Product Summary

EXHILR required a connected wearable ecosystem that could transform LED shoes from a fashion product into an interactive digital experience. The goal was to enable users to personalize shoe lighting, sync LED effects with music, locate friends during festivals, and purchase products through an integrated e-commerce platform.
smartData proposed a mobile app, SDK, Shopify-powered e-commerce website, and backend admin panel to support BLE-based shoe control, GPS-enabled social tracking, OTA firmware updates, diagnostics, order management, delivery tracking, and product administration.
The solution creates a scalable IoT and FashionTech platform combining wearable hardware, mobile engagement, social connectivity, and direct-to-consumer commerce, helping EXHILR deliver a differentiated lifestyle product for entertainment, events, and experiential retail markets.

Features

• BLE LED Shoe Control : Mobile-based control for LED modes, brightness, colors, presets, and left/right shoe synchronization
• Music Sync & Custom Lighting Effects : Real-time LED effects synchronized with music, movement, and user-defined lighting patterns
• GPS-Based Festival Friend Tracking : Location sharing, friend trails, proximity alerts, and event group visibility for crowded venues
• SDK & OTA Device Management : Secure BLE SDK for diagnostics, firmware updates, battery status, device health, and configuration control
• Shopify E-commerce & Admin Operations: Product catalog, checkout, order tracking, delivery API integration, inventory, analytics, and firmware/content management

Technical Challenges

• E-commerce, delivery, and device ecosystem integration : Integrated Shopify, payment gateways, delivery APIs, admin workflows, firmware/content management, analytics, and device telemetry into one scalable platform
• BLE latency and LED sync in crowded environments : Implemented custom GATT communication, chunked data transfer, command queues, and acknowledgement-based flow control to maintain reliable LED control with under 200ms latency
• Battery drain from LEDs, GPS, microphone, and BLE usage : Designed adaptive energy modes including Performance, Balanced, and Eco with dynamic GPS sampling, LED brightness throttling, and BLE wake-up optimization
• Secure shoe pairing and unauthorized device control risks : Enforced QR/passkey-based secure bonding, signed BLE write operations, encrypted GPS exchange, and restricted pairing to predefined friend groups
• Cross-platform SDK consistency for iOS and Android : Built a modular SDK with React Native integration and native Swift/Kotlin bridges to standardize BLE, GNSS, diagnostics, OTA, and device configuration APIs
