Apple Push Notification Service Not Working? Try Changing Firewall Settings

Apple Push Notification service (APNs) is a simple, efficient and high capacity transport service that is at the core of the push notifications feature. The service helps in transmitting messages or push notifications to iOS and OS X devices. These devices receive notifications over a persistent connection by establishing encrypted and accredited IP connections with the APN service.

Service-to-Device Connection

Service-to-Device Connection

Why isn’t it working for me?

If the APNs isn’t working, there could be a server or client based issue. A common problem is the device being unable to connect to Apple’s server because the device doesn’t have a cellular data account or signal despite being connected to Wi-Fi. As a direct and persistent connection is a must for APNs, the device won’t be able to use the service if the Wi-Fi network has a proxy server.

What should I do?

The address block range needs to be allowed in your firewall settings as it is assigned to Apple. Moreover, the below ports need to be opened so that APNs traffic can get past your firewall:

  • TCP port 2195; which is used to send notifications to the APNs
  • TCP port 2196; which is used by the APNs feedback service
  • TCP port 5223; which is used by iOS and OS X devices to communicate with APNs servers
  • TCP Port 443; which is used when a device is unable to communicate to the APNs on port 5223 as a fall back on Wi-Fi

Amazon’s Dash: An Amazingly Easy Way to Purchase Groceries and More!

How would you like to receive your grocery delivered right outside your doorstep without having to step out of your house? And no, you don’t have to ring up someone and give them a list of all that you need. Just scan barcodes or record what you need in your voice with Amazon’s Dash and voilà you’re done!

amazon dash

Amazon dash

Sounds too good to be true? Well, it is true! Right now, this is a reality only for residents of Seattle, Southern California and San Francisco where AmazonFresh stores are located. But don’t be disheartened because this year, AmazonFresh has plans to expand to about 20 other urban areas in and outside the US.

So what exactly is Amazon’s Dash? It’s like a magic wand with an LED barcode scanner and a microphone. It’s a hand-held device the size of a remote. When you run out of stuff, you point the Dash at the barcode on the item you need or you can order generic items such as eggs and apples by speaking into the microphone. The Dash is Wi-Fi enabled so you can pair it up with your smartphone or computer. The items you need are sourced from AmazonFresh and you can see the list of items you selected on the paired mobile or laptop. You can then progress to making payment and scheduling a delivery time as per your convenience. Now you will never run out of flour, breakfast cereal or toilet paper!

Want to get your hands on the Dash? Sadly enough, you’ll have to wait for AmazonFresh to set up stores in your locality.

Lets Nurture Embraces the iBeacon Phenomenon for Technologically Advanced Apps

At Lets Nurture, we believe in evolving along with the rest of the world. People are experimenting with iBeacon and putting this technology to use in a wide range of industries- banking, healthcare, restaurants, offices and lots more.

iBeacon uses Bluetooth Low Energy (BLE) or Bluetooth 4.0 and geofencing over a limited range. The range of the device changes according to function and varies from a radius of a few centimeters to 10 meters. The device can send messages to mobile devices and also receive messages from them via applications specially created to support this technology. Apps are made by companies and a user needs to download a company’s app on their phone in order to receive updates, notifications or offers from them.


Imagine walking into a bank and receiving a welcome message or directions to the cashier! How wonderful can it be to receive a promotional message on your smartphone for a particular product when you walk past it in a supermarket? Yes, iBeacon can do all of this and much more! Needless to say, the technology can boost business or sales.

At Lets Nurture, we are working to provide all possible benefits of this wonderful technology through special applications created by our team. Get in touch with us to know more!

Blood Monk Can Help People in More Ways Than One

Engaging in social work gives one a feeling of genuine happiness. As an IT firm, Lets Nurture put their heart and soul into creating an iPhone application that is social work all the way.

Blood Monk is the name of this wonderful application that was created with an aim to help people donate blood and receive blood in times of need. With the difficulties one faces when one needs to receive blood, it was imperative to this Ahmedabad based company to do its part for the society. Users of this application can find the names of blood donors in their city and first-hand information regarding the nearest hospital within minutes on their smartphones.

Blood Monk iOS Mobile Application |Android Mobile Application

The application has three tabs. The first is the ‘Register Blood Monk’ tab. Clicking on this tab enables users to do their bit for others by registering as a blood donor. One can register a relative for this noble deed too. The second is the ‘Search Blood Monk’ tab. Users are able to select their blood group and locality. Related users of the application having the same blood group and residing in the same area can be located by clicking on the ‘Search’ button. These donors can be called, messaged or emailed by clicking on any one of them and getting their contact details. The third tab is the ‘Monks on Map’ tab. This displays all information regarding registered donors, major hospitals and blood banks on Google Map. Users are able to filter results according to their needs.

So if you are willing to do something for others, register right away. Not everyone may be comfortable with the idea of donating blood.

An App that Provides Testing Solutions for Mobile App Developers

Technology has been changing every few days or months. New mobile solutions and applications are being used by the clients worldwide. However, there is always a need for a service to test every smart phone platform and operating system.

Information on TestFlight

This app is for the managers, testers and mobile developers to provide them a testing service solution that they can work on effectively. The app provides the testers an efficient work approach to test the iOs and Android SDK platforms.

There are some issues that the testers and developers regularly face while developing the apps. Some of the issues relate to the locating the beta testers for testing apps, manage them alongside the work and get the required feedback.  The testflight is the right app that solves these issues in a simple manner. One simply has to register into the web service and download the app from their devices. This app can be used for beta testing, crash reporting and analytics as well.

Use of Testing on Apps

A Team of testers can be created to work on different jobs. Distributions lists can be created to communicate with testers and send them notifications on the new upload and send it to them. But one has to be sure that the devices that are registered are defined in the apple website for developers on the provisioning portal.

A network of beta testers can be created with the assistance of this app and ask them to test an app that is been recently built. But, the users are now required to visit the website from their devices for viewing available build of applications. An URL can be shared with colleagues if one wants to advertise a beta campaign. Besides, the failed uploads of apps an also be removed effectively.

The Crash Report Feature of TestFlight

Interestingly all the TestFlight features for devices come at no charges to the clients. Feedbacks can easily be availed with help of the dashboard feature.

The Report feature provides a black box for beta testing transparency that assists a user to see which testers have received the apps.  All these can be worked upon effectively on Android and iOs platforms.

The TestFlight SDK is one of well accepted SDK’s across the globe for iOs and Android, where it helps in tracking the work of testers, their progress, and identifies the crashes with required check points.

Other Advantages of Using TestFlight

The crash reports are given to the user with snapshots and full session activity. Remote logging is made possible in this app so that users can log in from anywhere and view the testing activity. Also, Flight Path, the real-time analytics engine gives a close assessment about audience behaviours and production clashes that is important for any developer or tester of smart phones.

The other features and advantages of the TestFlight apps are:

  • Email builds notifications
  • Active Sessions
  • Email Feedback
  • Checkpoints
  • App updates and feedback
  • Effective crash reports
  • API uploads

This is why the Test Flight app has been popular among testers and developers of smartphone apps.
