could not run server on Linux

[SoGoDev]

I have such code , and when i check if server is running, it always return false.

import * as btSerial from "bluetooth-serial-port";

export default class Bluetooth {
  private bl;
  CHANNEL = 10; // My service channel. Defaults to 1 if omitted.
  UUID = '38e851bc-7144-44b4-9cd8-80549c6f2912'; // My own service UUID. Defaults to '1101' if omitted
  constructor() {
    this.onData = this.onData.bind(this);
    this.onError = this.onError.bind(this);
    this.onSuccess = this.onSuccess.bind(this);

    this.bl = new btSerial.BluetoothSerialPortServer();

    this.bl.listen(this.onSuccess, this.onError);
    this.bl.on('data', this.onData, {channel: this.CHANNEL})


  }

  onSuccess(address) {
    console.log('Client: ' + address + ' connected!');
  }

  onError(error) {
    console.error("Something wrong happened!:" + error);
  }

  onData(buffer){
    console.log('Received data from client: ' + buffer);
  }

}

same for me, raspberryPI, it must be a bluetooth config issue...

it may have a link with #202 (comment), or not

running sudo node [your server file name].js registers it as a "RFCOMM custom service" but no luck, can't connect to it

Tried with https://github.com/dinohorvat/pybluez--rfcomm-server

sudo python rfcomm-server.py 
Waiting for connection on RFCOMM channel 1

sudo sdptool browse local can see it, but can't connect from android bluetooth serial
