AT Command Interface Specification

Overall Description

commands such as the AT^XXX:<arg0>,<arg1> commands, or added to the end of the ^ symbol, colon, and comma. No redundant space is added ahead of or to the end of a command. This rule is applicable to the communication between the MT and TE programs.

3.For an uninterruptible AT command, after sending the AT command, the TE must wait until the MT responds to the AT command before sending the second AT command. Otherwise, the second AT command sent by the TE is not executed.

4.Unless otherwise stated, all default codes between the TE and MT follow the format of GSM 7 bit Default Alphabet. For details, see section 6 in the 3GPP TS 23.038 protocol. The @ character is still transmitted as 0x00 of the 7bit coding on interfaces. Therefore, the MT and TE must be able to process the character. The MT passes the carriage return character (<CR>) and line feed character (<LF>) in a string as spaces to the TE.

5.A string refers to a byte stream that is placed inside double quotation marks, excluding the quotation marks or commas.

6.A string used by the TE to send a command cannot contain the combination of quotation marks and commas (confusing a parameter with a string). The current version does not support escape character. The code value of a data format in the UCS2 coding is reported as characters. For example, if the UCS2 code of a Chinese character is 0x553a, the 553a is reported.

A possible response sent by the MT to the TE consists of Information text and Result code, in which Information text is optional and Result code is mandatory. The format of a possible response is controlled by the ATV command. For details, see the description of the ATV Command. In this document, all possible responses listed in tables follow the ATV1 format.
