From the guide I only changed the MQTT broker to broker.hivemq.com. Makes sure you have provisioned your board using nRF WiFI Provisioner. Every time you program the board you need to unpair the board at your smartphone Bluetooth settings.

You need to see the serial terminal logs at VS Studio Code to know what is going on with your board.

Also at MQTT Dashboard make sure you do not reverse the topics.

mtrobregado I've had great progress, but I still can't blink the LED on the nRF7002DK (the only thing I want) by commanding LED1ON on my cell phone (MQTT Dashboard) and on my PC (MQTT Explorer and MQTTX).

I put devacademy/subscribe/topic44, etc... on my cell phone and PC. Messages are only sent between the devices themselves. I.e. When I send LED1ON on the PC it doesn't appear on the cell phone and vice versa, much less does LED1 light up on the nRF7002DK.

I also inform you that I used the website below to install protobuf (on Ventura and w11) and that the nrf wifi provisioner app seems to have provisioned Ok

Change the MQTT broker to broker.hivemq.com at proj.conf.

Just an update with this. This only worked once for me. From the logs I can see the nRF7002DK connects to MQTT broker. But the messages are not being received. I will just create a new post regarding this.

Never mind it worked after flashing the hex file using the programmer tool.
