Macro Definition Documentation

L2C_INVALID_PSM

#define L2C_INVALID_PSM

(

psm

)

Value:

(((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.

L2CAP_BLE_COC_SDU_OFFSET

#define L2CAP_BLE_COC_SDU_OFFSET   4

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

L2CAP_BLE_CONN_MIN_OFFSET

#define L2CAP_BLE_CONN_MIN_OFFSET   9

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

L2CAP_BROADCAST_MIN_OFFSET

#define L2CAP_BROADCAST_MIN_OFFSET   11

Minimum offset for broadcast needs another two bytes for the PSM

L2CAP_CHNL_DATA_RATE_HIGH

#define L2CAP_CHNL_DATA_RATE_HIGH   3

Values for Tx/Rx data rate parameter to wiced_bt_l2cap_set_chnl_data_rate

L2CAP_CHNL_PRIORITY_HIGH

#define L2CAP_CHNL_PRIORITY_HIGH   0

Values for priority parameter to wiced_bt_l2cap_set_tx_priority

L2CAP_DATAWRITE_FAILED

#define L2CAP_DATAWRITE_FAILED   FALSE

Result codes for wiced_bt_l2cap_data_write()

L2CAP_DEFAULT_BLE_CB_POOL_ID

#define L2CAP_DEFAULT_BLE_CB_POOL_ID   0xFF

Use the default HCI ACL buffer pool

L2CAP_DIRECTION_DATA_SINK

#define L2CAP_DIRECTION_DATA_SINK   2

Set ACL priority direction as sink

L2CAP_DIRECTION_DATA_SOURCE

#define L2CAP_DIRECTION_DATA_SOURCE   1

Set ACL priority direction as source

L2CAP_DIRECTION_IGNORE

#define L2CAP_DIRECTION_IGNORE   0

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

L2CAP_FCR_CHAN_OPT_BASIC

#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

L2CAP_FLUSH_CHANNELS_ALL

#define L2CAP_FLUSH_CHANNELS_ALL   0xffff

Used in wiced_bt_l2cap_flush_channel num_to_flush definitions

L2CAP_FLUSHABLE_MASK

#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()

L2CAP_MINIMUM_OFFSET

#define L2CAP_MINIMUM_OFFSET   13

plus control(2), SDU length(2)

L2CAP_PING_RESULT_NO_LINK

#define L2CAP_PING_RESULT_NO_LINK   1

Link could not be setup

L2CAP_PING_RESULT_NO_RESPONSE

#define L2CAP_PING_RESULT_NO_RESPONSE   2

Remote L2CAP did not reply

L2CAP_PING_RESULT_OK

#define L2CAP_PING_RESULT_OK   0

Ping result codes Ping reply received OK

L2CAP_PRIORITY_NORMAL

#define L2CAP_PRIORITY_NORMAL   0

Values for priority parameter to wiced_bt_l2cap_set_acl_priority

L2CAP_ROLE_ALLOW_SWITCH

#define L2CAP_ROLE_ALLOW_SWITCH   0x80

set this bit to allow switch at create conn

L2CAP_ROLE_DISALLOW_SWITCH

#define L2CAP_ROLE_DISALLOW_SWITCH   0x40

set this bit to disallow switch at create conn

L2CAP_ROLE_SLAVE

#define L2CAP_ROLE_SLAVE   HCI_ROLE_SLAVE

Definition used for wiced_bt_l2cap_set_desire_role

MINIMIUM_DYNAMIC_LE_PSM

#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.
