Hi,

 

Do go through the first post, as I have updated with the steps to make RTL8723DE Bluetooth to work. IF yours is RTL8723DE and the log shows rtl8723be firmware is wrongly loaded, it can be fixed by copying rtl8723d* firmware to the /lib/firmware/<relevant directory>. You can download rtl8723d firmware using git and copy to the directory. That will be enough to enable Bluetooth.
