PuckJS Infrared - Does the case get in the way?

Your first line (D25,D26) produces result but not (D26,D26)!

var cmds = {

I guess I will use D25,26 for transmission.

A query: not sure why the first value is consistently missing (i.e. 9.0).

Am I in fact transmitting the inverse pattern or am I just not understanding the IR protocol? (The definition file was captured (transmitted from a physical remote) using the same Receiver code, i.e. (from you!)

function onInit() {

	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);

	setInterval(() => LED3.toggle(), 500);
