Example Code for Arduino-Check Button A Press

Hardware Preparation

• BLUNO (An Arduino Bluetooth 4.0 (BLE) Board/Bluno Nano/BLE link x1
• BLE Wireless Gamepad x1

Software Preparation

• Download Arduino IDE: Click to download Arduino IDE
• BLE Wireless Gamepad library (Gitbub)

Other Preparation Work

Set the receiver end to peripheral mode, turn on the gamepad and put both less than 10 cm to establish Kiss connection.

Sample Code

int str[14]={'\0'};
void setup()
{
    Serial.begin(57600);
}

void loop()
{
    if(Serial.available())
    {
        for(int i=0;i<14;++i)
        {
            str[i] = Serial.read();
            delay(2);
        }
        if(str[6] & 0x01)
        {
            //Press button A
        }
    }
}

Result

When button "A" is pressed, the condition str[6] & 0x01 becomes true, and the code inside the conditional block (commented as "Press button A") executes.
