I am following a sample demo from J5 (http://johnny-five.io/examples/gps/) where they use an arduino to communicate with the Adafruit module. In my case, I am using a Beaglebone black and I adapt this code with the official dependency called beaglebone-io (https://www.npmjs.com/package/beaglebone-io).

But i got this error:

I navigated through the dependencies files found on github and i couln't found any clue.

Any ideas ?

Here is my code:

const { Board, GPS } = require("johnny-five");
const BeagleBone = require('beaglebone-io');

const board = new Board({
        io: new BeagleBone()
});

board.on("ready", () => {

  /*
   * This is the simplest initialization
   * We assume SW_SERIAL0 for the port
   */

  var gps = new GPS({
        pins: { rx: 'P9_26', tx: 'P9_24' }
  });

  // If latitude, longitude change log it
   gps.on("change", position => {
    const {altitude, latitude, longitude} = position;
    console.log("GPS Position:");
    console.log("  latitude   : ", position.latitude);
    console.log("  longitude  : ", position.longitude);
    console.log("  altitude   : ", position.altitude);
    console.log("--------------------------------------");
  });

  // If speed, course change log it
  gps.on("navigation", velocity => {
    const {course, speed} = velocity;
    console.log("GPS Navigation:");
    console.log("  course  : ", course);
    console.log("  speed   : ", speed);
    console.log("--------------------------------------");
  });

});
