i was desingning an app that can communicate between android phone and arduino board. but whenever i connect the android device to the arduino the USB is detected and working but it says No arduino board detected. Below is the detection code, I really need help and any help from you will be highly appreciated.
C-like:
private void detectConnectedArduinoBoard() {
if (usbManager == null) {
Toast.makeText(this, "USB manager is not available", Toast.LENGTH_SHORT).show();
return;
}
HashMap<String, UsbDevice> deviceList = usbManager.getDeviceList();
if (deviceList.isEmpty()) {
Toast.makeText(this, "No USB devices detected", Toast.LENGTH_SHORT).show();
return;
}
for (Map.Entry<String, UsbDevice> entry : deviceList.entrySet()) {
UsbDevice device = entry.getValue();
if (isArduinoUnoDevice(device)) {
// Display Arduino Uno board info
String info = "Arduino Uno board detected\nManufacturer: " + device.getManufacturerName() +
"\nProduct Name: " + device.getProductName() +
"\nVendor ID: " + device.getVendorId() +
"\nProduct ID: " + device.getProductId();
Toast.makeText(this, info, Toast.LENGTH_LONG).show();
return;
} else if (isArduinoNanoDevice(device)) {
// Display Arduino Nano board info
String info = "Arduino Nano board detected\nManufacturer: " + device.getManufacturerName() +
"\nProduct Name: " + device.getProductName() +
"\nVendor ID: " + device.getVendorId() +
"\nProduct ID: " + device.getProductId();
Toast.makeText(this, info, Toast.LENGTH_LONG).show();
return;
} else if (isUSB2SerialDevice(device)) {
// Display USB2.0 Serial device info
String info = "USB2.0 Serial device detected\nManufacturer: " + device.getManufacturerName() +
"\nProduct Name: " + device.getProductName() +
"\nVendor ID: " + device.getVendorId() +
"\nProduct ID: " + device.getProductId();
Toast.makeText(this, info, Toast.LENGTH_LONG).show();
return;
}
}
Toast.makeText(this, "No Arduino board detected", Toast.LENGTH_SHORT).show();
}
// Method to check if the connected device is an Arduino Uno
private boolean isArduinoUnoDevice(UsbDevice device) {
// Replace these vendor and product ID values with the actual IDs of the Arduino Uno
return device.getVendorId() == 9025 && device.getProductId() == 67;
}
// Method to check if the connected device is an Arduino Nano
private boolean isArduinoNanoDevice(UsbDevice device) {
// Replace these vendor and product ID values with the actual IDs of the Arduino Nano
// Example IDs for Arduino Nano
return device.getVendorId() == 1027 && device.getProductId() == 24577;
}
// Method to check if the connected device is a USB2.0 Serial device
private boolean isUSB2SerialDevice(UsbDevice device) {
// Replace these vendor and product ID values with the actual IDs of your USB2.0 Serial device
// Example IDs for USB2.0 Serial
return device.getVendorId() == 1234 && device.getProductId() == 5678;
}
// Register BroadcastReceiver for USB device attachment and detachment events
// Register BroadcastReceiver for USB device attachment and detachment events
private void registerUSBReceiver() {
usbReceiver = new BroadcastReceiver() {
[USER=54416]@override[/USER]
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (UsbManager.ACTION_USB_DEVICE_ATTACHED.equals(action)) {
// USB device attached, trigger detection
detectConnectedArduinoBoard();
} // USB device detached, no action needed in this case
// Device detachment might not require any action in this context
}
};
IntentFilter filter = new IntentFilter();
filter.addAction(UsbManager.ACTION_USB_DEVICE_ATTACHED);
filter.addAction(UsbManager.ACTION_USB_DEVICE_DETACHED);
registerReceiver(usbReceiver, filter);
}
// Unregister the USB BroadcastReceiver
private void unregisterUSBReceiver() {
if (usbReceiver != null) {
unregisterReceiver(usbReceiver);
}
}
}
