'''Step 3''': You need to download a Bluetooth 4.0 debugging assistant for mobile phone to connect your phone with the Bluetooth4.0 module. We've provided the tool in Android. Just download BleSerialPort.zip on your smart phone and decompress. Then you can see a file BleSerialPort. Enable Bluetooth on your phone and install the BleSerialPort.<br>
+

+
Open the installed app, as shown in Fig 1. Click icon at the top right corner. Then click the connect (Fig 2). Find HMSoft and click.<br>

+
[[File:Bleserial.png]]<br>
+
 
+
After connecting mobile phone or other Bluetooth device and Bluetooth-4.0 module successfully (Fig 4), the LED indicator on the Bluetooth module will be steady on (stop blinking). Otherwise, the LED indicator will keep blinking. <br>
+
Now you can send commands. Send a character A to the Bluetooth-4.0 module. If the communication works normally, on the surface you can see A sent out and Rebecca returned. Then the LED on the SunFounder UNO board will blink once.<br>

====Communication====
+
If you want to  receive date sent from the arduino to your phone, and also receive data from your phone to your arduino. you should upload the follow code first,then open the IDE serial monitor and  Android app '''BleSerialPort''',now you can send the data to each other.

Introduction

Bluetooth 4.0 HM-10 Master Slave Module use TI CC2541, Master and slave roles in one, transmission version and remote control version and PIO state acquisition functions in one, Support the AT command modify module parameters, Convenient and flexible.
Transmission version can be used to transmit data between two Bluetooth devices.
Remote Control version can be used to Control PIO ports output high or low level without any other MCU.
PIO state acquisition version can be used to acquisition PIO ports state without any other MUC. (Only support Bluetooth V2.1)

Using SunFounder Uno

Step 1: Compile and upload the code before building the circuit </pre>/****************************************/

  1. include <SoftwareSerial.h>

SoftwareSerial mySerial(7, 8); // RX, TX // Connect HM10 Arduino Uno // TXD Pin 7 // RXD Pin 8

void setup() {

 Serial.begin(9600);
 // If the baudrate of the HM-10 module has been updated,
 // you may need to change 9600 by another value
 // Once you have found the correct baudrate,
 // you can update it using AT+BAUDx command 
 // e.g. AT+BAUD0 for 9600 bauds
 mySerial.begin(9600);

}

void loop() {

 char c;
 if (Serial.available()) {
   c = Serial.read();
   mySerial.print(c);
 }
 if (mySerial.available()) {
   c = mySerial.read();
   Serial.print(c);    
 }

} /****************************************/</pre>


Step 2: Connect the circuit:

Using Android

If you are using an Android phone, please follow the steps below:
Step 3: You need to download a Bluetooth 4.0 debugging assistant onto the mobile phone to connect it with the Bluetooth 4.0 module. We've provided the tool in Android. Just download BleSerialPort.zip on your smart phone and decompress. Then you can see a file BleSerialPort. Enable Bluetooth on your phone and install it.

Bt04.png

Open the installed app, as shown in Fig 1. On first use, there will be a prompt reminding you to enable the Bluetooth. Since this is a necessary step and no more prompt will appear in later use, you're recommended to enable it now in case of missing it.
Tap the vertical ellipsis button at the top right corner. Then tap connect (Fig 2). Find HMSoft and hit.

Bt05.png

After connecting a mobile phone or other Bluetooth devices and the Bluetooth module successfully (Fig 4), the LED indicator on the module will be steadily on. Otherwise, the LED indicator will keep blinking.
Tap serial monitor in Arduino IDE, and type in Hello!, then you will receive it in the mobile phone. Similarly, SunFounder send by the phone will appear in the serial monitor.

Bt06.png

Use iOS

If you are using an iPhone or MacBook, please follow the steps below (iPhone as an example):
Step 3: Go to the App store, search for the application - LightBlue and install.
Step 4: Click/Hit Settings -> Bluetooth, enable the Bluetooth and then open the LightBlue.

Bt07.png

Step 5: If the Bluetooth is connected successfully, you will see HMSoft as shown in Fig 5. Click HMSoft to connect, then it redirects to the interface in Fig 6. Now, let’s send data. Click www.jnhuamao.cn then it redirects to the interface in (Fig 7). Maybe yours is not www.jnhuamao.cn but 0xFFE1 instead, and they're the same thing in fact. Click Hex in the top right corner to set the character type.

Bt08.png

Step 6: Among the types (Fig 8), choose UTF-8 String. Hit Listen for notifications to read the value, then Write new Value to send data to Arduino as shown in Fig 9.

Bt09.png

Step 7: Click the Serial Monitor icon in Arduino IDE, and type in "Hello!". Then you will receive it in the mobile phone. Similarly, the characters "SunFounder" sent by the phone will appear in the window.

Mega2560 Code

Here the wiring is changed:

Bt11.png

//Bluetooth Module    MEGA2560
  RXD                 TXD1(pin18)
  TXD                  RXD1(pin19)
  VCC                 5V
  GND                 GND
  
void setup() {
  //define 2 serial port
  Serial.begin(9600);
  Serial1.begin(9600); 

}

void loop() {
  char c;
  //the IDE send,phone receive
  if (Serial.available()) {
    c = Serial.read();
     Serial1.print(c);
  }
  //the phone send ,IDE receive
  if (Serial1.available()) {
    c = Serial1.read();
    Serial.print(c);
  }
}

Using AT Commands

Step 1: Wiring
Connect TXD of the Bluetooth 4.0 Module to RXD of the FTDI Module, RXD to TXD, GND to GND, and VCC to VCC. The FTDI Module is a USB-to-serial bridge controller.

Bt12.png

Bt13.png

Step 2: Set parameters
After wiring, open the serial port debug tool sscom32. Set parameters at first.
1) Open the serial port, click Open Com. Select the correct port, as shown below.

COM0321.png

2) Select the correct baud rate. Here select 9600 bps (default), as shown below.
Note: You need to tick SendNew to lock it as shown below, otherwise the command cannot be sent successfully.

Bt15.png

Step 3: Now, you can start to send commands. Type in “AT” in the text box. If the Bluetooth 4.0 Module goes well, OK will be sent, as shown below:

AT.png

Also you can send AT+NAME?, then OK+NAME: HMSoft will be returned.

Name.png

Send AT+BAUD?, then OK+Get: 0 will be returned. Default: 0 (9600)
