    Here's the order of things.
    I turn on the Pixl.js badge (with the switch on the Pixl.js badge)
    The Pixl.js front red lights quickly blink.
    The ESP01S BLUE light blinks around the same time and pauses for about a second.
    Then the ESP01S BLUE light blink several times (I would say trying to connect) then suddenly STOP.
