HM-10和Arduino-发送不带代码结尾的AT命令 [英] HM-10 and Arduino - Sending AT commands with no line ending from code

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.
