AI Technical Summary
BLE suffers from data packet loss, latency, connection interruption, and "false connection" phenomena in battery management systems. Furthermore, it lacks application-layer integrity verification and connection self-recovery mechanisms, which affect the accuracy of battery data acquisition and system reliability.
Data transmission is performed using the BMS protocol frame structure. Notify and Write features are used for command issuance and data return. A connection self-recovery mechanism is built through periodic handshakes, timeout retries, and CRC checks to ensure data integrity and communication stability.
It improves the stability and security of Bluetooth communication, enabling reliable transmission of battery data in complex wireless environments, preventing unauthorized device access, and achieving system self-healing recovery.
