RE: RTL8723bs Bluetooth - jhawk - 02-23-2017

(02-23-2017, 07:01 AM)xalius Wrote: It's not really a kernel module, the BT/Wifi module has a UART that is connected to ttyS1, and all that project does is provide a way to upload a firmware binary that enables the module to be attached to the BT stack on the Linux side:

/usr/local/sbin/bluetooth/rtk_hciattach -n -s 115200 /dev/ttyS1 rtk_h5 > /usr/local/sbin/bluetooth/hciattach.txt 2>&1 &

If my understanding is correct it should provide the same functionality even if a little oddly. The package as described will insert the (bin) and set up both pieces required to provide linux functionality at boot time rather then the mechanism via the desktop. Yes it is a bit like the chicken and the egg, you must have bluetooth pre configured to see any benefit. Incremental steps in slaying the dragon... movement toward a fully functional OS on new hardware is always a slow and winding road. Not to mention QA aspect. But we enjoy the ride! Please correct me if my interpretation is erroneous.

Hi jhawk,

have you followed the instructions on https://github.com/lwfinger/rtl8723bs_bt?
I needed to copy the following files into "/usr/local/sbin/bluetooth/" after "make" and "make install".
- hciattach.txt
- rtk_hciattach
- start_bt.sh

The scripts has been installed to...
- /usr/local/sbin/pine64_bluetooth.sh
- /etc/systemd/system/bluetooth-module.service

I was able to type some commands in [bluetoothctl]# after copying these files into "/usr/local/sbin/bluetooth/"... BUT!
I don't know what exactly the problem is, but bluez seems to have bugs.

Btw: I'm using longsleep's Ubuntu image xenial-pine64-bspkernel-20161218-1.img
