That seems to be a bug in the Mesh SDK.

MartinBL But this doesn't work. Check this issue https://devzone.nordicsemi.com/f/nordic-q-a/39114/uart-does-not-work-on-port-1

That's a good point. You can use the macro NRF_GPIO_PIN_MAP(port, pin) when you assign the pin numbers. So if you want to use the pins on port 1 you could do:

#define RX_PIN_NUMBER  NRF_GPIO_PIN_MAP(1, 8)
#define TX_PIN_NUMBER  NRF_GPIO_PIN_MAP(1, 6)
#define CTS_PIN_NUMBER NRF_GPIO_PIN_MAP(1, 7)
#define RTS_PIN_NUMBER NRF_GPIO_PIN_MAP(1, 5)

Hi, that's what confused me, in code it says:

define RX_PIN_NUMBER 8 define TX_PIN_NUMBER 6 define CTS_PIN_NUMBER 7 define RTS_PIN_NUMBER 5

The port is not defined there.

Hi,

Not sure if I understand your question. In the pin assignment list you can compare the pin names and numbers. if you want to use e.g. P0.08 for RxD, then tell the UART to use pin 8 (and port 0).
