Detailed Description

LE L2CAP Channel structure.

Field Documentation

◆ chan

struct bt_l2cap_chan bt_l2cap_le_chan::chan

Common L2CAP channel reference object.

◆ pending_rx_mtu

uint16_t bt_l2cap_le_chan::pending_rx_mtu

Pending RX MTU on ECFC reconfigure, used internally by stack.

◆ rx

struct bt_l2cap_le_endpoint bt_l2cap_le_chan::rx

Channel Receiving Endpoint.

If the application has set an alloc_buf channel callback for the channel to support receiving segmented L2CAP SDUs the application should initialize the MTU of the Receiving Endpoint. Otherwise the MTU of the receiving endpoint will be initialized to BT_L2CAP_SDU_RX_MTU by the stack.

This is the source of the MTU, MPS and credit values when sending L2CAP_LE_CREDIT_BASED_CONNECTION_REQ/RSP and L2CAP_CONFIGURATION_REQ.

◆ tx

struct bt_l2cap_le_endpoint bt_l2cap_le_chan::tx

Channel Transmission Endpoint.

This is an image of the remote's rx.

The MTU and MPS is controlled by the remote by L2CAP_LE_CREDIT_BASED_CONNECTION_REQ/RSP or L2CAP_CONFIGURATION_REQ.

◆ tx_queue

struct k_fifo bt_l2cap_le_chan::tx_queue

Channel Transmission queue (for SDUs)
