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 ?

Can you try using the nRF Connect app to debug it?

On the Pi I know you may have to issue a few commands to wrestle that level of control off of the OS. See the steps here: https://github.com/espruino/EspruinoHub#http-proxy

@Gordon I tried nRF Connect - the name is ok. no service UUID on both platforms. dont know why Espruino doesnt see that advertisment (maybe there are other flags not visible in nRF Connect)

Try NRF.findDevices(print) just in case - it'll list all the devices that Puck.js has found
