Asking for help not an issue

Viktor I am trying to use a pi with a low cost bluetooth speaker / mic

Even after installing ofono and doing the usual with a bluetooth dongle I am still struggling to force hsf/hsp mode.

I can get a phone to connect to the Pi via Hsf/hsp but getting the pi to connect to headset is driving me nuts!!! :)

If you have any guides or tips please share.

PS as an afterthought have a look at https://mycroft.ai/ as it might be a great combo for your HUD

That's an interesting one.. I've never actuallt tried this yet, but here are my thoughts:
I'm not sure if you can connect two devices to the same bluetooth adapter, but if you're using the dongle to connect the phone, then you can use the Pi's built in bluetooth adapter to connect to the speaker.

If you enter the bluetooth tool bluetoothctl and give it the list command it should give you a list of all available adpaters, then select the adapter with the select MAC-ADDRESS-OF-ADAPTER. After that you can try pairing the speaker as normal:

Let me know if some of this is not working. Might have a bluthoot speaker somewhere, but not tried this yet.

Basically a headset Victor that is all they are https://www.ebay.co.uk/itm/Luminous-Lights-Rechargeable-Wireless-Bluetooth-Speaker-Portable-Mini-Super-Bass/402115969460?

With PA 12 they changed the priority and because many would stick in HSP/HFP profile,
They have swapped it round and now I can not seem to get it out of A2DP profile.

Thanks for the reply it was just on the off chance as thought you might know.
