android Bluetooth Low Energy Issue

Hi, all.
Im udoo quad noob. And I Have a Question.
I downloaded the Android 4.3 version (udoo_dual_android_v2.0.2.zip) from udoo website
burn with windows image maker tool into sdcard.

:?: :?: :?:
My Bluetooth Dongle is CSR4.0 usb chip.
But my custom android Bluetooth low energy application is not working properly.
Nothing is outcome from android bluetooth driver.

Samsung Galaxy S3 LTE, LG G3 is working great with my custom application.

How Can I enable Bluetooth Low Energy for udoo quad?
