No problem to use "old" no.

[quote user="kme"]So there are various UART drivers and libraries in the nRF SDK, e.g. app_uart ("old" lib), libuarte ("new" lib), nrf_drv_uart ("old" driver) and nrfx_uarte ("new" driver).[/quote]

So these "old" parts are not obsolete? It can still be used?

Hi,

So there are various UART drivers and libraries in the nRF SDK, e.g. app_uart ("old" lib), libuarte ("new" lib), nrf_drv_uart ("old" driver) and nrfx_uarte ("new" driver).

They provide different abstraction and functionality of using the UART peripheral in an application.

In general the nrfx* is the low level driver that give you full control over the peripheral, while the app*/lib* library give you more high level api where you don't need to think about the low level hardware registers.

Which to use depends on your requirements, if you find that the app*/lib* provide the functionality you need then there is no need to use the nrfx* driver.
