IoT and Android: How These Devices Connect and Communicate (with/without Internet)!

IoT and Android: How These Devices Connect and Communicate (with/without Internet)!

IoT is a term that refers to the billions of things (or physical objects) connected to the internet, all exchanging data (in real-time) with other systems or devices. Practically, you can change any physical object into IoT by connecting it to the internet to communicate or control information.

An IoT device could be as simple as a light bulb or as complex as driverless cars, jet engines, or anything that has sensors which collect and transmit data to ensure swift operations.

Additionally, an IoT device can also be that generally doesn’t operate through the internet and communicate within the network, irrespective of human intervention.

Emergence of IoT

While IoT was originated in 1999 by Kevin Ashton, the first IoT gadget came early in 1980 at Carnegie Mellon University. Today, there are approximately 13 billion IoT-connected devices, which by 2030 can rise by 29 billion.

How IoT is Important for SMBs and Other Businesses

The benefits of the Internet of Things for businesses depend on the agility, efficiency and implementation of the businesses. The idea behind this is to allow businesses to have more access to the data, their internally connected systems and products.

The enterprise use of these connected devices has two segments:

  • Industry-specific segment, which includes sensors, real-time location devices for healthcare, for IoT App Development Services and in industries like security systems, smart device monitoring systems, air conditioners, and many more.
  • Cross-industry specific segment, which includes things like personal wellness, smart homes and many other connected devices.

How IoT Devices Communicate?

An ideal IoT landscape consists of a web-enabled smart device that uses embedded systems such as sensors, processors, and communication gear to collect, send, and act on the information/data collected.

By connecting to IoT, the device will be able to process information in real-time.

Android and IoT: How Do They Partner?

IoT (Internet of Things) and Android devices make quite a dynamic duo! These devices leverage Android’s user-friendly interface and robust app ecosystem to provide a seamless experience for users.

Android app development plays a major role in IoT. The communication between IoT devices and Android often happens through wireless technologies like Wi-Fi or Bluetooth, enabling real-time data exchange and remote control.

If you consider IoT market trends, most of the smart devices operate on Android (Google’s most popular operating System). Additionally, IoT devices generate a large amount of data, which you can access and view from anywhere. And, since Android Things preview versions allow developers to access the OpenGL and WebView preview, the Android-IoT due makes complete sense.

Some of the other reasons why this partnership makes sense are:

Android is a Universal Front-end

Android has a well-established app ecosystem; this Linux-based software is open-source, making it accessible to developers to use and customise its source code in any gadget.  Many IoT devices have dedicated Android apps that allow users to easily monitor and control their smart devices. The availability of these apps enhances the interoperability between Android devices and IoT devices. Another reason why IoT developers prefer Android is that it lowers the overall cost of IoT devices, making it affordable for consumers.

Android works on Linux Kernel and uses Java, C, and C++

Android uses Linux kernel, which serves as the core of the operating system. The Linux kernel provides essential functionalities such as hardware abstraction, device drivers, and core system services. Many IoT devices and platforms leverage the Linux kernel for their operating systems due to its open-source nature, stability, and wide device support.

Developing Android applications using software Drivers for sensors or IoT devices

When developing Android applications that interact with sensors or IoT devices, software drivers refers to the specialised code that allows communication between the Android operating system and the sensors or IoT devices.

Use of open-source Protocol libraries like BACnet, BLE, etc

Open-source libraries provide standardised communication protocols that allow devices to exchange data seamlessly. Libraries like BACnet, BLE and more facilitate communication between devices like HVAC systems, wearables, health monitors and more. Propriety protocols on top of interfaces like Ethernet, Internet Protocol, USB, Bluetooth, UART, RS-232 etc. Android is built on Linux Kernel and uses Java, C, C++

Will IoT work Without the Internet?

IoT is also defined as the collection of actuator devices and edge sensors, all connected to cloud-based analytics and computing resources through the internet. However, the edge devices are often involved in various other roles (depending upon the device type), and sometimes serve as the network entry or exit points. The more functions devices need to perform, the more edge systems become reliant. However, not everyone has a direct Internet connection.

This gives rise to the question- can IoT work without the internet?

A study by Statista found that there will be more than 29 billion connected devices, almost six devices for each of the 7.7 billion people on Earth. However, not all these devices directly connect to the internet.

Many devices, like those in homes or factories, connect to a router using a non-IP bus like ZigBee. In this case, the router is the only one staying connected to the internet, allowing it to communicate with the device’s remote components.

Small sensors and similar devices can work better when they’re not directly linked to a powerful internet-based network. This is because having an IP address can make them more vulnerable to hacking. Additionally, some devices might be in remote areas without a consistent and dependable internet connection.

In such cases, there are limited options to log data locally and move it to a location which gives insights and recommendations using a memory stick. Despite the lack of internet, long-distance communications are possible with the right tools. An example is Thingstream, a network based on Unstructured Supplementary Service Data (USSD) communications. USSD provides secure IoT connectivity without relying on the internet.

Due to gateways that work on standard IP networks, IoT devices can easily communicate at a distance of a few kilometres to a specific range depending on the environment.

So, does IoT need the internet to operate?

Even though IoT doesn’t require the internet, its name comes from the fact that it uses similar technology. Think of IoT as objects using internet-like tech, which is valuable even without the internet.

Let’s understand this by taking an example of an ‘automated soil irrigation system’.

In the irrigation system, IoT can track the program activities and its learnings, such as turning the water supply off when the soil is wet, and the amount of water required. But, when you include the internet with the same information, the data from IoT use it to monitor soil and provide real-time insights into the information required for analysis.

How You Can Connect Android Devices With IoT

Connecting Android devices with IoT (Internet of Things) devices involves a combination of hardware and software interactions. Here’s a how you can do:

How You Can Connect Android Devices With IoT

Communication Protocols

Identify the communication protocols supported by your IoT device. Common protocols include Wi-Fi, Bluetooth, Zigbee, MQTT, CoAP, etc.

Develop or Install IoT Apps

Check if there’s a dedicated app for your IoT device on the platform. If not, you might need to develop or install an app that supports your specific IoT device.

Wi-Fi or Bluetooth Setup

For Wi-Fi-enabled IoT devices, you’ll need to connect them to your local Wi-Fi network. For Bluetooth-enabled devices, you may need to pair the devices through the Android Bluetooth settings.

APIs and SDKs

If you’re developing an app to interface with your IoT device, use the manufacturer’s APIs (Application Programming Interfaces) or SDKs (Software Development Kits). These tools provide the necessary functions and methods for your app to communicate with the IoT device.

Cloud Integration

Some IoT devices use cloud platforms for remote monitoring and control. Ensure that you properly connect your IoT device to its cloud service and that your Android app can communicate with the device through the cloud. Cloud integration is very important in API.

User Interface

Design a user-friendly interface in your Android app to control and monitor the IoT device. This could include features like real-time updates, notifications, and remote-control options.
