Setting nrf700x-coex ble-WiFi brings error

[sguitton01]

Hi All,

I am trying to add the BLE Wifi Coexistence on the nrf7002DK to my project by following this.
I am simply adding this to the overlay

/ {

    nrf_radio_coex: nrf7002-coex {

       status = "okay";

       compatible = "nordic,nrf700x-coex";

       req-gpios =     <&gpio0 24 (GPIO_ACTIVE_HIGH)>;

       status0-gpios = <&gpio0 14 (GPIO_ACTIVE_HIGH)>;

       grant-gpios =   <&gpio0 25 (GPIO_ACTIVE_HIGH | GPIO_PULL_UP)>;

 };

};

and this to prj.conf : 

CONFIG_MPSL_CX=y

CONFIG_MPSL_CX_NRF700X=y

As soon as I am doing this two changes some errors appear, here's the logs :

Do you know why? What am I doing wrong?

Thank you,

Hi Sylvain

Okay, but I don't see that you've also done step 4 where you need to apply the same devicetree nodes to the network core as well as the application core. Can you please confirm you've done that as well?

Best regards,

Simon

Hi Simon, I think that's it, thank you,
