Would a Bluetooth dialer work with the Librem 5?

Hardware Librem 5

I thought I may use a Bluetooth dialer like one of those listet on the page below. That could be practical while on the go. The worthy Librem 5 could stay in a safer place like my messenger bag. I don\t have to pull it out and avoid the risk of dropping it.

I could use Bluetooth in ears. Unfortunately these are tricky to use, because most of them are controlled by touch surfaces nowadays which are also often bounjjjd to multiple functions. When the phone rings it might very well be, that I hurry to pull them out, put them into my ears and answering the call without accepting the incoming call to early or cancel it entirely by accident.

I think this is possibly easier with a mini-phone-like device.

I think chances that it works are not that bad for incoming calls, but what about outgoing calls? Those devices have a contacts function and keys for entering phone numbers. They can also be used as GSM phones. I don’t know if the contacts function and the numeric keys can be used to choose a contact from the Librem 5 or make the Librem 5 dial a number that I type on the dialer device.

Not sure on which levels both devices have to cooperate. Bluetooth obviously. I guess the calls and contacts apps. Some dialers can sync contacts. Not sure if both devices couple like a keyboard- like input device. Audio must be streamed. Sounds complex alltogether.

Synching contacts over Bluetooth should be possible but I have no idea whether this works on the Librem 5 yet.

However would you want that? Isn’t this undermining the reason to have a Librem 5?

If you hand over all your contacts to a blackbox device that contains a SIM … is that a good idea?

If you hand over the content and metadata for all your calls to a blackbox device … is that a good idea?

We have the touchscreen technology, can we put a rotary dial on a phone?

It would be just like swiping other responses, only in a circular mostion.

Half the people here won’t know what you’re talking about…lol. How about party lines too?

I’m pretty sure that BTHFA does not work on the L5 yet. Because of the poor audio on the phone itself I’m dying for this to become a reality, I’m not sure what the hold up is.

Oh, and not only rotary dial, but the click, click, click sound of the rotary brushes coming over the line.

I would miss the tactile feeling of your finger hitting the finger stop. I guess you could epoxy one to the glass somehow?

Well there was quite some number of rotary phones going through my hands after they got replaced. They where not interestingly old like those being made of Bakelite or so. But still they where sometimes decades older than me and hell where those devices robust! Built to survive a bombardment. And there were dead simple foolproof.

And the sounds while dialing came from pulse dialing replays switching in the main distributor building. Now most rooms there are empty. And the job of all the relays is done by computers inside a little rack.

I tried to use two different Bluetooth headphones. None of them could accept an incoming call. So at least it looks like the hands-free profile is not implemented completely or correctly for this task out of the box. I haven’t read all related threads in the forum, yet and did not deep dive otherwise. However the transition from pulse-audio to pipewire is delayed.

What about an headset with cable and buttons? I don’t have any to try. Would such a headset work with Librem 5 to accept calls?

I remember the earphones included with the Librem 5 has an in-built microphone you can use for calling.
