This section describes the AT Command Set for a BTM module. This section is structured in functional
groups of AT commands, related to module configuration, Bluetooth profiles, hardware units and
miscellaneous purposes.
Assumptions
Command Syntax
The following syntax is employed throughout this document to describe optional or mandatory parameters for
AT commands.
General AT Commands
<bd_addr>
<devclass>
N
M
<string>
<uuid>
1. All commands are terminated by the carriage return character 0x0D, which is represented by the string
2. All responses from the BTM device have carriage return and linefeed characters preceding and
3. All Bluetooth addresses are represented by a fixed 12 digit hexadecimal string, case insensitive.
4. All Bluetooth Device Class codes are represented by a fixed 6 digit hexadecimal string, case insensitive.
5. All profile specific commands are identified by the prefix shown in Table 3.1
1. AT
2. ATEn {Enable/Disable Echo}

appending the response. These dual character sequences have the values 0x0D and 0x0A respectively
and shall be represented by the string <cr,lf>.
Used to check the module is available.
Response: <cr,lf>OK<cr,lf>
This command enables or disables the echo of characters to the screen. A valid parameter value will be
written to S Register 506.
E0 … Disable echo.
E1 … Enable echo.
All other values of n will generate an error.
Response: <cr,lf>OK<cr,lf>
Or
Response: <cr,lf>ERROR nn<cr,lf>
A 12 character Bluetooth address consisting of ASCII characters ‘0’ to ‘9’, ‘A’ to ‘F’ and ‘a’ to ‘f’.
A 6 character Bluetooth device class consisting of ASCII characters ‘0’ to ‘9’, ‘A’ to ‘F’ and ‘a’ to ‘f’.
A positive integer value.
An integer value which could be positive or negative, which can be entered as a decimal value or
in hexadecimal if preceded by the ‘$’ character. E.g. the value 1234 can also be entered as $4D2
A string delimited by double quotes. E.g. “Hello World”. The “ character MUST be supplied as delimiters.
