PuckJS and Espruino Hub and MQTT bridge

Use a Puck to advertise data and try to read them via MQTT client, but data is not visible via mqtt client.

Configuration and snipped to advertise taken from the the Espruino Hub repo page

Device: d9:c7:0b:0a:48:20 - Puck.js 4820 (RSSI -59)

snippet on for Puck.js 4820

function onInit(){
      var data = {a:"1",b:2};
      NRF.setAdvertising({},{
            showName:false,
            manufacturer:0x0590,
            manufacturerData:JSON.stringify(data)
      });
}

setTimeout(save,1E3);

Advertising is visible on Espruino Hub and BluefruitConnect.

Connect to the mqtt server and subscribe to /ble/advertise/d9:c7:0b:0a:48:20/espruin­o and /ble/advertise/d9:c7:0b:0a:48:20/#. Get many payloads for the second sub but none for the first.

Any hints what's missing?
