Re: Nordic nRF52832 - UART redefining the pins?

Hi there,


The default PINs are configured in the board .dts file:


You can indeed change them in you .overlay file.


Hardware flow-control is not required but highly recommended.

Subject: [Zephyr-devel] Nordic nRF52832 - UART redefining the pins?


Hi Zephyr community,


So far I couldn't see where the default UART rx/tx pin mapping (RX = 8 and TX = 6) is happening in the Zephyr code.

I want to run the hci_uart on the nRF52832 SoC to implement just the BLE connectivity.


I'm wondering can the default UART pinning of RX/TX/CTS/.. be re-programmed in the nrf52_pca10040.overlay file.


E.g something like this:



Probably HW flow control is "always" required for h4 communication?!


Thanks in advance,


Best regards,
