BMS App API for Native APP Development

Problem

• The mobile BMS application required a unified communication layer capable of bridging Flutter with native Android and iOS battery management interfaces.
• Native BLE communication, firmware update handling, and diagnostic command processing differed significantly between Android and iOS platforms, creating complexity in maintaining consistent cross-platform behavior.
• The system required reliable real-time BLE communication for battery diagnostics, firmware updates, command encoding/decoding, and device response handling while minimizing platform-specific implementation overhead.

Approach

• Developed a custom Flutter plugin to bridge Flutter application logic with native Android and iOS BMS communication interfaces.
• Implemented platform channel architecture enabling secure bidirectional communication between Flutter UI and native BLE services for diagnostics, firmware updates, and battery telemetry handling.
• Designed native communication modules for BLE read/write flow, diagnostic command construction, firmware update transfer, response decoding, auto-reconnect handling, and integration with backend APIs for diagnostic configuration and firmware retrieval.
