Smart Lighting Solution using BLE mesh network with Android and iOS app development

Client Overview

US-based technology company offering innovative energy-saving power solutions. Its products include dimmable electronic ballasts and electronic transformer.

Technology & Business Requirements
  • Required converting legacy devices into smart, connected ones through a unique mesh-based architecture
  • Client wanted a smart lighting solution free from the dependency of cloud and gateway and just connecting it to smartphones over BLE
VOLANSYS Contribution
  • Designed, developed and validated BLE module to provide desired connectivity with mesh algorithm
    • Control dimmer circuit and ON/OFF functionality
    • Support BLE mesh up to 24 units/dimmer (each dimmer connects with single application)
    • Worked on nRF5 SDK and provided business logic to develop BLE mesh algorithm
  • Implemented and suggested innovative QR code approach to maintain user management, synchronization, and real-time data
  • Designed and developed hardware architecture
    • Class A component selection
    • PCB layout and schematics
  • Hardware prototyping
    • PCB fabrication and assembly
    • Board bring-up test cases and test reports
  • Developed test scripts for FCC pre-compliance testing
  • Designed and developed firmware on Nordic’s development kit for parallel prototype development to match with hardware lifecycle timelines – mesh provisioning support, dimming support, group and scene scheduling
  • OTA support
  • Porting on hardware prototypes and bring-up of peripherals
  • Developed and deployed BLE based Android & iOS mobile app to control the LED devices
    • Custom UI/UX that can be white-labeled
    • Features support – OTA (Over The Air), popup, alerts, device/ user/ group management, module to app pairing encryption
