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 exposes 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 profile when not specified
explicitly in the ATD command.
S102
Depending
on module
variant
Depending
on
supported
profiles
Defines a set of bits masks for enabling profiles.
Values can be ORed.
A profile can be enabled only if it is supported by the BTM
variant.

Boot Mode on cold boot
Boot modes are required to configure some low level device
settings which cannot be configured by S registers and AT
commands. Currently there are predefined settings defining
the PCM data format to be used with certain codec ICs
(applies mainly to BC04).1 – normal
