I didn’t bother, based on what @johan-bjareholt wrote:
Oh, that’s very disappointing. I drive a lot and Bluetooth is a high-priority use case. Internal speaker and mic in the car are horrible. I’ll have to find the thread with the link to the “put your money where your mouth is” campaign and start funding an HFP/HSP effort. Seems like it would be important to Linux in general, but I can’t see mobile Linux taken seriously without it.
Being able to make handsfree calls in your car via bluetooth has been bog standard for years over here in Europe. Considering our traffic laws, it is pretty esential.
Hope Purism remedies this soon.
I have a Genki Bluetooth adapter that I use for my Nintendo Switch. While not a solution, I wonder if it would work in the USB-C port on the Librem 5. I’m curious if the car would be able to connect to the Genki. Something I’ve never tried.
A bluetooth connection (mic, speakers, and address book) with a car is só basic, that it should work ‘out of the box’ without the need for any periferals.
