Hi @GanesanGuru,
The websocket client is already in Azure RTOS NetxDuo repository, and can be accessed through below link:
https://github.com/azure-rtos/netxduo/tree/master/addons/websocket
So far, in NetxDuo, the websocket client has been utilized by the mqtt client (access through https://github.com/azure-rtos/netxduo/blob/master/addons/mqtt/nxd_mqtt_client.c) in order to realize mqtt over websocket application. You may reference how the API functions of websocket client are called and used in mqtt client. Searching the macro "NXD_MQTT_OVER_WEBSOCKET" may bring some help.
Best Regards,
Haiqing Zhao
