I've tried= an updated version for this adapter (2020/12, from the folder name contained in it) specific for linux from XMPOW: https://mpow.s3-us-west-1.amazonaws.com/mpow_BH519A_driver+for+Linux.7z And replaced _fw.bin and _config.bin, but nothing changed. Then I've found this post on github: https://gist.github.com/peteristhegreat/b48da772167f86f43decbd34edbd0849 After ordering by date on Microsoft Catalog for "realtek bluetooth", and a dozen downloads, I've finally found a package that contained the firmware version for this rtl8761b, this specific package: https://www.catalog.update.microsoft.com/ScopedViewInline.aspx?updateid=3Db= 103336e-5da4-4b03-ad04-7224d591aadd, download link: http://download.windowsupdate.com/d/msdownload/update/driver/drvs/2021/05/c= a0e770c-6a5d-4de0-b37a-f4b91cccd8c3_7778831d2b9d721cf94d5a8d8c0676ff1b96c87= 4.cab This has a date of 26/04/2021, and after extracting rtl8761b_mp_chip_bt40_fw_asic_rom_patch_new.dll and renaming the same file = to rtl8761b_fw.bin and replacing the file contained in /lib/firmware/rtl_bt/ a= nd deleting the rtl8761b_config.bin file (AFAIK, Windows packages from Realtek doesn't come with a config file, but besides an error in kernel the _bin is sufficient) my adapter works wonderfully. No issues on reconnecting, no iss= ues after reboot, the adapter works correctly. Instead of forcing users to randomly download Windows drivers from the web = in home to find a working and updated version for this device, can Realtek add= the firmware and kept in sync with the Windows version as it does do with the others bluetooth devices supported in kernel? Any way to contact them? Anyway, for the people who have this issue, try the version linked above. Marco. --=20 You may reply to this email to add a comment.
