NRF.setScan doesn't show advertisment packets sent from Raspberry Pi

I am trying to send an advertisment packet from a raspberry pi zero w using nodejs with bleno:

var bleno = require('bleno')
var name = 'tbd-pager-pi';

console.log('bleno server start')

bleno.on('stateChange', function(state) {
 console.log('on -> stateChange: ' + state);
 if (state === 'poweredOn') {
     bleno.startAdvertising(name, []);
 } else {
     bleno.stopAdvertising();
   }
});

tested with nRF Connect/iOS and the advertisment is visible and connectable with Complete Local name set correctly

on a Puck.JS I am using this code:

NRF.setScan(function(e){
  if(e.name && e.name.indexOf('tbd-pager') > -1){
    digitalPulse(LED3, 1, 100);
  }
});

setWatch(function () {
  print("scan disabled");
  digitalPulse(LED1,1,100);
  NRF.setScan();
}, BTN1, { repeat:true, debounce:true, edge:'rising' });

the problem is that there no found message and no LED3 blinking :(

same code that runs on Raspberry moved to OSX works perfectly

any idea why I cannot see the advertisment from Raspberry ?
