Status of the "Android Integration" app

This is great news, thanks Gordon for the work in Gadgetbridge!
I already played with the ble-gateway on a esp32 for a smarthome-control-app but always had problems with coverage in my house. Over the phone should be much more reliable.

So I tried via Intents and an Android-App called "Broadcast to MQTT" but I only get one out of 10 messages arriving in this app. My watch is in 10-20 cm distance to my phone.

Can anyone guess what could be the problem?

Or is BLE in general as unreliable as I'm experiencing, so I would have to build a repeat-function on the bangle and then merge duplicates together on nodered? Or is there a possibility for a Callback (seems like global.GB = (event) => .. is currently not called with intents) to verify that gadgetbridge has recieved the message.

Below my test-code for my bangle2 :

var Layout = require("Layout");
var layout = new Layout( {
  type:"v", c: [
    {type:"txt", font:"6x8:2", label:"A Test", id:"label" }
  ]
}, {btns:[
  {label:"One", cb: l=>httpCall("One"),  cbl: l=>httpCall("One long press")}
], lazy:true});

g.clear();
layout.render();

var counter=0;


function httpCall(){     Bluetooth.println(JSON.stringify({t:"int­ent",action:"com.sonyericsson.alarm.ALAR­M_ALERT",extra:{key1:"asdfas",}}));
counter++;
setLabel(counter);
}

function setLabel(x) {
  layout.label.label = x;
  layout.render();
}

global.GB = (event) => {
   if(event.t == "intent"){
      if(event.err)
        E.showAlert(event.err);
      else
        E.showMessage(event.resp +"from MQTT");
   }else{
     E.showAlert("Event was: "+event.t);
   }
};
