Nowadays, users demand quick and easy access to services they need, without downloading the full version of an app. App Clips - a feature introduced by Apple on iOS 14 - offers a solution to this demand by enabling users to access a small part of an app. By integrating your Bluetooth-enabled app to App clip, you can take user experience to the next level. This opens up new possibilities, such as allowing users to connect to nearby devices, perform a specific feature, and more. In this tutorial, I’ll guide you through integrating Bluetooth into your App Clip. Whether you’re a seasoned developer or a newbie, you will find everything you need to get started. So, let’s dive in!

Have you ever wanted to create a web application that enables users to communicate with your device using Bluetooth? Until the introduction of Web Bluetooth, this was only possible through native mobile apps. However, with the advent of Web Bluetooth you can now turn your idea into a reality.
Web Bluetooth is a game-changing technology that allows web developers to connect their applications directly to Bluetooth devices, opening up a wide range of possibilities for IoT, wearables, and other Bluetooth-enabled devices. By leveraging the power of Web Bluetooth, you can create web applications that can communicate with devices without the need for a separate native app.
So if you have been dreaming of creating a web application that can interact with Bluetooth devices, now is the time to explore the possibilities of Web Bluetooth and take your development skills to the next level.

When developing a new feature of our software, we tend to search if there is a “similar” library or framework available in the community to reuse it. No one like to reinvent the wheel, dont you? 😉 However, the lib that most fits our requirement sometimes does not support a feature you need or just a custom property. You can open a pull request to the original repo, but it might take time and depend on the author whether he approves your changes or not. In that case, you can create your own library from the original one, we named it “Fork” process.
In this post, I will shortly summarize steps to publish a library to npm, and tell you about a story that I faced when using React Native Wheel Picker library.

When it comes to mobile technology, iOS and Android are the two dominant operating systems that power the majority of smartphones and tablets worldwide. As developers, it is essential that we have the knowledge and tools to work with both platforms effectively. This is especially true when it comes to utilizing Bluetooth technology, which is a crucial component of many modern mobile applications.
In part 1 of this tutorial series, we created a BLE (Bluetooth Low Energy) framework that could be connected to the UI using React Native. However, this framework only worked on iOS, which meant that we needed to develop a separate solution for Android.
In part 2 of this tutorial series, we will be focusing on defining a new SDK for Android and linking it to the UI, just as we did on iOS. This will allow us to fully support both operating systems and provide a seamless Bluetooth experience for all users, regardless of their device of choice.

I have been working in mobile development on both native projects and cross platforms (React Native, Flutter), and I also have experience working on BLE. Sometimes I get emails asking about the communication of RN/Flutter to BLE. Thus, I decided to introduce this series React Native and BLE to guide you on how to develop a native BLE framework and connect it to React Native.
Of course, there will be another series for Flutter and BLE after finishing the series of React Native.
In this series, I will guide you through a completed process from development to distribution.

In the ever-evolving world of mobile app development, keeping users engaged and informed is key. For iOS developers, background notifications are a powerful tool that enhances user experience without interrupting their current activities. But what exactly are background notifications, and how do they work? Let’s dive into the details.

After years of working in BLE technology, I found that despite there are many applications helping to test BLE devices but none of them performs their roles well. That’s why I decided to implement a BLE application on my own - Dark Hat. The core objective of this application is to share a better tool with you - an engineer working in BLE field.

Push notification allows your app to reach users more frequently, and can also perform some tasks. In this tutorial, we will learn how to config apps to get remote notifications, display contents and then perform some actions when the user presses in.
Let’s get started.

Ever wonder why your app gets killed from the system when it enters the background? This post is going to summarize the top reasons introduced by Apple in WWDC 2020, and what you can do to prevent your app from being killed in the background. By applying these tips, we can improve our app’s experience because your app does not have to re-launch from the scratch.
Let’s rock!

Unlike Android, iOS has restrictions for the use of background processing in an attempt of improving battery life and user experience. When your apps enter to background mode, it’s time developers get out of control of their app. How and when your app gets a chance to execute your task totally depends on the system. At the heart of iOS, Apple uses its own internally-complex algorithm to determines which apps are allowed to run in the background, based on various factors such as the pattern of user activity, current battery state, etc.
In this tutorial, we will learn how to request periodic execution time on iOS. After understanding how it works, we will apply this technique to a BLE-based app in some specific cases in the next tutorial.
Let’s rock!
