Description
Page Scan Interval in units of msec
Page Scan Window in units of msec
RFCOMM frame size for all RFCOMM based profiles.
23-512 range has a granularity of 1; 512 to 4096 range has
a granularity of 4.
For example: Setting 4095 sets a value of 4092 (round down
new values).
Note: Testing and calculations by our stack vendor show
that the incremental benefit above 990 is not worth
the downside of handling larger payloads.
Link supervision Timeout in seconds.
This value only reads on power up when the profiles are
registers. After changing the value it needs committing to
non-volatile memory using AT&W or CMD_SREG_STORE
and then the module needs a power cycle.
Auto Accept Channel Setup. If this is 1, incoming
connections automatically accept.
If this is 1, EVT_CONNECTION_SETUP events are not sent to
the host when an incoming connection arrives.
Master/Slave role preference for SPP incoming connections.
0 = Don’t Care
1 = Prefer Master
2 = Prefer Slave
3 = Must be Master
4 = Must be Slave
Master/Slave role preference for SPP outgoing connections.
0 = Don’t Care
1 = Prefer Master
2 = Prefer Slave
3 = Must be Master
4 = Must be Slave
If Profiles Reg 3 bit 0 is set and this is not 0, then incoming
SPP connections are allowed up to the number specified in
this register.
If Profiles Reg 3 bit 0 is set and this is not 0, then outgoing
SPP connections are allowed up to the number specified in
this register
Enable DeviceID SDP record, and use the vid/pid as per
registers 37 and 38.
USB Vendor ID to use in the DeviceID record
