Reference AT Commands

The following AT commands can be entered via a command interface and used to

configure the WSA.

Some AT commands contain information in angle brackets, e.g.

<hex>

<Name>

that have to be replaced by the respective parameters.

This command is concluded with the character for “carriage return”. This character is

0x0d, or decimal 13 from the ASCII code. This character is automatically sent, for

example, when using the HyperTerminal software by pressing Enter.

8.1

The command

is used for checking the link to the WSA. If the connection is

successful, the WSA returns the

00 SUCCESS

message.

8.2

Group “AT BTID”: Identifiers

Commands starting with “AT BTID” involve identifiers of the WSA, e.g. the

device name, the

Bluetooth

MAC ID and the CoD, which can be read by other

devices.

8.2.1

AT BTID ?

The

AT BTID ?

command queries the

Bluetooth

MAC ID and device name.

8.2.2

AT BTID ADR ?

The

AT BTID ADR ?

command queries the

Bluetooth

MAC ID of the WSA.

In the command output,

BDADR

is used for the MAC ID if necessary.

8.2.3

AT BTID COD

This command queries (

AT BTID COD ?

) or modifies

(

AT BTID COD = <hex>

) the CoD of the WSA as a hexadecimal value.

The CoD is a 32-bit field specifying the capabilities and functionality of a

Bluetooth

device and is sent with the packet “Frequency Hop Synchronization”

(FHS) during device discovery.

The CoD allows rapid classification of remote devices in various device

categories such as Network, Audio or Telephony.

In the current version of

Bluetooth

standards, the 32-bit field of the CoD contains

24 relevant bit positions. From these 24 bits, again 6 bits (the “Minor Device

Class”) are settable with the AT command

AT BTID COD

Example:

AT BTID COD = 1f04
