1 GFPS legacy pair 搭配支援LEA手机不连 legacy profile(A2DP/HFP)

耳机端走的是GFPS legacy pair， 和支援LEA的手机做initial pair， 支援LEA的手机不连legacy profile,

测试发现：

打开legacy CTKD LE 的功能之后  支援LEA的手机就会来连legacy profile

关闭 legacy CTKD LE 功能之后， 支援LEA的手机就不会来连legacy profile

[BBPRO3BUG-24407] [BBPRO3][EVB][E Cut][3.15.0.5+TestBin][Single]配置Finder，耳机开机进配对，无法连接到Find Device - Jira

//Conclusion:

The uuids are not passed to upper layer.

The build seems to be old and there have been changes in this module, please check if it is repro in the latest build.

If reproducible, please provide bug report along with issue timestamp/video.

Steps to enable full bt_snoop logs:

1.Enable Developer options on the device.

2.In the Developer options menu, change the Enable Bluetooth HCI snoop log setting to Enabled.

3.In the "Logger buffer sizes", change the buffer size to "16M"(or highest possible).

4.Enable Verbose Logging from Developer Options (Developer Options -> Enable Bluetooth Stack log -> Select Verbose)

5.In the "Store logger data persistently on device" to  "All log buffers"

6.Restart your phone for logging to take effect

7.Try reproducing your issue again and take a new bugreport
