I have been developing with nRF51 for some time and already implemented a nice 13.56MHz wireless charging circuit. Now that I'm moving to nRF52 I would like to keep my wireless charging coil / circuit as is, but also be able to use nRF NFC functions.
So, is it possible to use the same coil for WPT and NFC? I've been considering changing the WPT frequency, but do I really need to? If anyone has experience of this challenge, or some tips the would be most appreciated
