• Hi @Gordon,

    I am looking for the spec for the IR transmitter on the PuckJS. I have been able to use your demo code to transmit and receive IR signals using a pair of PuckJS and 940nm transmitter and https://www.vishay.com/docs/82491/tsop38­2.pdf receiver using the following code to test:

    setWatch(() => {
        Puck.IR(cmds.mainSelect);  // line 1
        Puck.IR(cmds.mainSelect, D31, D30); // line 2
        LED2.toggle();
    }, BTN1, true);
    

    Line 2 works as advertised.

    When I use line 1 only, I cannot get any reading. I doubt the onboard transmitter is busted so it could be an incompatibility issue somewhere else?
