Preliminary
DLBM-CG121
On disconnection of the RFComm link, the mode state hardware output will change to the
default mode and issue the data stored in PSKEY_USR30
To ensure that the mobile phone does indeed disconnect on the loss of an RFComm link,
PSKEY_USR36 can be used to store the text string that will unconditionally disconnect the
phone from the network (e.g +++ATH\r). An alternative method is to use the DATA_SEL I/O
which will invert state for a period of 1s after the RFComm link has been lost. This can be used
to simulate disconnection of a data service.
For the list of DUN and FAX commands, refer to DUN and FAX profile specification from the
Bluetooth SIG.
13.10 Changing the default states of BlueCore2/3-Gateway
It is possible to change the default states to the following:
Make DLBM-CG121 idle. This is accomplished by sending the AT+CCNR command. This will
cancel the last operation and switch off the BlueCore radio.
Make DLBM-CG121 discoverable. This is accomplished by sending the AT+CDIS= <use
authentication> command to BlueCore. This will set-up a page and inquiry scan process so that
the device is discoverable and connectable to other Bluetooth devices. This has the
disadvantage of increasing the power consumption of DLBM-CG121. If Use Authentication is
set then the DLBM-CG121 will request a PIN on first connection to the remote device.
Make DLBM-CG121 connectable. This is accomplished by sending the AT+CCSR=<use
authentication> command to device. This will set-up a page scan process only so that the
device is only connectable to other Bluetooth devices which know it’s address already. If Use
Authentication is set then the firmware will request a PIN on first connection to the remote
device.
