Flutter & React Native App Development for IoT Devices

Our Mobile App Development Service for IoT Devices using Flutter and React Native aims to give you secure connectivity. We enable real-time communication and offer scalable cloud solutions to help you launch your applications in a production-ready state.

There are many types of businesses that rely on the Internet of Things (IoT), including healthcare, sports, manufacturing, smart homes, and industrial automation. However, without a solid and scalable mobile app to deliver the data, all that hardware will not provide any value.

A great mobile app will be your control center for IoT devices. It will offer data visualization and connect users to their devices. It will also serve as your communication bridge.

Case Study: Lithium Battery IoT App Development
Using Flutter (BLE Integration)

We just completed development of an advanced app using Flutter and BLE integration for lithium batteries by aligning with our client's technology preference. We also have multiple IoT/mobile apps developed in React Native listed in available case studies, demonstrating strong capability in both frameworks as well as the ability to utilize the appropriate choice of technology based on project objectives, overall performance desire and client's strategic plans.

Lithium Battery App

Project Summary

We were asked to create a dedicated cross-platform mobile app on behalf of a lithium battery manufacturer.

The app was needed to replace their WeChat mini-app, and the lithium battery system has a BMS (battery management system) which uses the CAN-BUS protocol, and the system also contains a BLE module (Bluetooth Low Energy), which is used for wireless communication with the mobile app.

The purpose of this project was to create a branded production-ready Flutter application (cross-platform) that can be host for iOS & Android devices that allow users to view live battery data in real-time.

Lithium Battery IoT App Development

BLE Integration

Using Flutter BLE libraries, we implemented:

  • Device scanning filtered by service UUID
  • Secure BLE connection with timeout handling
  • Auto-reconnection logic for stability
  • MTU negotiation for optimized packet size
  • Real-time notification subscription

To ensure reliability, we added checksum validation before processing any packet. This prevented corrupted or incomplete data from being displayed.

Technical Approach

To ensure that we could provide a high-performance single code base for both platforms, we chose to use Flutter to develop this application. The structure of the app follows the Clean Architecture principles by separating the communication with the BLE module, the parsing of data from the BMS and the user interface allowing for scalable and maintainable development.

The client provided communication protocol documentation. Our team analyzed:

  • Packet structure (Header, Command, Payload, Checksum)
  • Byte order (big-endian/little-endian)
  • Signed vs unsigned integer values
  • CRC validation logic

We developed a packet parsing class in Flutter that will take the raw HEX data received from the BLE module and output structured battery metrics.

Core Features Delivered

The mobile dashboard displayed:

  • State of Charge (SoC %)
  • Voltage (V)
  • Current (A) with charging/discharging indicator
  • Cycle count
  • Cell voltage status

The UI was designed with a clean, modern Western-style interface, including large SoC indicators, real-time refresh animations, and dark/light mode support.

Testing Strategy

As there was limited access to hardware, the following measures were put in place to facilitate continued software development:

  • Mock BLE simulator for providing sample battery packets
  • A data-injecting layer to allow for testing of parsing in isolation
  • Edge case testing for low battery voltage, high current and error states

To perform final validation, the client shipped us the BMS module and we were able to do real device testing to confirm that the signals were stable and performed adequately.

Security & Performance

We ensured:

  • Secure BLE pairing
  • Encrypted local storage
  • Efficient stream management
  • Optimized state updates to reduce battery drain
  • Stable background reconnection handling

Launch

We provided a complete solution for launching this app in both Google Play and Apple App Store. Included was managing all permissions, privacy requirements, issuing certificates for signing, and conducting beta testing.

Outcome

Our client has replaced their WeChat mini-app with a fully branded and production-ready Flutter-based IoT application that provides reliable long-range Bluetooth communication with the device, accurate battery level information, and an expandable architecture to accommodate future updates to the firmware or new features.

This project demonstrates our deep knowledge of Flutter-based IoT app development, handling BLE not connected appropriately when communicating between the mobile application and the device(s) and parsing data sent from microcontrollers in order to integrate products designed and built using conventional materials into a new cutting-edge product using advanced technology and methods of automation.
