Hi! I'm using the nRF9160 DK where I am aiming to send over bluetooth device count that was picked up from the nRF52840 on board to the nrf9160 on board via UART. However, I think I am having some issue with the pins. The following is in my nrf9160dk_nrf9160_ns.overlay, but I don't know if I am wiring my pins over UART correctly. What I am doing right now is wiring P0.17 to P0.06 and P0.18 to P0.08. Is this correct?
&uart2 {
current-speed = <1000000>;
status = "okay";
/delete-property/ hw-flow-control;
pinctrl-0 = <&uart2_default_alt>;
pinctrl-1 = <&uart2_sleep_alt>;
pinctrl-names = "default", "sleep";
lpuart: nrf-sw-lpuart {
compatible = "nordic,nrf-sw-lpuart";
status = "okay";
req-pin = <21>; /* <&interface_to_nrf52840 3 0>; */
rdy-pin = <19>; /* <&interface_to_nrf52840 2 0>; */
};
};
&pinctrl {
uart2_default_alt: uart2_default_alt {
group1 {
psels = <NRF_PSEL(UART_TX, 0, 18)>,
<NRF_PSEL(UART_RX, 0, 17)>;
};
};
uart2_sleep_alt: uart2_sleep_alt {
group1 {
psels = <NRF_PSEL(UART_TX, 0, 18)>,
<NRF_PSEL(UART_RX, 0, 17)>;
low-power-enable;
};
};
};
