The Realtek RTL8723B Bluetooth chip requires both the firmware file rtl8723b_fw.bin and the configuration file rtl8723b_config.bin to function properly. Currently, Fedora’s linux-firmware package only includes the firmware file rtl8723b_fw.bin, but the configuration file rtl8723b_config.bin is completely missing. This results in firmware load errors and causes Bluetooth to either not work or be unstable. The following message appears in the system log (dmesg): bluetooth hci0: Direct firmware load for rtl_bt/rtl8723b_config.bin failed with error -2 This issue affects many users with the RTL8723B chip. I kindly request that the missing configuration file rtl8723b_config.bin be included in the linux-firmware package to enable Bluetooth to work without manual intervention. Reproducible: Always
It works fine for me on my arm devices with the rtl8723bs, it's in the realtek-firmware package [ 40.679480] Bluetooth: hci0: RTL: examining hci_ver=06 hci_rev=000b lmp_ver=06 lmp_subver=8723 [ 40.698379] Bluetooth: hci0: RTL: loading rtl_bt/rtl8723bs_fw.bin [ 40.723905] Bluetooth: hci0: RTL: loading rtl_bt/rtl8723bs_config.bin > This issue affects many users with the RTL8723B chip. Which variant of the 8723B do you have?
Does it work if you run this and reboot? sudo ln -s /lib/firmware/rtl_bt/rtl8723bs_config.bin.xz /lib/firmware/rtl_bt/rtl8723b_config.bin.xz
