AT Commands Interface Guide
Protocol Specific Commands
11.6. Parameter Format of AT Commands
Double quotation marks are optional in the parameter input of protocol specific AT commands.
If the AT command does not meet the following conditions, the AT parser will regard it as an error and
will not go to the corresponding AT command handler. It will immediately return +CME ERROR: 3.
This means that it will not process any action further or return any specific error code.
If double quotation marks are used to enclose parameters, double quotation marks must
appear at both the head and tail of the parameter.
The total number of parameter input (including empty parameters) in the AT commands must
be within the minimum and maximum required number of parameters.
