Why does this code keep sending messages without button presses?

Here is my code for the puck v2. The idea is that when the button is pressed, it sends info (the button count, the battery level and the z-axis value) to Node-Red so that Node-Red can react to the event.

    var pressCount = 0;
    var batt = 0;
    setWatch(function() {
      batt = Puck.getBatteryPercentage();
      var acc_gyro = Puck.accel();
      pressCount++;
      NRF.setAdvertising({
        0x1812 : [pressCount],
        0x180f : batt,
        0x1821 : acc_gyro.gyro.z
      });
    }, BTN, { edge:"rising", repeat:true, debounce:50 });

So, kind of works, but then it keeps sending

Here is the first batch of three data points (button count, power and z-axis):

Am I missing something with this? I thought the puck would sleep until the next press.

On a side note... it seems like there are RSSI messages very frequently. Do they use just a small bit of power?
