Can multiple commands be concatenated together on the same line?The commands such as E0, V1,&D0, etc., can be added together, (i.e. ATE0V1&D0).
If you want to add the commands such as the + commands, you will have to separate the commands with a semi-colon, (i.e. AT+CSQ;+CREG?).
You can't use the IP, # commands together in one string.
