PUCK Ble HID keyboard

OK, thanks Wilberforce. That clears up that part for me, I had tried using setTimeout (see below) as I though it may be a timing issue, it was not successful, but now I understand a little more.

function myCommand2() {
  setTimeout(sendLowA, 200);
  setTimeout(sendLowB, 200);
  setTimeout(sendLowC, 200);
}

Now I just need to figure out how to send more characters across.
