PeerSocket.onopen seems to working only if I launch fitbit app and sync the ionic

[pachesnel]

Hi! 

I'm currently developing an application for managing my to do list and I've got some issue with the waking of the companion when I launch the app. Every time I'm wait a few hours I've the obligation to launch the fitbit app and synchronise the ionic. After that I can launch again my app and make working the communication between app and companion. It's seems not fire the peerSocket.onopen 😕 

I've similary issue with another app I've made. Thank's in advance for your help!

// Listen for the onopen event
messaging.peerSocket.onopen = function() {
  console.log('1 - messaging on open');
  // ask for the list of projects
  if (messaging.peerSocket.readyState === messaging.peerSocket.OPEN) {
    // Send the data to peer as a message
    console.log("2 - send message for waking up companion")
    messaging.peerSocket.send("getProjects")
  }
}

You should do it reversely.

The onopen event fires just once, and at the moment you are setting it, you don't know if it didn't fire already without you having a listener set on it.

So a surefire way to send the message if the socket is open is such:

function sendMessage(msg) {
	if (messaging.peerSocket.readyState === messaging.peerSocket.OPEN) {
		messaging.peerSocket.send(msg)
	} else {
		messaging.peerSocket.onopen = () => {
			messaging.peerSocket.send(msg)
		}
	}
}
