Expand description

An L2CAP CoC event, delivered on the host task to the single l2cap_subscribe hook. The hook returns an ATT-style status (0 = ok); it is only consulted for Accept, where non-zero rejects the peer.

Variants§

§

Connected

A channel opened by l2cap_connect finished connecting; check status (0 = success) before using chan.

Fields

§conn_handle: ConnHandle
§status: i32
§chan: L2capChan
§

Disconnected

A channel disconnected. chan must not be used after this event.

Fields

§conn_handle: ConnHandle
§chan: L2capChan
§

Accept

An incoming connection to one of our l2cap_create_server PSMs. The handler must provide the first receive buffer by calling l2cap_recv_ready on chan, and may reject the peer by returning non-zero from the hook.

Fields

§conn_handle: ConnHandle
§peer_sdu_size: u16
§chan: L2capChan
§

Received

An SDU was received. data is valid only for the duration of the call. After handling it, replenish the peer’s credits with l2cap_recv_ready.

Fields

§conn_handle: ConnHandle
§chan: L2capChan
§data: Mbuf<'a>
§

TxUnstalled

A previously Stalled send can continue (credits replenished). status is non-zero only on an allocation error mid-SDU.

Fields

§conn_handle: ConnHandle
§status: i32
§chan: L2capChan
§

Reconfigured

A channel MTU reconfiguration completed. by_peer is false for a local reconfigure completing (RECONFIG_COMPLETED) and true when the peer reconfigured us (PEER_RECONFIGURED).

Fields

§conn_handle: ConnHandle
§status: i32
§chan: L2capChan
§by_peer: bool
