lwip_mqtt_enet_qos_freertos
Overview
The lwip_mqtt demo application demonstrates MQTT client connecting to MQTT broker via unsecured socket. The application obtains IP and DNS addresses from DHCP and resolves broker’s hostname if needed. Then it connects to the broker and subscribes to the “lwip_topic/#” and “lwip_other/#” topics. Further it publishes five messages to the “lwip_topic/100” which are also received back as the board is subscribed to the “lwip_topic/#”. Meanwhile it continues to receive messages published to the subscribed topics from other clients.
