Create async function within a plugin

[w-mazed]

Hi everyone,

I want to create a plugin to use the sdk of a UHF Sled Reader, in this case, in definitions.ts I've a function that I named connect it calls the function connect of ChainwayR6 class, wich use a callback device.connect(address, btStatusCallback); to connect, so the connection will be done inside getStatus function.

How can I return the connected status from that function to my Capacitor plugin.

Thanks.

// src/definitions.ts
export interface ChainwayR6Plugin {
    connect(options: { address: string }): Promise<{ success: boolean }>;
}

// android/src/main/.../ChainwayR6Plugin.java
@CapacitorPlugin(name = "ChainwayR6")
public class ChainwayR6Plugin extends Plugin {

    private ChainwayR6 implementation;

    @Override
    public void load() {
        implementation = new ChainwayR6(getContext());
    }

    @PluginMethod
    public void connect(PluginCall call) {
        String address = call.getString("address");

        JSObject ret = new JSObject();

        implementation.connect(address, null);

        ret.put("success", true);

        call.resolve(ret);

    }

// android/src/main/.../ChainwayR6.java
public class ChainwayR6 {

    private BLEStatus bleStatusCallback;

    public ChainwayR6(Context context) {
        this.device = RFIDWithUHFBLE.getInstance();

        appContext = context;

        init(appContext);
    }

    private void registerListeners() {
        bleStatusCallback = new BLEStatus();
    }

    public void connect(String address, ConnectionStatusCallback<Object> btStatusCallback) {
        if (device.getConnectStatus() != ConnectionStatus.CONNECTING) {
            if (btStatusCallback != null) device.connect(address, btStatusCallback);
            else device.connect(address);
        }
    }

    class BLEStatus implements ConnectionStatusCallback<Object> {
        private static final String TAG = "BLEStatus";

        @Override
        public void getStatus(final ConnectionStatus connectionStatus, final Object device1) {

            BluetoothDevice deviceTmp = (BluetoothDevice) device1;
            ChainwayR6Device readerDevice = ChainwayR6Device.Builder.aReaderDevice()
                .setAddress(deviceTmp.getAddress())
                .setName(deviceTmp.getName())
                .build();

            if (isConnecting()) {
                Log.v(TAG, "getStatus: device connected");
            } else if (isDisconnected()) {
                Log.d(TAG, "getStatus: disconnected, try connect more time");

                init(appContext);

                connect("EA:3A:6B:50:0E:EE", bleStatusCallback);
            } else {
                Log.v(TAG, "getStatus: connection failed");
            }
        }
    }

For those who are facing the same issue, a friend told me about EventBus, and yeah it do the work properly.
