Aci_Gap_Create_Connection

Description:

Start the direct connection establishment procedure. A LE_Create_Connection call will be

made to the controller by GAP with the initiator filter policy set to “ignore whitelist and

process connectable advertising packets only for the specified device”. The procedure can

be terminated explicitly by the upper layer by issuing the command

Aci_Gap_Terminate_Gap_Procedure. When a command is issued to terminate the

procedure by upper layer, a LE_Create_Connection_Cancel call will be made to the

controller by GAP.

Description

Scan_Interval

2 bytes

Time interval from when the controller started its last LE scan

until it begins the subsequent LE scan. The scan interval should

be a number in the range 0x0004 to 0x4000. This corresponds to

a time range 2.5 msec to 10240 msec. For a number N, Time = N

* 0.625 msec.

Scan_Window

2 bytes

Amount of time for the duration of the LE scan. Scan_Window

shall be less than or equal to Scan_Interval. The scan window

should be a number in the range 0x0004 to 0x4000. This

corresponds to a time range 2.5 msec to 10240 msec. For a

number N, Time = N * 0.625 msec.

Peer_Address_Type

1 byte

0x00: Public device address (default)

0x01: Random device address

Peer_Address

6 bytes

Address of the peer device with which a connection has to be

established.

Own_Address_Type

1 byte

0x00: Public device address (default)

0x01: Random device address
