AI-WB2-12F电脑蓝牙连接秒断，手机搜索不到

AI-WB2-12F电脑蓝牙连接秒断，手机搜索不到，而且识别为心率测试仪设备，怎么回事

模块型号：AI-WB2-12F
固件版本：release/V4.18_P23.2.1
编译时间：Dec 16 2024 13:38:22
AT版本：V4.18_P3.0.0
SDK版本：release_bl_iot_sdk_1.6.40

问题：BLE连接5秒自动断开

详细测试：
1. 信号强度：-11dBm（极佳）
2. 连接参数：已设为24,48,0,2000（20秒超时）
3. UUID配置：尝试了FFE0/FFE1/FFE2、交换RX/TX、默认UUID等
4. 透传模式：已禁用自动透传（AT+TRANSENTER=0,1）
5. 事件日志：开启所有日志，只有CONNECT/DISCONNECT事件
6. 错误现象：无论何种配置，固定5秒断开

已排除：
- 硬件问题（信号强度证明）
- 配置问题（多种配置测试）
- 环境干扰（近距离测试）
