  I am likely wrong here - but I'm trying to NOT use the full BLE stack. i.e. I'm looking to have two microbits communicate with each other, without having to pair them.

  I tried your suggestion - but it didn't work - I think this is because I'm looking to have two microbits communicating without a 'central' PC.

  Am I barking up the wrong tree - or is this something Espruino can do - i.e. radio comms without pairing.

  I do have this working in uPython now - but I would prefer to use Espruino - if possible.

  Best wishes

  Hello Everyone
  Gordon has already kindly pointed me in the direction of more documentation. Unfortunately, I'm not an Espruino person - so I'm missing a lot of the background knowledge - so the Espruino radio api doesn't mean anything to me.

  Does anyone whether it is possible, or how, to access the radio from Espruino. As a example, I have a simple javascript (written for the blockly...microsoft editor) that follows:
  N.B. I know this won't work in Espruino...

  let x = 0
  let y = 0
  input.onButtonPressed(Button.B, () => {
      radio.sendNumber(x + 5 * y)
  })
  input.onButtonPressed(Button.A, () => {
      led.unplot(x, y)
      x += 1
      if (x > 4) {
          x = 0
          y += 1
          if (y > 4) {
              y = 0
          }
      }
      led.plot(x, y)
  })
  radio.onDataPacketReceived(({receivedNumber: recd}) => {
      y = recd / 5
      x = recd - y * 5
      led.plot(x, y)
  })
  x = 0
  y = -1
  radio.setGroup(4)
  

  Any hints, tips, tutorials or pointers to documentation would be very welcome.

  Best wishes
