 Some explanation can be needed for the "AT+RST" and "AT+SYSSTORE=0" commands.  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 command "AT+CWJAP..." returns "ERROR" if we try to connect the network if we are already connected. +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.

 +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.
