BLE Gateway Setup for Fitness Bracelet

We are seeking an experienced developer to assist with setting up a Bluetooth Low Energy (BLE) gateway solution that will enable continuous data transfer from a fitness bracelet (manufacturer SDK/API provided) to our cloud server.

Scope of Work:
1. Consultation & Device Selection
• Assess available BLE/Wi-Fi gateway devices in the market (e.g., ESP32-based ready devices or commercial BLE gateways).
• Recommend the most suitable gateway hardware considering scalability, reliability, and ease of integration.
2. Gateway Setup & Configuration
• Configure the BLE gateway to pair with the fitness bracelet.
• Ensure stable connection and proper data forwarding to the cloud server.
• Apply necessary network and security configurations.
3. SDK & API Integration
• Review and implement the SDK and API provided by the bracelet manufacturer.
• Develop or customize middleware to handle data flow from gateway to the cloud.
• Ensure data is formatted and transmitted correctly to our cloud endpoints.
4. Cloud Sync & Testing
• Configure data reception on the cloud server.
• Test full flow: bracelet → gateway → cloud server.
• Validate data integrity, reliability, and near real-time sync.
5. Documentation & Handover
• Provide clear documentation for setup, configurations, and integration steps.
• Knowledge transfer session with our technical team for ongoing management.

Deliverables:
• Selected gateway device recommendation.
• Configured and fully functional BLE gateway.
• Successful end-to-end data sync from bracelet to cloud.
• Technical documentation for future reference.

Skills Required:
• Strong experience with BLE technology and gateway setup.
• Familiarity with ESP32 or commercial BLE gateways.
• Experience integrating SDKs and APIs.
• Cloud connectivity and data synchronization.
• Strong troubleshooting and debugging skills.
