What is Arduino®

Arduino®is an open-source prototyping platform based on easy-to-use hardware and

software. Arduino®boards are able to read inputs –light-on sensor, a finger on a button or a

Twitter message –and turn it into an output –activating of a motor, turning on an LED,

publishing something online. You can tell your board what to do by sending a set of

instructions to the microcontroller on the board. To do so, you use the Arduino

programming language (based on Wiring) and the Arduino®software IDE (based on

Processing). Additional shields/modules/components are required for reading a twitter

message or publishing online. Surf to www.arduino.cc for more information.

Product Overview

The WPSH338 uses an HM-10 module with Texas Instruments®CC2541 Bluetooth v4.0 BLE

chip, fully compatible with WPB100 UNO. This shield has extended all the digital and

analogue pins out into 3PIN, making it easy to connect to sensors using 3PIN wire.

A switch is provided to switch on/off the HM-10 BLE 4.0 module, and 2 jumpers allow to

select D0 and D1 or D2 and D3 as serial communication port.

Example

In this example, we use one WPSH338 mounted on the WPB100 (UNO) and a recent Android

Smartphone to communicate with.

Please be aware that BLE (Bluetooth®Low Energy) is NOT backward compatible with the

older “Classic” Bluetooth®. For more information, please see

https://en.wikipedia.org/wiki/Bluetooth_Low_Energy.

Carefully mount the WPSH338 onto the WPB100 (UNO), copy-paste the code below into the

Arduino®IDE (or download the VMA338_test.zip file from our website).

int val;

int ledpin=13;

void setup()

{

Serial.begin(9600);

pinMode(ledpin,OUTPUT);

} void loop()

{ val=Serial.read();

if(val=='a')

{

digitalWrite(ledpin,HIGH);

delay(250);

digitalWrite(ledpin,LOW);

delay(250);

Serial.println("Velleman VMA338 Bluetooth 4.0 Shield");

}

Remove the two RX/TX jumpers from the WPSH338 or switch off the HM-10 module (you

have to send the code to the WPB100, not to the WPSH338), and compile–upload the code.

Once the upload finished, you can put back the two jumpers or switch on the HM-10.

Now, it is time to prepare the smartphone where we need a Bluetooth®terminal to talk and

listen to the WPSH338. As mentioned before, BLE 4.0 is NOT compatible with classic

Bluetooth®so many of the available Bluetooth®terminal apps will NOT work.

Download the app BleSerialPort.zip or BleSerialPort.apk from our website.

Install the BleSerialPort app and open it.

You will see a screen like this. Tap on the three dots and select “connect”.

Make sure the Bluetooth®function is switched on and your phone is BLE compatible. You

should now see the WPSH338 under the name HMSoft. Connect to it.

Type “a” and send it to the WPSH338. The WPSH338 will answer with “Velleman WPSH338

[…]“.

At the same time, the LED connected to D13 on the WPB100 (UNO) will switch on for a few

seconds.
