Good morning Thomas,

thanks for the detailed list!

I'm looking at the FM radio features the different chipsets support and
what a common API could look like. The Qt Radio interfaces are a good
start, but e.g. this morning I noticed that at least the MediaTek
chipsets also seem to have some support for FM transmit. No idea if this
actually works though, and if e.g. bq made sure the audio output is
connected to the FM transmitter.

Ah, thanks for the pointer. I have a bit of test code for the MediaTek
chipset in the Aquaris E4.5 to see if things work at all, if they work
it was my plan to do any future work against the proper platform bits.

I fully agree. Let's see what we can come up with.

cheers,
