    This has been flashed with

    VERSION: "2v04",
      GIT_COMMIT: "3956264e",
      BOARD: "ESP8266_4MB",
      FLASH: 0, RAM: 81920,

      MODULES: "Flash,Storage,hea" ... "r,crypto,neopixel",
      EXPTR: 1073643636
    

    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):

    Handling URL "https://www.espruino.com/ide/#"

    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!
