I have this device, but the driver requires a firmware file (rtl8821a_config.bin) which does not seem to exist. Looking at the code[1], there appear to be several firmware config files for variants of this device: + switch (lmp_subver) { + case RTL_ROM_LMP_8723B: + cfg_name = "rtl_bt/rtl8723b_config.bin"; + break; + case RTL_ROM_LMP_8821A: + cfg_name = "rtl_bt/rtl8821a_config.bin"; + break; + case RTL_ROM_LMP_8761A: + cfg_name = "rtl_bt/rtl8761a_config.bin"; + break; + case RTL_ROM_LMP_8822B: + cfg_name = "rtl_bt/rtl8822b_config.bin"; + break; However, the only file that seem to actually exist is rtl8822b_config.bin. Does anyone know where to get the others?
