Windows 10: Bluetooth connect for JBL Go3

I have an HP Pavilion G7 laptop and a JBL Go3 speaker. All drivers appear to be present and current. The speaker is paired with the laptop but when I try to connect the system tells me that my device does not support Miracast? and won't connect! Why would I need Miracast for a speaker anyhow?

Can't connect JBL Flip 4 to Bluetooth

I borrowed a JBL Flip 4 to try out on my Dell Workstation. I have Bose QC-35 headphones connected through Bluetooth to the Dell. I was able to pair the JBL Flip 4 to my Dell - but it wouldn't connect. I got the error message "Error Establishing Connection." Since the Bose headphones work, I don't know why the JBL speakers won't connect. They connect fine on my friend's computer W10. Windows 10 latest version. Any advice, please?

 

JBL Bluetooth speakers not connecting

Yes, I tried all that. I ran the Hardware & device troubleshooter -no problems found. I also right clicked on the JBL driver in device manager, clicked update driver, it said it already had the best one. I then uninstalled the device, restarted Windows,
tried to connect the speakers again, they pair, but will not connect, even though I get a Windows notification saying that they are connected. They come up listed in the "other devices" screen on the Bluetooth settings, not under the "audio" tab, or screen.

I also tried the Bluetooth troubleshooter, it reports a problem with Bluetooth radio? which it can't repair, then disconnects or turns off Bluetooth, and doesn't do any more. If I turn Bluetooth back on again, my Bluetooth designer keyboard & mouse works
again, but not the JBL speakers. The frustrating thing is that they worked perfectly 3 or 4 weeks ago when I went on holidays. I have changed nothing on the system hardware wise. I also followed the prompt to the "Windows update" setting, it reports that everything
is up to date
