I read somewhere for new project we should use nrfx driver because in future old nrf_drivers will not be support and improve. All examples in sdk15.3 as I understand used old nrf_drv..... Can I guess I used new abilities of new nrfx driver just replace
1. nrf_drv.... to nrfx.....
2. add to project existing file from nRF5_SDK_15.3.0_59ac345\modules\nrfx\drivers\src\..... needed nrfx drivers
3. turn according nrfx driver in sdk_config.
or I need do something else (other)
Maybe there's clear manual how to transfer to the new nrfx world
