The above commands are not interpreted by DLBM-CG121 and rely on the mobile phone to
respond to these messages. All responses are passed directly to the hands free kit.
All other operation relating to service level connection and Bluetooth operation is handled by
DLBM-CG121
. In handset mode, some of these commands will be passed to the phone host for
interpretation such as AT+BVRA = <n> for voice recognition activation and AT+NREC=<n> for
noise cancellation request.
13.13.1 Bluetooth Hands Free Profile
The Bluetooth Hands Free profile is a mixture of analogue and data services. On connection of
a Hands Free kit to the phone, the mode state will be Audio. Therefore a phone not supporting
audio and data services simultaneously will not be able to support Bluetooth Hands free
operation.
The majority of commands used by the Hands Free profile are based on the GSM07.07 AT
command set. For all these commands,
DLBM-CG121
firmware will simply act as a feed through
for the commands and responses. Therefore, commands such as CMER, CIND, ATA,
AT+CHUP, ATD etc are not issued by
DLBM-CG121
but by the Hands Free kit.
It is still possible, however, to add more functionality to the Bluetooth hands free profile by
emulating some of the Bluetooth commands into a mode that the phone supports, e.g.
AT+BVRA=1 would initiate a voice tag dial in a Bluetooth phone.
In order to set up the supported features list to be sent with the SDP record, PSKEY_USR7
stores the Supported Features list in the same order as expected by the Hands Free Profile i.e.
