2.1.3 AT Command syntax

Commands always start with the AT (short for attention) characters and ends with a <CR>

(<Enter> key) character.

Commands may be entered in upper or lower cases.

Command names may use letters, digits and punctuation characters (+, &, \, …).

BlueTree specific AT commands start with +B. All other listed commands are either third party

commands or industry de-facto standard commands supported by BlueTree modems. Non-listed

commands are not supported and return the ERROR string.

The specific syntax of each supported AT command is given in the description of the command in

the subsequent sections of this document.

In general the syntax of the AT commands follows the following rules:

 Command with no parameter:

AT<command_name>

 Command with parameters:

AT<command_name>=<parameter1>[,<parameter2>[…]]

 Query the actual setting parameters of a command:

AT<command_name>?

 Query the syntax of a command:
