Driver it seams is not in Kernel 4.2.1 opensuse
I have installed the kernel 4.2.1 on opensuse tumbleweed, and the bluetooth adapter is not found.

I have the same issue on Ubuntu 15.10 with kernel 4.2.0-15-generic #18-Ubuntu SMP x86_64
Please post the configuration of the kernel in some pastebin location. Your distro may have the configuration wrong.
What does being a Linux user have to do with that?
Your distro may put the configuration file in /boot/config-xxxx or it may be found in /proc/config.gz. Post either of those at http://pastebin.com and post the link here.
Without that info, I can do nothing for you.
Thank you for your help.
This is the link of the kernel configuration http://pastebin.com/WK9uHYf1

The configuration looks correct. Using the standard driver in the kernel, please reboot and post the output of the dmesg command in a pastebin document. I need to see the LMP value for your device.
I see no attempt to load the BT. For example, I see the following in my dmesg
[114479.494040] Bluetooth: hci0: rtl: examining hci_ver=06 hci_rev=000a lmp_ver=06 lmp_subver=8821 [114479.494046] Bluetooth: hci0: rtl: loading rtl_bt/rtl8821a_fw.bin [114479.494535] usbcore: registered new interface driver btusb [114479.501081] Bluetooth: hci0: rom_version status=0 version=1 [114479.513040] Bluetooth: hci1: read Intel version: 370710018002030d00 [114479.513555] bluetooth hci1: Direct firmware load for intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq failed with error -2 [114479.513562] Bluetooth: hci1 failed to open Intel firmware file: intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq(-2) [114479.513695] bluetooth hci1: Direct firmware load for intel/ibt-hw-37.7.bseq failed with error -2 [114479.513699] Bluetooth: hci1 failed to open default Intel fw file: intel/ibt-hw-37.7.bseq [114479.640085] Bluetooth: RFCOMM TTY layer initialized [114479.640106] Bluetooth: RFCOMM socket layer initialized [114479.640127] Bluetooth: RFCOMM ver 1.11
Some of that is from the Intel device, but other is from the 8821ae device that I have.
What does 'lsmod | grep btusb' show any output?
Does 'sudo modprobe -v btusb' produce ant output?
Same things on Ubuntu 15.10:
Ubuntu 15.10 latest kernel config: http://pastebin.com/t4A3aSk4 dmesg output (including modprobe at from terminal after login): http://pastebin.com/1Ck8UGvM Output from some commands: http://pastebin.com/SZ1i7x45
I have donne 'lsmod | grep btusb' and I get no output
Then I do 'sudo modprobe -v btusb' and I get:
jordi@linux-g7rn:~> sudo modprobe -v btusb root's password: insmod /lib/modules/4.2.1-1-desktop/kernel/drivers/bluetooth/btintel.ko insmod /lib/modules/4.2.1-1-desktop/kernel/drivers/bluetooth/btbcm.ko insmod /lib/modules/4.2.1-1-desktop/kernel/drivers/bluetooth/btrtl.ko insmod /lib/modules/4.2.1-1-desktop/kernel/drivers/bluetooth/btusb.ko reset=1
then I do again a 'lsmod | grep btusb' and I get:
jordi@linux-g7rn:~> lsmod | grep btusb btusb 45056 0 btrtl 16384 1 btusb btbcm 16384 1 btusb btintel 16384 1 btusb bluetooth 520192 9 bnep,btbcm,btrtl,btusb,btintel
It is clear that btusb and friends are not being loaded automatically, but I do not know why. The device tables in the 4.2 kernel definitely say to probe all devices with vendor 0x0bda and class 0xe0, i.e. Realtek BT devices.
Please post the output of 'lsusb -v -d 0bda:'.
Here you have, thank you for your help

lsusb -v -d 0bda:
gives almost identical output on my Ubuntu kernel. With one tiny difference. A question mark on the first:
bDeviceSubClass 2 ?
I do not know what is wrong. The device table command says to accept any device with class 224, subclass 1, and protocol 1. Your devices match that requirement.
I just wrote a RedHat developer that has this device. Perhaps he has some special insight.
In kernel 4.2.3 source tree, devices with 0bda vendor id are not listed in btusb_table[] but in blacklist_table[] in file btusb.c
thanks. I moved 0bda line over to the btusb_table[] and it's all good now! (it works with RTL8723AU on my Lenovo Yoga 13 + Ubuntu 15.10)
You can explain how to do that? I'm not linux expert and I don't kow how to do it
Hello guys,
I also got the problem that my bluetooth device, a realtek 8723ae, couldn't be detected. I edited the btusb.c file and moved the realtek entries from the blacklist table into the btusb_table, compiled and installed. After a reboot bluetooth works fine. I don't know, why the realtek entries are blacklisted.
@jordirelats You simply have to clone the repo and edit the btusb.c file within the repo. Search for the following line: static const struct usb_device_id blacklist_table[] = {
Below that, you have look for the realtek entries. Delete the realtek entries there and insert them after the following line: static const struct usb_device_id btusb_table[] = {
Save the file, run "make" and "sudo make install" in the repo directory and reboot.
Thanks a lot! It worked!

Hello
Sorry, but what you mention to me is not so easy, I'm just a linux user.
Please you can explain how to do this?
Thank you very much
No, it will not be fixed in 4.3 as the fix was found too late. I just pushed a fix to the kernel branch of this repo. The driver now works for RTL8723BU and should work for RTL8723AU, although I have no hardware for testing.
The kernel branch of the repo now has this fix. It is needed for both RTL8723AU and RTL8723BU. The "unique" feature for these two devices is that they use the same USB ID for both wifi and BlueTooth.
I have tested the kernel branch with rtl8723au and can confirm that it works. This is on a Lenovo Yoga with Ubuntu 15.10 with latest kernel updated from ubuntu repos (4.2.0-17).
I have tested the kernel branch with rtl8723au and can confirm that it works. This is on a Lenovo Yoga with OpenSuse Tumbleweed with Kernel 4.3.0
Do you know in witch Kernel will be solved the issue?
hi, i'm using suse leap with the 4.1.12-1-default kernel and a rtl8723be card.

@leon9923 kind of - the hard way: i've bought a intel wifi card. as direct replacement the 3160 or if you take this as a chance to upgrade (2x2 instead 1x1 as the 3160 and rtl8723, and AC capable): 7260
sorry, for no better solution, but i should have changed immediately to an intel card, instead of wasting time with realtek. right now they are between 16 und 22 € on amazon
