Implementations

impl BLEServer

pub fn on_connect( &mut self, callback: impl FnMut(&mut Self, &BLEConnDesc) + Send + Sync + 'static ) -> &mut Self

pub fn on_disconnect( &mut self, callback: impl FnMut(&BLEConnDesc, Result<(), BLEError>) + Send + Sync + 'static ) -> &mut Self

Handle a client disconnection.

• callback first parameter: A reference to a esp_idf_sys::ble_gap_conn_desc instance with information about the peer connection parameters.
• callback second parameter: The reason code for the disconnection.

pub fn on_passkey_request( &mut self, callback: impl Fn() -> u32 + Send + Sync + 'static ) -> &mut Self

Set a callback fn for generating a passkey if required by the connection

• The passkey will always be exactly 6 digits. Setting the passkey to 1234 will require the user to provide ‘001234’
• a static passkey can also be set by crate::BLESecurity::set_passkey

pub fn on_confirm_pin( &mut self, callback: impl Fn(u32) -> bool + Send + Sync + 'static ) -> &mut Self

pub fn on_authentication_complete( &mut self, callback: impl Fn(&BLEConnDesc, Result<(), BLEError>) + Send + Sync + 'static ) -> &mut Self

The callback function is called when the pairing procedure is complete.

• callback first parameter: A reference to a BLEConnDesc instance.
• callback second parameter: Indicates the result of the encryption state change attempt; o 0: the encrypted state was successfully updated; o BLE host error code: the encryption state change attempt failed for the specified reason.

pub fn start(&mut self) -> Result<(), BLEError>

pub fn disconnect(&mut self, conn_id: u16) -> Result<(), BLEError>

Disconnect the specified client.

pub fn disconnect_with_reason( &mut self, conn_id: u16, reason: u8 ) -> Result<(), BLEError>

Disconnect the specified client with optional reason.

pub fn ble_gatts_show_local(&self)

Prints dump of local GATT database. This is useful to log local state of database in human readable form.

pub fn connected_count(&self) -> usize

pub fn connections(&self) -> impl Iterator<Item = BLEConnDesc> + '_

pub fn create_service(&mut self, uuid: BleUuid) -> Arc<Mutex<BLEService>>

pub fn advertise_on_disconnect(&mut self, value: bool) -> &mut Self

Set the server to automatically start advertising when a client disconnects.

pub fn update_conn_params( &mut self, conn_handle: u16, min_interval: u16, max_interval: u16, latency: u16, timeout: u16 ) -> Result<(), BLEError>

Request an Update the connection parameters: Can only be used after a connection has been established.

• conn_handle: The connection handle of the peer to send the request to.
• min_interval: The minimum connection interval in 1.25ms units.
• max_interval: The maximum connection interval in 1.25ms units.
• latency: The number of packets allowed to skip (extends max interval).
• timeout: The timeout time in 10ms units before disconnecting.
