 Texts sent as part of the message are delimited with double quotation marks. In C++ we need to mark them with backslash characters inside the string constants. Examples above include these markings. Texts sent as part of the message are delimited with double quotation marks. In C++ we need to mark them with backslash characters inside the string constants.

 +Some explanation can be needed for the "AT+RST" and "AT+SYSSTORE=0" commands. 
 +If we don't use the "AT+SYSSTORE=0" command our module stores the WiFi credentials in non-volatile memory and automatically connects to the network after powering on. In our laboratory, it is not recommended because the next commands can return "ERROR" if we try to connect the network and MQTT broker if we are already connected.
 +If we don't use the "AT+RST" command our module will keep the WiFi connection active, even if we upload the new version of the software. It would result in the same error in the case of WiFi or MQTT reconnecting.

 +Because LCD can't properly display some non-visible characters the presented code sometimes shows additional, non-letter characters. It is out of the scope of this scenario to filter these characters out. We leave the task of making visual improvements to your invention.
