wire toggle value in settings to bool var in app (begginer)

[Slumberlander]

Hi there,

sorry for this one...

i m very unfamiliar with programming and totally new to fitbit sdk.

it sounds very basic but i m struggling. i simply want to wire the value of toggle btton in my settings to a var boolin my app.

in my *.jsx

<Toggle
          settingsKey="toggle"
          label="myToggle"
          />

then in my app/index.js

import * as messaging from "messaging";
import document from "document";

let myBool =new Boolean(true);

  messaging.peerSocket.onmessage = evt => {
  console.log(`App received: ${JSON.stringify(evt)}`);

      if (evt.data.key === "toggle" && evt.data.newValue)
       {
      myBool = (JSON.parse(evt.data.newValue)).name;
       console.log(`New date: ${myBool}`); 
      } 
}

that is not working, could someone show me the wright writing for this? 

thank you !

You need some code in your companion\index.js to handle when your settings page changes your settings

settingsStorage.onchange = evt => {

  var data = {}

  data[evt.key] = JSON.parse(evt.newValue)

  update(data,false)

}

You also need something to send from your companion code to your app code

export function transmit(){                        // Send data to device using Messaging API

  if (messaging.peerSocket.readyState === messaging.peerSocket.OPEN && ( Object.keys(e.dReq).length !== 0 ) ) {

    let keys=Object.keys(e.dReq)

    if(keys.length>0){

      let dReq={}

      dReq[keys[0]] = e.dReq[keys[0]]

//      lg("Tran",keys[0],function(T){console.log(T)})

      messaging.peerSocket.send({dR:dReq})

      delete e.dReq[keys[0]]

      clearTimeout(tmrTimeout)

      tmrTimeout = setTimeout(transmit, 100)

    }

  }

}
