Moving from UART FIFO to two separate UART instances

Do you get this from the unmodified example? Or did you integrate it into your own application?

I'm not able to reproduce this error.

Which SDK version and compiler are you using? Can you upload your sdk_config.h file?

In libuarte example i am getting following error for line

NRF_LIBUARTE_ASYNC_DEFINE(libuarte, 0, 0, 0,NRF_LIBUARTE_PERIPHERAL_NOT_USED,255,3);

: error: #94: the size of an array must be greater than zero. This is somehow related to sdkconfig file but not able to figure out what I am missing.

Hi,

The Libuarte - advanced UARTE driver library supports multiple UART instances. You can have a look at this example if you want to run both instances through libUARTE. You may also continue using app_uart for one UART instance, and use libUARTE for the second instance if you prefer that.

Another alternative is to use the UART driver directly.

Best regards,
Jørgen
