Bluetooth failure: Failed to load rtl_bt/rtl8821a_config.bin #105

Open cg3dland opened 3 years ago

The following messages are printed out with the rtl8821cu driver 8821cu.ko when the Nano boots:

bluetooth hci0: Direct firmware load for rtl_bt/rtl8821a_config.bin failed with error -2 bluetooth hci0: Falling back to user helper Bluetooth: hci0: Failed to load rtl_bt/rtl8821a_config.bin Bluetooth: hci0 command 0xfc20 tx timeout Bluetooth: hci0: download fw command failed (-110)

I could not find the rtl8821a_config.bin from the rtl8821cu driver source tree, where could I find this file?

You could try to find and download btrtl_8821c.tar.bz2, build it, and copy the new driver ko file and bin files into right directories.

Is there a link to download btrtl_8821c.tar.bz2 ?
