General S Registers
The following table lists all general S Registers. Please not that this is not a complete listing of S Registers.
Additional S registers, associated with a certain prole or feature are described in the appropriate section above.
Register Det. Range Description
S2 94 32..126 Escape sequence character. It is not ‘+’ by default as a Bluetooth®
serial link can be used to connect to a mobile phone which ex-
poses an AT command set, which will in turn use ‘+’ as default. So
if both used ‘+’ there will be confusion. 0x5e is the character ‘^’.
S12 100 40..5000 Escape sequence guard time in milliseconds, with a granularity of
20ms. New values are rounded down to the nearest 20ms multiple
S101 $1101 $0..$ffff UUID of default SPP based prole when not specied explicitly in
the ATD command.
S102 Depending
on module
variant
Depending
on supported
proles
Denes a set of bits masks for enabling proles. Values can be
ORed.
A prole can be enabled only if it is supported by the BTM variant.
Issue AT&W and ATZ in order to make the new setting effective.
0x001 is Serial Port Prole
0x002 is Headset (“HS”)
0x004 is DUN
0x008 is Audio Gateway (Headset, ”HSG”)
0x010 is Handsfree (“HF”)
0x020 is OBEX FTP
0x040 is Audio Gateway (Handsfree, “HFG”)
0x080 is A2DP
0x100 is AVRCP
0x200 is PBAP
0x400 is HID
S103 1 1..4 Boot Mode on cold boot
Boot modes are required to congure some low level device
settings which cannot be congured by S registers and AT com-
mands. Currently there are predened settings dening the PCM
data format to be used with certain codec ICs (applies mainly to
BC04).
1 – normal
2..4 – for future customization of the module
S325 1 0..1 Store link key automatically on dedicated bonding outgoing (DBO)
S326 1 0..1 Store link key automatically on general bonding outgoing (GBO)
S327 1 0..1 Store link key automatically on dedicated bonding incoming (DBI)
S328 1 0..1 Store link key automatically on general bonding incoming (GBI)
S329 0 0..1 Enable legacy (BISM2) response format
S330 1 1..31 Congure 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
CONNECT message, separated by a comma
applies only to role indicating UUID (e.g.HSP/HFP) and if S329=0
