Our app uses Expo push notification to deliver push messages. It works just fine for most clients, but I am trying to debug one client where he is not receiving the push messages. Here is what I am seeing:
Using Expo push notification tool as well as my own client code, I
can send messages to his Expo push token. Expo server responds with
ok status. I checked the status given the receipt id and the status
also says ok.
But the client never receives the messages. I ensure
that the app is not already opened on his iOS device and that
notification is enabled for the app.
My question is: how do I debug this further? I understand that Apple server might decide to send or not to send messages based on various factors. How do I find out what Apple server did with the messages?
I have googled quite a bit but I couldn’t find much info on how to proceed. I hope that someone has experienced the same, and can help with some leads.
Thanks for your help,
Huey

I have setup WSo2 EMM correctly. Noticed that device information and Get All Applications Notifications go pending and are never delivered to the devices. The status of these notifications in the database table is also P.
The only way to deliver these messages are by pushing the Camera Enable/Disable Operation or some other notifications, then the older pending notifications get delivered.
Seems they are stuck. This also happens to policy enforcement notifications. I have to manually push camera disable/enable to make these works.
Why does this happen? The notifications should be delivered instantly, like they do in Camera Enable/Disable case.
I am connected in Production Mode. Any pointers to sort this out?
I was using Java 1.6 earlier. Once I switched the JDK to 1.7, it appears to so far work well.
I am developing chat application using XMPP protocol.
My development target is iOS 7.0
Every think is working fine user can able to communicate only when they are online.
But I want to notify user message has come when they are offline.
I have tried iphone XMPP App run background
But it doesn’t work for me.
First think it is possible or not?
Using what VIOP, background fetch or some other way?
If yes please let me know. how?.
The thread you are referring mention declaring that your app is a VoIP app to be allowed to constantly run in background.
It is technically possible but has two drawbacks:
If your application does not do voip, Apple will reject it (as misleading).
Battery consumption will be excessive as you will stay connected.
The state of the art is to fallback to Apple push notification service when the TCP connection between the client and the server is not established. This is battery efficient and provide a very good way to notify the user of new messages.
My question is as follows:
I have a database on another server with the appropriate records of the devices.
I can send a notification by REST API without necessarily making an installation registry?
Something like:
"Send notification to the following devices:
- id1
- id2
- Id3 "
My idea is to continue to use my other server without getting spending requests or hosting Parse. Only use the push notifications service.
Is it possible?
Not sure what types of devices you are referring to (iOS? Android? Windows Phone?), but push notifications to mobile devices always require an application to be installed on the target device, since the notification is sent to a specific application on a specific device.
And the only way you can get a device ID (which you can use to send push notification to a device) is by having an application on the device send that ID to your server after obtaining it from the relevant push notifications service (APNS for iOS, GCM for Android, etc...).
I'm using Worklight 6.1 on Liberty profile 8.5.5 in Windows XP in a VMWare in a Mac.
I have an Android app that receives notifications. I'm using an adapter to send the notifications.
It is my own app but the adapter is the same as in the push notifications sample project provided by IBM.
For sending the notification I'm directly calling the adapter from a browser using the REST call (protocol://server:port/app/[dev/]invoke?adapter=myAdapter&procedure...)
When I execute the application in the development server the notifications arrives almost immediately, but when I test the application in the test server (mentioned above) the notifications takes a lot of time to arrive, if they arrive.
However, when the notification does arrive, the next notifications arrives in seconds.
It is something I have experienced in the past also with previous Worklight versions.
I do not know what is the difference between the servers or if the problem is related to the server.
Any hints for debugging this?
I have enabled the trace:
<logging traceSpecification="*=audit=enabled:com.worklight.integration.notification.*=finest=enabled" />
I can see the trace:
com.worklight.integration.notification.gcm.GCMSender 1 sendNoRetry Sending JSON to GCM server: {"collapse_key":"myPush","data":{"alert":"Hay una nueva ficha","payload":"{\n \"alias\": \"myPush\",\n \"identificador\": \"a035\",\n \"nombre\": \"aName35\"\n}","badge":"1"},"registration_ids":["APA91bG03cXkyVM6pA2-CO1g-tZUQL6FwJgugaa68YngIyGbbR_oDzVNn-1RULpoktvMUKwF3D1qK4bx-4OVeAbUzBqNpqO3m_1hwz0Z6I0B_DS_Jvc0wzI_fjKpJ9vqPNO58Bdt40ms"]} [project DemoM]
But I do not know if that trace means that everything has gone ok and the message is now in the GCM servers.
I have also enabled sniffers (WireShark in Mac and SmartSniff in XP) in dev server and stand alone server but I have not been able to detect any pattern. Everything is under https so I only see some traces for google hosts but I can not take any conclusions. Although it is valid to see a trace for google gcm immediately after the server trace that takes less than 500ms
Anyway now it is taking time to the notification to arrive in both servers so I guess everything is working fine in the worklight side.
I recently got the Xoom, for some reason I thought you could SMS message on it :-S
Does anyone know a way that from my android phone I can push a notification to my tablet to tell me I have a message or even if someone is calling.
Basically I want to mainly use my tablet and keep my phone in my laptop bag but be notified if I get a message.
Any help will be greatly received.
You will need to develop an application which can talk to another instance of the same application over Bluetooth (or Wi-fi). The application running on the phone can listen for the broadcast of an incoming SMS, and send the info to the paired device (Xoom) where it will throw a Notification.
If anyone is interested it seems HTC have solved this.
HTC have an online service for sense found at: https://www.htcsense.com
From here once you have linked your Google account you can read and send text messages pushing them through your phone.
This allows me to use the browser on my Xoom tablet to send SMS messages.
