    Lubuntu 20.04 bluetooth devices not detected

    Hello,

    On a new install of Lubuntu 20.04 LTS my bluetooth devices are not detected either with BlueDevil Wizard or with Blueman bluetooth manager. Neither is my laptop visible to my phone, although in Blueman I have selected "Always visible".

    Yes, my devices are turned on. Yes, my laptop has bluetooth capability. Yes, my wireless connection is working.

    Please help me solve this problem. What info do you need to help me and how do I get it?

    Many thanks.

    Wondering why no replies (except my own!). I have looked at other people's questions about bluetooth problems and it seems few people find help here. Does nobody in here know anything about bluetooth?

    For anyone else in the same situation...

    I needed to download a driver.
    The solution is here:

    It appears that github is specific to Broadcom, as also per your listing.
