Industrial Smart BMS Gateway & Mobile App with BLE

battery management system (BMS) via CAN, RS485 protocols from the cloud via Ethernet (MQTT/HTTP + SSL/TLS) and from a mobile application via BLE (GATT)

Droid Technologies designed and developed a smart Battery Management System (BMS) gateway and companion mobile application for monitoring, configuring, and controlling multiple battery systems.

The device acts as a BLE/Ethernet BMS controller, communicating with battery management systems through CAN, RS485, and RS232 interfaces. It supports Ethernet connectivity for reliable network communication and secure data exchange with local or cloud platforms using MQTT and HTTP/HTTPS with SSL/TLS encryption.

The companion mobile application is used for device setup and configuration over Bluetooth Low Energy (BLE), allowing users to connect to the gateway, configure network and system parameters, monitor device status, and simplify commissioning in the field. An integrated NFC tag enables fast BLE pairing and easier device setup.

Droid Technologies delivered hardware design, PCB development, embedded firmware, BLE communication, industrial interfaces, secure networking, NFC integration, and mobile app development.
