Hi I was able to get it working by changing the value of

CONFIG_NET_BUF_DATA_SIZE=2048. it was 128 initially.

Hi Arjun,

I did not get time to review your codes. We are low staff due to summer vacation period.

I just figure out Azure IoT Hub — nRF Connect SDK 2.7.99 documentation (nordicsemi.com) properly show how to configure device/client certificate for nRF7002 Wi-Fi application.

Can you learn about its usage and compare with your codes?

Best regards,

Charlie

Yes i have looked into the link that you have shared.
I am sorry i missed out to mention that i am working on an nrf7002DK/EK board. So had to depend on the link provided below for an example code for MQTT.

I had looked into the example provided in the academy link: https://academy.nordicsemi.com/courses/wi-fi-fundamentals/lessons/lesson-4-wifi-fundamentals/

but this example also shows only the implementation using CA certificate only, the TLS client certificate implementation is not provided here.

Have you looked into the code i shared?

If you comment out the implementation of client_certificate[] and priv_key[] and change the

CONFIG_MQTT_BROKER_PORT to 8883, it works fine. on adding this portion im getting the error reported

Hi Arjun,

Did you get chance to test this sample direclty MQTT — nRF Connect SDK 2.6.1 documentation (nordicsemi.com)?

Best regards,

Charlie
