charactersareignoredonthecommandlineandmaybeusedfreelyforformattingpurposes,unlesstheyare

thesameastypingAT+COPS=1,0,A1;typingAT+COPS=1,0,"ABB"isdifferentfromtypingAT+COPS=1,0,ABB.

Astringisalwayscasesensitive.

Somecommandsrequireyoutoalwaysplacetheinputstringparameterswithin

quotes.Whenthisisrequired,the

commanddescriptionsexplicitlytellyouso.

CommandLines

Acommandlineismadeupofthreeelements:theprefix,thebodyandtheterminationcharacter.

Thecommandline prefixconsistsofthecharacters“AT”or“at”.Torepeattheexecutionoftheprevious

commandline,usethecharacters“A/”or“a/”orAT#/orat#/.

UsingparameterS3,you

canselecttheterminationcharacter.Thedefaultis<CR>.

Thestructuresofthecommandlineare:

 ATCMD1<CR>whereATisthecommandlineprefix,CMD1isthebodyofabasiccommandand<CR>isthe

commandlineterminatorcharacter.

Thenameofthecommandneverbeginswiththecharacter“+”

 ATCMD2=10<CR>where10isasubparameter.

 AT+CMD1;+CMD2=,,10<CR>Thesearetwoexamples ofextendedcommandsTheyaredelimitedwith

semicolon.Inthesecondcommandthesubparameterisomitted.

Thenameofthecommandalwaysbeginswiththecharacter“+”.
