I went on with another issue, and when I got back to this I was unable to recreate it. I will open a new ticket if I am able to reproduce it in the future.

Hello,

would it be possible for you to share the code?

I should add that my overlay looks like this:

&pinctrl {

uart1_default_alt: uart1_default_alt {

group1 {

psels = <NRF_PSEL(UART_TX, 0, 18)>,

<NRF_PSEL(UART_RX, 0, 17)>,

<NRF_PSEL(UART_RTS, 0, 21)>,

<NRF_PSEL(UART_CTS, 0, 19)>;

};

};

uart1_sleep_alt: uart1_sleep_alt {

group1 {

psels = <NRF_PSEL(UART_TX, 0, 18)>,

<NRF_PSEL(UART_RX, 0, 17)>,

<NRF_PSEL(UART_RTS, 0, 21)>,

<NRF_PSEL(UART_CTS, 0, 19)>;

low-power-enable;

};

};

};

&uart1 {

status = "okay";

current-speed = <115200>;

pinctrl-0 = <&uart1_default_alt>;

pinctrl-1 = <&uart1_sleep_alt>;

pinctrl-names = "default", "sleep";

};
