+===== Normal mode =====
+Normal mode is the mode in which a device executes a user program. A prerequisite for normal operation is the running of WiFi and
+MQTT server connection. If the connection can not be made, the device will be started in setup mode.
+In this case, you should check the device settings (usernames, passwords, ...) and make sure that
+network connection and server are working.
+==== Data exchange with the server====
+The data exchange with the server takes place through the MQTT protocol. The MQTT protocol uses publish-
+subscribe pattern (https://en.wikipedia.org/wiki/Publish-subscribe_pattern) where the messages to be transmitted
+(data) is organized by theme. The IoT framework has been tested on Mosquitto (http://mosquitto.org/)
+server, but you can use another server or service that follows the MQTT protocol (for example:
+Amazon AWS IoT, Azure IoT).
+==== MQTT items ====
+The IoT Framework defines some of the default themes used to track and track the device
+remote management. If necessary, the user can create a thread as needed. Subject name
+The name of the device is used for compilation. The device name is a unique name assigned by the user, which is
+prefix device themes. For example, if the device name is "dev1", then the device's themes would be
+"Dev1 / log", "dev1 / cfg", ... To achieve a better logical organization, devices should be distributed.
+sub themes, to add a device to a sub theme, the name of the device must be named as the device containing the name
+sub-topic For example, if you want to add "dev1" to the "itt / devices" subteme, the device should be
+to name it "itt / devices / dev1"
