在Android源代码中启用Bluez内核日志

Question

I am working on Bluetooth application and need to get the native Bluez stack.

Can any one give any pointers to do so? I have complete source code with me so if I need to modify any file and build the code again then that will also help.

Thnaks in Advance.

1. Ensure CONFIG_DYNAMIC_DEBUG is set as "CONFIG_DYNAMIC_DEBUG=y" in your config file.
2. start the complete build and flash the binary images to the target.

3. Open ADB command prompt and type the following sequence of commands:

   • Mount debugfs interface adb shell "mount -t debugfs debugfs /sys/kernel/debug"

   • Enable Debug logs for the module adb shell "echo -n \\"file +p\\" > /sys/kernel/debug/dynamic_debug/control"

   • Save Kernel Logs adb shell "cat /proc/kmsg > sdcard/myl2cap.log"
