Is the following file present in your device?
system/etc/permissions/android.hardware.bluetooth.xml
If not modify your device.mk to copy this file over.
e.g:
1. PRODUCT_COPY_FILES += \
2.
frameworks/native/data/etc/android.hardware.bluetooth.xml:system/etc/permissions/android.hardware.bluetooth.xml
