rtl8723be (0bda:b001) bluetooth doesnt work on linux-4.6.0-1-amd64

[xundeenergie]

Hi There!

I have this combinated WIFI/Bluetooth-Adapter on my HP ProBook 450 G2. And it worked for a long time, since Kernel 4.0 (i think i remember correcktly)

Now it stopped working on Debian stretch with kernel 4.6.0-1, also with Kernel 4.5

# lsusb
Bus 001 Device 002: ID 8087:8000 Intel Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 004: ID 062a:4101 Creative Labs Wireless Keyboard/Mouse
Bus 002 Device 003: ID 05c8:0374 Cheng Uei Precision Industry Co., Ltd (Foxlink) 
Bus 002 Device 002: ID 0bda:b001 Realtek Semiconductor Corp. 
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I compiled and installed the rtlwifi from the troy-branch, and i can see my laptop on my mobile-phone, but i'm not able to pair the devices. The laptop does not recognize the mobile-phone on bluetooth.

Installing this driver nothing happens.

Do you need more infos

Best regards

Jakob

I tried rtlwifi from kernel-branch on
# uname -r
4.6.0-1-amd64

after compiling and make install i removed the module with

modprobe -rv btusb

Then i reloaded the module

# modprobe -v btusb
insmod /lib/modules/4.6.0-1-amd64/kernel/drivers/bluetooth/btintel.ko 
insmod /lib/modules/4.6.0-1-amd64/kernel/drivers/bluetooth/btbcm.ko 
insmod /lib/modules/4.6.0-1-amd64/kernel/drivers/bluetooth/btrtl.ko 
insmod /lib/modules/4.6.0-1-amd64/kernel/drivers/bluetooth/btusb.ko 

journalctl -f gives me:
