    Help with bluetooth

    I purchased a bluetooth adapter:

    https://www.amazon.com/Bluetooth-Ada...tooth+bcm20702

    which says it is based on Broadcom BCM20702, whatever that means. ALso says it works with Linux. But when I plug it in, the system does not detect it.

    I found a monitor command, btmon, which gives this:

    $ sudo btmon
    Bluetooth monitor ver 5.37
    = New Index: 00:19:86:00:1B:15 (BR/EDR,USB,hci0) [hci0] 0.418309
    = Open Index: 00:19:86:00:1B:15 [hci0] 0.418310
    = Index Info: 00:19:86:00:1B:15 (Broadcom Corporation) [hci0] 0.418310
    @ New Settings: 0x0ad3
    powered connectable bondable ssp br/edr le secure-conn
    < HCI Command: Write Scan Enable (0x03|0x001a) plen 1 [hci0] 112.492666
    Scan enable: Page Scan (0x02)
    > HCI Event: Command Complete (0x0e) plen 4 [hci0] 112.493336
    Write Scan Enable (0x03|0x001a) ncmd 1
    Status: Success (0x00)

    System settings > bluetooth > devices tells me:

    Your default Bluetooth adapter is not visible for remote devices.

    I am running Linux jon-neon 4.4.0-77-generic #98-Ubuntu SMP

    Knowing almost nothing about bluetooth, I am stumped. Help, please. Thanks in advance.

    Not sure where you are getting that, as in the Product Description > System Requirements it states:
    OS Supported: Microsoft Microsoft Windows XP/Vista/Win7/Win8/Win10
    Not compatible with Mac os or USB 3.0

      Well, on the Amazon page, one use says it works out of the box on Linux.

      So do you know one which does work on LInux? There is on called Plugable on Amazon which Amazon says works with Linux, but the user comments say otherwise.

      There is an Ubuntu page which gives a list, but those are models which are hard to find on my (eastern) side of the Atlantic. I'll keep lookin'.

        P.S. It is very tiring going thru a list of approved adaptors and looking each one up on the Internet, only to find it is not available.

          From a Google search, finding:
          https://wiki.ubuntu.com/HardwareSupp...othUsbAdapters
          Which has a link to:
          http://www.thinkpenguin.com/
          Where I see:
          https://www.thinkpenguin.com/gnu-lin...-micro-adapter

          It’s priced the same as the one you bought on Amazon (before the deep discount Amazon offered of course), but it specifically lists all the Linux distriubtions (by release version) it works on.

            Well, 60$ is a lot more than 10€. Plus I have to order it from the US. I can't find it at all over here (France). missed that link when I got lost in the list on the right.

            Thanks for the tip.

              After you plug it in does "sudo lshw" show it?

              The following link
              https://ubuntuforums.org/showthread.php?t=2254759
              solved their problem with this device by
              I solved the problem by re-compile kernel with customized patch. But it won't stay after kernel update.
              And, you might try the suggestion given here:
