We investigated why the Veepoo SDK is not working with our H59_A802 fitness band, and here are the findings:
• The Veepoo SDK is hardcoded to look for the following BLE services/characteristics:
• Service: f0080001
• Characteristics: f0080002 (write) and f0080003 (notify)
• Our band does not expose these services. Instead, it exposes:
• 6e40fff0 → UART service (with 6e400002 for write and 6e400003 for notify)
• 0000fee7 → Vendor-specific service (commonly used in Realtek/JL chipsets)
• Because the expected f008000x services are missing, the Veepoo SDK cannot initialize communication and always fails at the connection/authentication step.
✅ Conclusion:
The H59_A802 device is not a Veepoo-compatible band. The Veepoo SDK will never work with this hardware because the communication protocol is different.
To support this device, we need to:
1. Bypass the Veepoo SDK and use a direct BLE client (e.g., via flutter_blue_plus).
2. Send/receive data through the 6e400002/6e400003 UART characteristics or the 0xFEE7 service.
