Dears, I'm trying to backport a latest bluetooth subsystem to 3.4 kernel to use the BLE and LEAdvertisingManager1. I think backport is success, but 'LEAdvertisingManager1 interface not found' error still occured. My step is below: ###To compile old kernel $ export ARCH=arm $ export CROSS_COMPILE=$CCPREFIX $ cd $KERNEL_SRC KERNEL_SRC$ make defconfig KERNEL_SRC$ make KERNEL_SRC$ make INSTALL_MOD_PATH=$OUTPUT install ###To backport $ export KLIB=$KERNEL_SRC $ export KLIB_BUILD=$OUTPUT $ wget http://www.kernel.org/pub/linux/kernel/projects/backports/stable/v4.1.1/backports-4.1.1-1.tar.xz $ unxz backports-4.1.1-1.tar.xz $ tar xfp backports-4.1.1-1.tar $ cd backports-4.1.1-1 backports-4.1.1-1$ echo "CPTCFG_BT=m > CPTCFG_BT_RFCOMM=m > CPTCFG_BT_BNEP=m > CPTCFG_BT_BNEP_MC_FILTER=y > CPTCFG_BT_BNEP_PROTO_FILTER=y" > defconfigs/bluetooth backports-4.1.1-1$ make defconfig-bluetooth backports-4.1.1-1$ make backports-4.1.1-1$ make install ### replaces a existed kernel with $KERNEL_SRC/arch/arm/boot/zImage ### replaces a existed /lib/modules with $OUTPUT/lib/modules ### and execute command 'depmod -a' and reboot ### After reboot, excute test/example-advertisement ### output message is 'LEAdvertisingManager1 interface not found' Am I missing some configuration or doing wrong step? or cannot use 'LEAdvertisingManager1' by backport? Please advise me.
