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

With that version of the DK NCS 2.5.0 should by default build for that chip revision, so that shouldn't be the issue. Can you send a (high-res) picture of your DK, and some information on how you're posing it and what the switches on the DK is set to?

The error messages you get is telling you that you're not able to communicate correctly with the nRF7002 chip for some reason, so I just want to see that the DK seems to be correctly set up.

Best regards,

Simon
