Hi Vasu,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
To provide the fastest possible support, I'd highly recommend you refer to the mbedtls_examples in the SDK library for details.

Have a great day,
TIC

Hi jeremyzhou‌,

        Thank you for your reply.

        I have already refereed evkmimxrt1060_lwip_httpscli_mbedTLS_freertos code it was working fine.

        But we used evkmimxrt1064_lwip_mqtt_freertos example code for our project.

        evkmimxrt1064_lwip_mqtt_freertos this mqtt library supports TLS ?

        Otherwise i have to start own mqtt stack TCP + MQTT + TLS ?

Thanks & Regards,

     Vasu

Hi Vasu,

Thanks for your reply.
1) evkmimxrt1064_lwip_mqtt_freertos this MQTT library supports TLS ?
-- Yes, and the tutorial: Tutorial: Secure TLS Communication with MQTT using mbedTLS on top of lwip | MCU on Eclipse shows how to implement Secure TLS communication via using mbedTLS, please refer to it for details.

Have a great day,

Hi jeremyzhou‌,

       Sorry for the late reply,

       This code based on raw api but we are using freertos.

        Any freertos based example code is available ?

Thanks & Regards,

        Vasu

Hi Vasu,

Thanks for your reply.
1) Any Freertos based example code is available?
-- Unfortunately, there's no similar demo code.

Hi jeremyzhou‌,

As suggested, we implemented the TLS in our application. Still we are unable to connect to broker with certificate.

once after handshake, its reading protocol version as SSL 3.0. 

Can somebody help on solving this, if required we will share the workspace or wire shark packet.

Thanks & Regards,

 Vasu
