NFMI - FULL DUPLEX AUDIO ?

RF-DEVELOPER — Sun, 31 Oct 2021 17:02:00 GMT

Hello dear NXPeople !

I have a few questions i can't abstract from the datasheets.

1. I see the NFMI devices are called 'transceivers'. But is it possible to create a FULL-DUPLEX audio link with it ?

2. if not possible, then, use an UPLINK / DOWNLINK with 4 devices at 2 frequencies ?? Seems a bulky solution to me

3. How many devices can operate in the same magnetic bubble ?

4. General Question: Does the latest BT LE 5.2 make the usage of NFMI unneccessary ? For linking earbuds I mean. Because, the latest 5.2 has such a better error-correction, better handling of multi-path / antenna-null caused errors and also a more compact, efficient protocol.

We don't really understand why everything is so hard to access nowadays ? If for questions like this, a sales representative needs to be contacted, what is the purpose of this NXP-community ? We earned dozens of useless badges, but never found 1 useful answer to NFMI questions. Remarkable.
