Problem trying to make it work.

[danielfilho]

I've been struggling for a couple hours trying to find out what could be this error, but I just can't.

I've uploaded the firmata from Jacob Rosenthal, uploaded (it gave me an error, but on LightBlue Bean some ppl say it's ok). It appears linked on my Loader (see Sketch:firmata):

Then, I'm trying to run the "hello world" with the following code:

var beanio = require("bean-io");
var board = new beanio.Board({
  timeout: 30000 //optional - defaults to 30 seconds
  // uuid: 'myUuid' //optional - will use first bean found
});

board.on("ready", function() {
  console.log("CONNECTED");
  this.pinMode(13, this.MODES.OUTPUT);

  var byte = 0;

  // This will "blink" the on board led
  setInterval(function() {
    this.digitalWrite(13, (byte ^= 1));
  }.bind(this), 500);
});

but it gives me the following:

I've npm install --save-dev johnny-five bean-io it. any idea?

ps: I've installed johnny-five, although I'm not using it yet. I want to run the basic to go through it later.

thanks for the feedback.
There's some fixes upstream in the works now that should make this better. ble-bean and noble have been updated, and bean-serial is being worked on. Will get a new version out ASAP

[danielfilho]

thank you so much for the feedback, I'll be waiting for that and keep my eyes on, to help whenever I can (and my skills allow me to).

👍

Turns out there's been some changes in the most recent firmware. Older versions should still work, but the latest introduced a change to how serial data is transmitted: https://github.com/PunchThrough/bean-documentation/blob/master/serial_message_protocol.md

Should have some time this week to work on it.

[danielfilho]

awesome you've already mapped a possible cause for that problem. will keep my eyes on here :)

thanks for sharing.

[monteslu]

give version bean-io version 0.2.0 a spin

[danielfilho]

oh, I'm in US now and without my gadgets. in a couple weeks I'll give it a try.

thanks so far :)
