PuckJS and Espruino Hub and MQTT bridge

Did some test with two pucks, Puck.js f5b9 and Puck.js 4820, using NRF.requestDevice and try to create a AND for id and manufacturerData.

d9:c7:0b:0a:48:20 - Puck.js 4820 (RSSI -59)
f0:d8:ef:29:f5:b9 - Puck.js f5b9 (RSSI -58)

// advertise code for both Puck.js
function onInit(){
      var data = {a:"1",b:2};
      NRF.setAdvertising({},{
            showName:true,
            manufacturer:0x0590,
            manufacturerData:JSON.stringify(data)
      });
}
setTimeout(save,1E3);

Then run this simple code

// manufacturerData and name as AND?
filter = [{manufacturerData:{0x0590:{}}},{name:"Puck.js 4820"}];

// some times this 
>NRF.requestDevice({ filters: filter}).then(function(d){console.log(d);});
=Promise: {  }
BluetoothDevice: {
  "id": "f0:d8:ef:29:f5:b9 random",   <-- wrong device
  "rssi": -61,
  "data": new Uint8Array([2, 1, 6, 18, 255, 144, 5, 123, 34, 97, 34, 58, 34, 49, 34, 44, 34, 98, 34, 58, 50, 125, 8, 8, 80, 117, 99, 107, 46, 106, 115]).buffer,
  "manufacturer": 1424,
  "manufacturerData": new Uint8Array([123, 34, 97, 34, 58, 34, 49, 34, 44, 34, 98, 34, 58, 50, 125]).buffer,
  "shortName": "Puck.js"
 }

// and some times that
>NRF.requestDevice({ filters: filter}).then(function(d){console.log(d);});
=Promise: {  }
BluetoothDevice: {
  "id": "d9:c7:0b:0a:48:20 random",   <-- correct device
  "rssi": -44,
  "data": new Uint8Array([2, 1, 6, 18, 255, 144, 5, 123, 34, 97, 34, 58, 34, 49, 34, 44, 34, 98, 34, 58, 50, 125, 8, 8, 80, 117, 99, 107, 46, 106, 115]).buffer,
  "manufacturer": 1424,
  "manufacturerData": new Uint8Array([123, 34, 97, 34, 58, 34, 49, 34, 44, 34, 98, 34, 58, 50, 125]).buffer,
  "shortName": "Puck.js"
 }

Try different filter possibility

// manufacturerData and name as AND ?
filter = [[{manufacturerData:{0x0590:{}}}],[{name:"Puck.js 4820"}]];

// some times this
>NRF.requestDevice({ filters: filter}).then(function(d){console.log(d);});
=Promise: {  }
BluetoothDevice: {
  "id": "d9:c7:0b:0a:48:20 random",

  "data": new Uint8Array([2, 1, 6, 18, 255, 144, 5, 123, 34, 97, 34, 58, 34, 49, 34, 44, 34, 98, 34, 58, 50, 125, 8, 8, 80, 117, 99, 107, 46, 106, 115]).buffer,
  "manufacturer": 1424,
  "manufacturerData": new Uint8Array([123, 34, 97, 34, 58, 34, 49, 34, 44, 34, 98, 34, 58, 50, 125]).buffer,
  "shortName": "Puck.js"
 }

// or sometimes this
>NRF.requestDevice({ filters: filter}).then(function(d){console.log(d);});
=Promise: {  }
BluetoothDevice: {
  "id": "de:30:d5:92:80:7f random",
  "rssi": -54,
  "data": new Uint8Array([2, 1, 6, 13, 9, 77, 68, 66, 84, 52, 50, 81, 32, 56, 48, 55, 102]).buffer,
  "name": "MDBT42Q 807f"
 }
// or sometimes this 
>NRF.requestDevice({ filters: filter}).then(function(d){console.log(d);});
=Promise: {  }
BluetoothDevice: {
  "id": "f0:d8:ef:29:f5:b9 random",
  "rssi": -60,

Hmm, not sure about filters any more.....
