG("MIOT Query HUMI");
BlinkerMIOT.humi(humi_read);
BlinkerMIOT.print();
break;
case BLINKER_CMD_QUERY_TEMP_NUMBER :
BLINKER_LOG("MIOT Query TEMP");
BlinkerMIOT.temp(temp_read);
BlinkerMIOT.print();
break;
// case BLINKER_CMD_QUERY_TIME_NUMBER :
// BLINKER_LOG("MIOT Query Time");
// BlinkerMIOT.time(millis(20));
// BlinkerMIOT.print();
// break;
default :
BLINKER_LOG("小爱查询了默认数据");
BlinkerMIOT.temp(temp_read);
BlinkerMIOT.humi(humi_read);
// BlinkerMIOT.pm25(20);
// BlinkerMIOT.co2(20);
BlinkerMIOT.print();
break;
}
}
void heartbeat()
{
HUMI.print(humi_read);
TEMP.print(temp_read);
}
void setup()
{
Serial.begin(115200);
BLINKER_DEBUG.stream(Serial);
BLINKER_DEBUG.debugAll();
pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, LOW);
Blinker.begin(auth, ssid, pswd);
Blinker.attachHeartbeat(heartbeat);
BlinkerMIOT.attachQuery(miotQuery);
dht.begin();
}
void loop()
{
Blinker.run();
int8_t h = dht.readHumidity();
float t = dht.readTemperature();
if (isnan(h) || isnan(t))
{
BLINKER_LOG("Failed to read from DHT sensor!");
}
else
{
BLINKER_LOG("Humidity: ", h, " %");//blinker串口打印函数
BLINKER_LOG("Temperature: ", t, " *C");
BLINKER_LOG("----------------");
humi_read = h;
temp_read = t;
}
Blinker.delay(2000);
}
貌似因为小爱发来的就是全部查询指令 Humidity: 93 %
Temperature: 18.40 *C

小爱查询了默认数据

...OK!

为什么小爱查询温度和湿度的MIOT Query codes都是0呢? :'(一直以为我看不懂串口监视器,群里还有人说我缺少自定义宏。终于看到原来小爱反馈的就都是“0”,不过我通过测试多插孔模式,用void miotQuery(int32_t queryCode,int num)查询不同插孔状态,查询几号插孔num就返回数字几。
