Empty Data

[cfontana0]

Hey folks!
I'm trying to use the HCE feature on Android to transmit data from the phone to an ACR122 reader.
I was able to read the sent information from the Android phone with another phone, so, that means that it's transmitting correctly.
However, when I try to read the information using the ACR122 reader, I receive this as data:

New reader detected ACS ACR122U
Status( ACS ACR122U ): { state: 18, atr: <Buffer > }
card removed
Disconnected
Status( ACS ACR122U ): { state: 34, atr: <Buffer 3b 80 80 01 01> }
card inserted
Protocol( ACS ACR122U ): 2
Status( ACS ACR122U ): { state: 290, atr: <Buffer 3b 80 80 01 01> }
Data received <Buffer 69 86>

Any idea?

I'm running the following code:

const pcsclite = require('@pokusew/pcsclite');

const pcsc = pcsclite();

pcsc.on('reader', (reader) => {

    console.log('New reader detected', reader.name);

    reader.on('error', err => {
        console.log('Error(', reader.name, '):', err.message);
    });

    reader.on('status', (status) => {

        console.log('Status(', reader.name, '):', status);

        // check what has changed
        const changes = reader.state ^ status.state;

        if (!changes) {
            return;
        }

        if ((changes & reader.SCARD_STATE_EMPTY) && (status.state & reader.SCARD_STATE_EMPTY)) {

            console.log("card removed");

            reader.disconnect(reader.SCARD_LEAVE_CARD, err => {

                if (err) {
                    console.log(err);
                    return;
                }

                console.log('Disconnected');

            });

        }
        else if ((changes & reader.SCARD_STATE_PRESENT) && (status.state & reader.SCARD_STATE_PRESENT)) {

            console.log("card inserted");

            reader.connect({ share_mode: reader.SCARD_SHARE_SHARED }, (err, protocol) => {

                if (err) {
                    console.log(err);
                    return;
                }

                console.log('Protocol(', reader.name, '):', protocol);

                reader.transmit(Buffer.from([0x00, 0xB0, 0x00, 0x00, 0x20]), 40, protocol, (err, data) => {

                    if (err) {
                        console.log(err);
                        return;
                    }

                    console.log('Data received', data);
                    reader.close();
                    pcsc.close();

                });

            });

        }

    });

    reader.on('end', () => {
        console.log('Reader', reader.name, 'removed');
    });

});

pcsc.on('error', err => {
    console.log('PCSC error', err.message);
});

I also tried this library: https://github.com/pokusew/nfc-pcsc, but it requires defining an AID, should I do the same here?

Thanks,
