HM-10和Arduino-发送不带代码结尾的AT命令

问题描述

我需要将HM-10与Arduino Uno或Nano一起使用.我无法弄清楚如何发送AT命令并阅读回复.这些命令可通过串行监视器运行，而不能通过代码运行.

I need to use HM-10 with Arduino Uno or Nano.I'm not able to figure out how to send AT commands and read the reply.The commands work from serial monitor, but not from code.

这是我到目前为止尝试过的:

Here's what I've tried so far:

#include <SoftwareSerial.h>

SoftwareSerial blueToothSerial(0,1); // RX, TX

void setup()
{
  // Open serial communications and wait for port to open:
  Serial.begin(115200);
  Serial.println("Serial began");
  blueToothSerial.begin(9600);
  delay(2000);
}

void loop()
{
  Serial.println("looping...");
  blueToothSerial.print("AT+DISC?");
  delay(5000);
  if (blueToothSerial.available())
  {
    Serial.println("bluetooth serial available");
    Serial.write(blueToothSerial.read());
  }
}

但是，我看不到任何回复，我感觉命令没有触发.执行不会进入if(blueToothSerial.available())

However, I'm not able to read any reply, I feel the command is not firing. The execution doesnt go inside if(blueToothSerial.available())

推荐答案

确保在串行监视器选项中设置noth NL& CR.

Make sure you set noth NL&CR in the serial monitor options.
