Looks Good
loaded the ESP_WiFiSwitch.ino into Arduino IDE and compiled it.
Error Line53 PubSubClienr mqttClient;
"no matching function for call to 'PubSubClient::PubSubCient()'

This looks what I am trying to achieve. I require ESP to connect to MQTT server where I can change the IP address depending on which network I am on. Changing the IP with a web browser is just what I require.
Do I need to use any other ino or just ESP_WiFiSwitch.ino or is there somthing else I am missing

I am running Arduino IDE 1.6.4 with ESP upgrades on Linux Ubuntu
Many Thanks

are you sure you are using this pubsubClient library version https://github.com/vicatcu/pubsubclient ?

Replaced PubSubClient and got further but now still can't compile.

line116 if (!MDNS.begin((char*) FQDN.c_str())) {
error - MDNS not declared in this scope

I wonder if I have missed something or got things wrong

In the IDE got 5 tabs
ESP_WiFiSwitch
EEPROM
MQTT
WebServer
WiFi

I have the corrisponding ino's one in each tab
This this correct or have I missed something

Many Thanks

- Fri Nov 06, 2015 5:20 am #33239 Yes that is correct so far but the error is strange...
since there is #include <ESP8266mDNS.h> in the main ino file.

Can you try the ESP8266mDNS\mDNS_Web_Server example? As I can see I have used it in the same way.
