Detailed Description

Data Types for Logical Link Control and Adaptation Layer Protocol (L2CAP).

Macro Definition Documentation

#define L2C_INVALID_PSM

(

psm

)

(((psm) & 0x0101) != 0x0001)

Validity check for PSM. PSM values must be odd. Also, all PSM values must be assigned such that the least significant bit of the most sigificant octet equals zero.

#define L2CAP_BLE_COC_SDU_OFFSET   4

to provide upper layer some minimal offset possibly required to process incoming packets

#define L2CAP_BLE_CONN_MIN_OFFSET   9

HCI type(1), len(2), handle(2), L2CAP len(2) and CID(2)

#define L2CAP_BROADCAST_MIN_OFFSET   11

Minimum offset for broadcast needs another two bytes for the PSM

#define L2CAP_CHNL_DATA_RATE_HIGH   3

Values for Tx/Rx data rate parameter to wiced_bt_l2cap_set_chnl_data_rate

#define L2CAP_CHNL_PRIORITY_HIGH   0

Values for priority parameter to wiced_bt_l2cap_set_tx_priority

#define L2CAP_DATAWRITE_FAILED   FALSE

Result codes for wiced_bt_l2cap_data_write()

#define L2CAP_DEFAULT_BLE_CB_POOL_ID   0xFF

Use the default HCI ACL buffer pool

#define L2CAP_DIRECTION_DATA_SINK   2

Set ACL priority direction as sink

#define L2CAP_DIRECTION_DATA_SOURCE   1

Set ACL priority direction as source

#define L2CAP_DIRECTION_IGNORE   0

Values for direction parameter to wiced_bt_l2cap_set_acl_priority Set ACL priority direction as ignore

#define L2CAP_FCR_CHAN_OPT_BASIC   (1 << L2CAP_FCR_BASIC_MODE)

Values for 'allowed_modes' field passed in structure wiced_bt_l2cap_ertm_information_t

#define L2CAP_FLUSH_CHANNELS_ALL   0xffff

Used in wiced_bt_l2cap_flush_channel num_to_flush definitions

#define L2CAP_FLUSHABLE_MASK   0x0003

Data Packet Flags (bits 2-15 are reserved) layer specific 14-15 bits are used for FCR SAR. Used in call to wiced_bt_l2cap_data_write()

#define L2CAP_MINIMUM_OFFSET   13

plus control(2), SDU length(2)

#define L2CAP_PING_RESULT_NO_LINK   1

Link could not be setup

#define L2CAP_PING_RESULT_NO_RESPONSE   2

Remote L2CAP did not reply

#define L2CAP_PING_RESULT_OK   0

Ping result codes Ping reply received OK

#define L2CAP_PRIORITY_NORMAL   0

Values for priority parameter to wiced_bt_l2cap_set_acl_priority

#define L2CAP_ROLE_ALLOW_SWITCH   0x80

set this bit to allow switch at create conn

#define L2CAP_ROLE_DISALLOW_SWITCH   0x40

set this bit to disallow switch at create conn

#define L2CAP_ROLE_SLAVE   HCI_ROLE_SLAVE

Definition used for wiced_bt_l2cap_set_desire_role

#define MINIMIUM_DYNAMIC_LE_PSM   0x0080

Validity check for LE_PSM. Fixed LE_PSMs are in the range 0x0001 - 0x007F. Dynamic LE_PSM are in the range 0x0080 - 0x00FF. The values 0x0000 and 0x0100 - 0xFFFF are reserved.
