android - 无法将 BLE 连接到 Android 应用程序

Question

我刚买了一个带有CC2541芯片的蓝牙HM-10模块。我用 Arduino Uno 为它供电。我用手机（三星 j3，2016）扫描了蓝牙设备，发现模块名为 BT05。我将设备配对，但无法将蓝牙模块与任何应用程序连接。我尝试将它与AMR Voice/BT Voice Control 应用程序和LED 控制器连接。我用于通过应用程序控制 LED 的代码来自这里：create.arduino.cc/projecthub/user206876468/arduino-bluetooth-basic-tutorial-d8b737

我也把代码放在这里：

char data = 0;            //Variable for storing received data
void setup()
{
Serial.begin(9600);   //Sets the baud for serial data transmission                               
pinMode(13, OUTPUT);  //Sets digital pin 13 as output pin
}
void loop()
{
if(Serial.available() > 0)      // Send data only when you receive data:
{
  data = Serial.read();        //Read the incoming data & store into data
  Serial.print(data);          //Print Value inside data in Serial monitor
  Serial.print("\n");        
  if(data == '1')              // Checks whether value of data is equal to 1
     digitalWrite(13, HIGH);   //If value is 1 then LED turns ON
  else if(data == '0')         //  Checks whether value of data is equal to 
  0
     digitalWrite(13, LOW);    //If value is 0 then LED turns OFF
 }
 }

这些是我得到的错误：

Answer 1

也许您可以尝试它是否有效并自己更改代码

#include <SoftwareSerial.h> 

SoftwareSerial BT(2, 3); //RX, TX

char val;

void setup() {

Serial.begin(9600);  
BT.begin(9600);
Serial.println("BT is ready!");  

}

void loop() {
if (BT.available()>0) {
    val = BT.read();
    Serial.print(val);
  }
}
