Paho MQTT Client example with W7500

You have to change

You have to use your ethernet(network) information.


    uint8_t mac_addr[6] = {0x00, 0x08, 0xDC, 0x00, 0x00, 0x00}; // your mac address
    const char * ip_addr = "???.???.???.???"; // your ip
    const char * gw_addr = "???.???.???.???"; // your gateway
    const char * snmask = "???.???.???.???"; // your subnetmask

And you have to use your mqtt broker server information. Broker server ip address and port number listed bleow are available now. But I will close the mqtt broker server on July 15,2015.


    char* hostname = "";
    int port = 1883;
