  Thanks a lot for your answers @allObjects and @Gordon !
  I have Puck.js v2, so I think the on-board FET will be a great solution for me.
  Thank you!

  Hi Everybody,
  we have 4 connection points on the bottom right part of Puck: D1, D2, 3V, GND.
  Is it possible to switch off this 3V/GND from software?
  Many thanks for the answer!

  I just found: if I re-insert the batteries after the 4) step above (without re-loading the codes), then everything work correctly. So I think it's not a problem anymore.
  Thanks!

  I tried now also the 2nd example ( at "Making it faster" ):
  Here I have the following problem:
  1) I press the button on master-puck, the green LED lights; now the red LED lights also on the slave-puck(this is OK);
  2) if I press the master-puck again, the red LED is OFF on slave-puck (this is OK also);
  3) I play this 3 times (on and off)
  4) After the 7. button press on master-puck, the green LED is always lights on master-puck, but the slave-puck do nothing. Only if I make a reset() and a new load/code copie to the master can I run this procedure again.
  5) .. and I cannot connect anymore to my slave-puck via WEB IDE, I must remove/put in again the battery

  What could be the problem here?

  Thank you Gordon, it's working now!
  I think the require("ble_simple_uart")" on WEB IDE via "Send to Espruino" was not correctly executed - it runs now fine.

  oh, sorry, my copy/paste was wrong here :-(
  here is the test what I made, and I have the problem in this version:

  //======================================­========================================­========================================­=====================
  Slave:
  
  var on = 0;
  function toggle() {
    on = !on;
    digitalWrite(LED, on);
  }
  
  --> save();
  
  //======================================­========================================­========================================­=====================
  Master:
  
  // Are we busy?
  var busy = false;
  
  // Function to call 'toggle' on the other Puck
  function sendToggle() {
    if (!busy) {
      busy = true;
      digitalPulse(LED3, 1, 500); // light blue to show we're working
      NRF.requestDevice({ filters: [{ name: 'Puck.js ae23' }] }).then(function(device) {
        require("ble_simple_uart").write(device,­ "toggle()\n", function() {
          digitalPulse(LED2, 1, 500); // light green to show it worked
          busy = false;
        });
      }).catch(function() {
        digitalPulse(LED1, 1, 500); // light red if we had a problem
        busy = false;
      });
    }
  }
  
  // Call sendToggle when the button is pressed
  setWatch(sendToggle, BTN, { edge:"rising", debounce:50, repeat: true });
  
  --> save();

  I have the pucks named "c123" (master), and "ae23" (slave).
  I followed the description at https://www.espruino.com/Puck.js+Control­ling+Other+Pucks
  1) slave: code copied to puck named "ae23" and save()
  2) master: puck name changed to "...filters: [{ name: 'Puck.js c123'..." , code copied and save()

  Testing with and without loading "require("ble_simple_uart")" on WEB IDE via "Send to Espruino"

  The result is always
  a) master: the blue LED is on (OK), then the red LED is on (KO)
  b) slave does nothing

  What do I do wrong?
  Thanks for the answer!
