3.4 Unsolicited Responses
The ‘AT’ Protocol is a command/response type of protocol. This means that the Laird Technologies device will
normally only respond to AT commands.
Under special circumstances, unsolicited responses will be sent to the host. They are described in the
following subsections.
3.4.1 RING
This string is sent to the host when a remote device is initiating a serial port connection. The fully qualified
string is in the form RING 012345678901 where 012345678901 is a 12 digit hexadecimal number which
corresponds to the remote device’s Bluetooth address. This response is sent to the host every 2 seconds until
the host either accepts the connection using the ATA command or rejects it using the ATH command.
3.4.2 PIN?
This response is sent to the host during a pairing negotiation.
The fully qualified string is PIN? 012345678901 where 012345678901 is the Bluetooth address of the peer
device. In response, the host must supply a pin code which is entered using the AT+BTK command.
If the peer address does not supply the address in the message exchange, then the address is specified as
000000000000 – and the paring will proceed as normal.
3.4.3 AUDIO ON
This response is sent to the host when a SCO channel has been established.
3.4.4 AUDIO OFF
This response is sent to the host when an existing SCO channel has been closed.
3.4.5 AUDIO FAIL
This response is sent to the host when a SCO channel setup fails.
3.4.6 ERROR 27
This response is sent to the host on power up if the firmware is unlicensed.
