L2capChan

esp_idf_svc::ble::l2cap

Struct L2capChan

pub struct L2capChan(/* private fields */);

Expand description

An opaque handle to an open L2CAP channel (wraps *mut ble_l2cap_chan).

§Validity

A handle is valid only while its channel is open — from L2capEvent::Connected / L2capEvent::Accept until the matching L2capEvent::Disconnected. Using it afterwards is undefined behavior (it dereferences freed NimBLE state). It is Send/Sync so it can be stashed and used from another task (NimBLE serializes internally with its own lock) — which is exactly why honoring the “not after Disconnected” rule is the caller’s responsibility.
