Detailed Description

Connectionless data channel callback structure.

This structure is used for tracking the connectionless data channel frames. It is registered with the help of the bt_l2cap_br_connless_register() API. It's permissible to register multiple instances of this bt_l2cap_br_connless_cb type, in case different modules of an application are interested in tracking the connectionless data channel frames.

Field Documentation

psm

uint16_t bt_l2cap_br_connless_cb::psm

Register PSM.

For BR, possible values:

The PSM field is at least two octets in length. All PSM values shall have the least significant bit of the most significant octet equal to 0 and the least significant bit of all other octets equal to 1.

0 Any connectionless data channel frame will be notified.

0x0001-0x0eff Standard, Bluetooth SIG-assigned fixed values.

‍0x1000 Dynamically allocated. May be pre-set by the application before server registration (not recommended however), or auto-allocated by the stack if the app gave 0 as the value.

recv

void(* bt_l2cap_br_connless_cb::recv) (struct bt_conn *conn, uint16_t psm, struct net_buf *buf)

A connectionless channel data has been received.

This callback notifies the application of a connectionless channel data has been received.

Parameters

conn	The ACL connection object.
psm	Protocol/Service Multiplexer.
buf	Received connectionless channel data.

sec_level

bt_security_t bt_l2cap_br_connless_cb::sec_level

Required minimum security level.
