Struct esp32_nimble::BLECharacteristic

pub struct BLECharacteristic { /* private fields */ }

Implementations

impl BLECharacteristic

pub fn uuid(&self) -> BleUuid

pub fn set_value(&mut self, value: &[u8]) -> &mut Self

pub fn set_from<T: Sized>(&mut self, value: &T) -> &mut Self

pub fn value_mut(&mut self) -> &mut AttValue

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

pub fn on_write( &mut self, callback: impl FnMut(&mut OnWriteArgs<'_>) + Send + Sync + 'static, ) -> &mut Self

This characteristic is locked while the callback is executing. If you call .lock() on this characteristic from inside the callback, it will never execute.

pub fn on_notify_tx( &mut self, callback: impl FnMut(NotifyTx<'_>) + Send + Sync + 'static, ) -> &mut Self

pub fn create_descriptor( &mut self, uuid: BleUuid, properties: DescriptorProperties, ) -> Arc<Mutex<BLEDescriptor>>

pub fn create_2904_descriptor(&mut self) -> BLE2904

pub fn notify(&self)

pub fn cpfd(&mut self, cpfd: Cpfd)

Set the Characteristic Presentation Format.

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

Do not call lock on this characteristic inside the callback, use the first input instead. In the future, this characteristic could be locked while the callback executes.

• callback - Function to call when a subscription event is recieved, including subscribe and unsubscribe events see crate::NimbleSub for event type

pub fn subscribed_count(&self) -> usize
