AT Command Syntax Table 2: AT Command Syntax Multiple commands can be placed on a single line using a semi-colon (“;”) between commands. Only the first command should have AT prefix. Commands can be in upper or lower case. When entering AT commands spaces are ignored except in the following cases: ⚫ Within quoted strings, where they are preserved; ⚫ Within an unquoted string or numeric parameter; ⚫ Within an IP address; ⚫ Within the AT command name up to and including a ‘=’, ‘?’ or ‘=?’. They can be used to make the input more human-readable. On input, at least a carriage return is required. A newline character is ignored so it is permissible to use carriage return/line feed pairs on the input. Test Command AT+=? Check possible sub-parameter values Read Command AT+? Check current sub-parameter values Write Command AT+=p1[,p2[,p3[.....]]] Write command Execution Command AT+
