Able to connect and set up Wifi using:

screen /dev/tty.wchusbserial1460 115200

as well as "nc" over Wifi:

nc 192.168.0.19 23

However, on a Mac Mojave Chrome, the serial connection does not show (baud rate changed to 115200):

Also can't connect via Wifi.

Is there a Chrome setting I'm missing?

I won't mind pasting code using "screen" however I don't know how to include "require"d modules if not already included.

I did just stick the IR pins without soldering!

Just curious how I could look into the size of the interrupt buffer? What would be the function call?

Thanks.

The example comes from here: http://www.espruino.com/Puck.js+Infrared.

Here's the output of process.memory() before and after loading the code.

process.env follows.

It is possible that the IR signals are not properly formulated i.e. more than a few transitions.
But I doubt the stream of data would overflow d[].

While running the following (example) code to read IR signals

digitalWrite(D2,0);
pinMode(D1,"input_pullup");
var d = [];
setWatch(function(e) {
   d.push(1000*(e.time-e.lastTime));
}, D1, {edge:"both",repeat:true});


var lastLen = 0;
setInterval(function() {
  if (d.length && d.length==lastLen) {
    d.shift(); // remove first element
    console.log(d.map(a=>a.toFixed(1)).toString());
    d=[];
  }
  lastLen = d.length;
},200);

I get this after a few reads:

What seems to be the issue?

How do I go about to debug this?

Thanks!
