Implementations

impl<P: Packet> L2cap<P>

pub fn init(_sd: &Softdevice) -> Self

Initialize the driver. Panics if called multiple times.

pub async fn setup( &self, conn: &Connection, config: &Config, psm: u16 ) -> Result<Channel<P>, SetupError>

Send a setup request to the peer to establish a channel with the PSM given in psm. The peer will accept the request and establish a channel if it deems the PSM acceptable.

pub async fn listen( &self, conn: &Connection, config: &Config, psm: u16 ) -> Result<Channel<P>, SetupError>

Listen for setup requests of the peer. When a setup request with the PSM given in psm comes in the channel is established.

pub async fn listen_with( &self, conn: &Connection, config: &Config, accept_psm: impl FnMut(u16) -> bool ) -> Result<(u16, Channel<P>), SetupError>

Listen for setup requests of the peer. When a setup request comes in the PSM sent by the peer is passed to the accept_psm function. If it returns true the channel is established.
