2.4.1 LMP Response Timeout

(pairing sequence) : fixed on spec


The time between receiving a baseband packet carrying an LMP PDU and

sending a baseband packet carrying a valid response PDU, according to the

procedure rules in Section 4 on page 249, shall be less than the LMP

Response Timeout. The value of this timeout is 30 seconds.



2.4 PAGE TIMEOUT (0x04)

(acl connection)

The Page Timeout error code indicates that a page timed out because of the

Page Timeout configuration parameter. This error code may occur only with the

Remote_Name_Request and Create_Connection commands.


Range: 0x0001 to 0xFFFF

Default: 0x2000 (8192)

Mandatory Range: 0x0016 to 0xFFFF

Time = N * 0.625 msec

Time Range: 0.625 msec to 40.9 sec

Time Default: 5.12 sec


6.7 CONNECTION ACCEPT TIMEOUT

The Connection_Accept_Timeout configuration parameter allows the BR/EDR

Controller to automatically deny a connection request after a specified time

period has occurred and the new connection is not accepted. The parameter

defines the time duration from when the BR/EDR Controller sends a

Connection Request event until the BR/EDR Controller will automatically reject

an incoming connection.


Range: 0x0001 to 0xB540

Default: 0x1F40 (8000)

Mandatory Range: 0x00A0 to 0xB540

Time = N * 0.625 msec

Time Range: 0.625 msec to 29 sec

Time Default:

BR/EDR 5 sec

AMP type dependent


6.8 PAGE SCAN INTERVAL

The Page_Scan_Interval configuration parameter defines the amount of time

between consecutive page scans. This time interval is defined from when the

Controller started its last page scan until it begins the next page scan.


Range: 0x0012 to 0x1000; only even values are valid

Default: 0x0800

Mandatory Range: 0x0012 to 0x1000

Time = N * 0.625 msec

Time Range: 11.25 msec to 2560 msec

Time Default: 1.28 sec



6.9 PAGE SCAN WINDOW

The Page_Scan_Window configuration parameter defines the amount of time

for the duration of the page scan. The Page_Scan_Window can only be less

than or equal to the Page_Scan_Interval.


Range: 0x0011 to 0x1000

Default: 0x0012

Mandatory Range: 0x0011 to Page Scan Interval

Time = N * 0.625 msec

Time Range: 10.625 msec to Page Scan Interval

Time Default: 11.25 msec


2.8 CONNECTION TIMEOUT (0x08)

(check link loss)

The Connection Timeout error code indicates that the link supervision timeout

has expired for a given connection.



6.21 LINK SUPERVISION TIMEOUT

The Link_Supervision_Timeout parameter is used by the Controller to monitor

link loss.

Range: 0x0001 to 0xFFFF

Default: 0x7D00

Mandatory Range: 0x0190 to 0xFFFF

Time = N * 0.625 msec

Time Range: 0.625 msec to 40.9 sec

Time Default:

BR/EDR 20 sec

AMP 10 sec


usually set to 0x1F40 (8000) : 5 sec



6.28 LOGICAL LINK ACCEPT TIMEOUT

The Logical_Link_Accept_Timeout configuration parameter allows the AMP

Controller to automatically deny a logical link request after a specified time period

has elapsed and the new logical link has not completed.

Range: 0x0001 to 0xB540

Default: 0x1F40

Mandatory Range: 0x00A0 to 0xB540

Time = N * 0.625 msec

Time Range: 0.625 msec to 29 sec

Time Default: AMP Type dependent : 5 sec



6.36 SYNCHRONIZATION TRAIN INTERVAL (for LE)

The Sync_Train_Interval configuration parameter defines the time between

Synchronization Train transmit events on a single transmit RF channel.

Default: 0x0080

Mandatory Range: 0x0020 to 0x1000

Time = N * 0.625 msec

Time Range: 20 msec to 40.9 sec

Time Default: 80 msec


6.37 SYNCHRONIZATION TRAIN TIMEOUT (for LE)

The synchronization_trainTO configuration parameter is used by the controller

to terminate the Synchronization Train after it has been started via the

HC_Start_Synchronization_Train command.

Default: 0x0002EE00

Mandatory Range: 0x00000002 to 0x07FFFFFE

Time = N * 0.625 msec

Time Range: 1.25 msec to 23.3 hours

Time Default: 120 msec


6.2 INQUIRY SCAN INTERVAL

The Inquiry_Scan_Interval configuration parameter defines the amount of time

between consecutive inquiry scans. This is defined as the time interval from

when the BR/EDR Controller started its last inquiry scan until it begins the next

inquiry scan.

Range: 0x0012 to 0x1000; only even values are valid

Default: 0x1000

Mandatory Range: 0x0012 to 0x1000

Time = N * 0.625 msec

Time Range: 11.25 to 2560 msec

Time Default: 2.56 sec

usually try 2 times = 5.12 sec
