BLE-LINK: Bluetooth 4.0 wireless programming and communicati

It is very trouble, when you debug the Arduino project. Especially the sketch uploading!
You have to plug and unplug the USB cable again and again. 
It is time to git rid of it now.

The new  DFRobot product: BLE-LINKwill help you to realize this situation.

BLE Link is a communication module based on bluetooth 4.0, it uses the XBEE model which is compact and is compatible with all shields with XBEE socket. BLE Link supports both 5V and 3.3V MCUs. 
By linking into star network of low power consumption, BLE achieves rapid real-time communication. Many software or hardware engineers are hoping to have such a platform that is able to do this.

Get down to business
What we need :
BLE-LINK module                    x2
I/O expansion shield V7        x1
Arduino board: UNO              x1

Step 1: Preparation 
We need set the role of the two modules: a Master and a Client.
What you need to pay more attention are:
1 Role :                AT +ROLE    
2 baud rate:        AT+UART
3 Connect mode:  AT+ CMODE

Step 2: Hardware connection
After you have finished the BLE setting.
It will be very easy.
Plug client on the I/O expansion shield, and plug the I/O expansion shield on the UNO.
Plug master to your PC usb port.

Step 3: Uploading 
Select your Arduino board in Arduino IDE. 
Select your USB COM port(BLE)
Click "upload"

NB: When you power two modules, the leds "LINK" will be turn on(if the parameter setting is correct.)

Receive sample code:
 

Code: Select allvoid setup()
{  
  Serial.begin(115200);
}

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

 

This module has a long transmission distance:  about 60m in free space.
And very low power consumption.
So, don't be waiting, just do it!



Update 2014/12/23 
Now it has been a new product USBBLE-LINK, it is a BLE dongle, which has the same function like BLE Link
