Change NUS UART to P0.00 P0.01

[Quocanhdeptrai_ReturnTrue]

Hi all,

I am using project v3.1.1\nrf\samples\bluetooth\peripheral_uart\

How can I change nus uart to Pin P0.00 P0.01.

Thank all for support.

Hi,

In the peripheral_uart sample on nRF54L15, the NUS service is bound to uart20. The uart20 peripheral (UARTE20) can only be mapped to GPIO port P1 (or dedicated P2 pins) as documented here. However we can see its mentioned that UARTE30 supports GPIO port P0 so on a custom nRF54L15 board you can route uart30 to P0.00 / P0.01 and use that UART for NUS (by setting nordic,nus-uart = &uart30 and configuring pinctrl accordingly in the overlay).

But on the nRF54L15 DKusing P0.00 / P0.01 for uart30 is still not supported in practice because those pins are already hard‑wired to the debugger’s UART_0. I hope it helps.
