无法沟通：Arduino与蓝牙HC-06

Question

我写了一个程序，可以通过连接到Arduino Uno的DHT11传感器捕获水分。捕获的值将使用蓝牙HC-06模块发送到Android应用程序。一切正常，但后者（HC-06）不会发出捕获的水分。

有人可以帮助我，谢谢你 代码如下：

#include <SoftwareSerial.h>
/* to communicate with the Bluetooth module's TXD pin */
#define BT_SERIAL_TX 10
/* to communicate with the Bluetooth module's RXD pin */
#define BT_SERIAL_RX 11
/* Initialise the software serial port */
SoftwareSerial BluetoothSerial(BT_SERIAL_RX, BT_SERIAL_TX);

// DHT-11 Configuration
#include <DHT.h> // lightweight DHT sensor library
#define DHTTYPE DHT11 // DHT 11
#define TEMPTYPE 0 // Use 0 for Celsius, 1 for Fahrenheit
#define DHTPIN 2
DHT dht(DHTPIN, DHTTYPE); // Define Temp Sensor

void setup() {
  BluetoothSerial.begin(115200); // Initialise BlueTooth
  Serial.begin(9600);
  //delay(1000);
  dht.begin(); // Initialize DHT Teperature Sensor
  BluetoothSerial.print("Starting ...");
}

void loop() {
  // Take readings
  float h = dht.readHumidity(); // Read humidity
  BluetoothSerial.println(h);
  delay(500);
}
