AT COMMAND SET
REFERENCE APPENDIX
Register Deflt. Range Description
S330 1 1..31 Configure inquiry response of AT+BTI (Bitmask):
1 - show device address
2 - show class of device
4 - show friendly name
8 - show extended inquiry data
Values can be ORed
S331 2 0..2 Direction indication style for “CONNECT” messages
0 – disabled
1 – character style: append ‘I’ to incoming and ‘O’ to outgoing
CONNECT message, separated by a comma
2 – symbol style: append ‘<’ to incoming and ‘>’ to outgoing

S329=0
S334 0 0..1 Enable Extended Sdp Error Codes
0 - disable
1 – enable
S504 0 0..1 Enable silent operation:
Setting to 1 will force S0 to -1 and will suppress messages
arising from connections or pairing. E.g. CONNECT, NO
CARRIER, RING, PAIR etc.
Suppressing connection based messaged allows the device to
be configured in cable replacement mode
S505 10 2..120 Minimum delay before abandoning connection
attempt as a master.
Referenced by ATD. In units of seconds. See S Registers 530
and 543 also. Please note that as disconnection time can vary,
this register only guarantees the minimum delay. Note that
for invalid addresses specified in the ATD command, the “NO
CARRIER” response will be immediate. See S register 560 for
specifying disconnect max timeout
S506 0 0..1 Enable/Disable echoes. The ATEn command also affects this.
S507 0 0..2 When set to 0, a connection can be dropped using ^^^ escape
sequence only and the state of DSR line is ignored.
When set to 1 a connection can be dropped using EITHER the
^^^ escape sequence OR the DSR handshaking line. When set
to 2, a connection can only dropped using a deassertion of
DSR. Mode 2 provides for the highest data transfer rate.
If the status of the DSR line is to be conveyed to the remote
device as a low bandwidth signal then this register MUST be
set to 0, otherwise a deassertion of DSR will be seen as a
request to drop the Bluetooth® connection. This register
affects S Register 536 – see details of 536
