Struct nrf_softdevice::Softdevice

pub struct Softdevice { /* private fields */ }

Singleton instance of the enabled softdevice.

The Softdevice instance can be obtaind by enabling it with Softdevice::enable. Once enabled, it can be used to establish Bluetooth connections with [ble::central] and [ble::peripheral].

Disabling the softdevice is not supported due to the complexity of a safe implementation. Consider resetting the CPU instead.

Implementations

impl Softdevice

pub fn enable(config: &Config) -> &'static mut Softdevice

Enable the softdevice.

Panics

• Panics if the requested configuration requires more memory than reserved for the softdevice. In that case, you can give more memory to the softdevice by editing the RAM start address in memory.x. The required start address is logged prior to panic.
• Panics if the requested configuration has too high memory requirements for the softdevice. The softdevice supports a maximum dynamic memory size of 64kb.
• Panics if called multiple times. Must be called at most once.

pub unsafe fn steal() -> &'static Softdevice

Return an instance to the softdevice without checking whether it is enabled or not. This is only safe if the softdevice is enabled (a call to [enable] has returned without error) and no &mut references to the softdevice are active

pub async fn run(&self) -> !

Runs the softdevice event handling loop.

It must be called in its own async task after enabling the softdevice and before doing any operation. Failure to doing so will cause async operations to never finish.

pub async fn run_with_callback<F: FnMut(SocEvent)>(&self, f: F) -> !

Runs the softdevice event handling loop with a callback for SocEvents.

It must be called under the same conditions as Softdevice::run(). This version allows the application to provide a callback to receive SoC events from the softdevice (other than flash events which are handled by Flash).

pub async fn run_soc(&self) -> !

Runs the softdevice soc event handler only.

It must be called under the same conditions as Softdevice::run().

pub async fn run_ble(&self) -> !

Runs the softdevice ble event handler only.

It must be called under the same conditions as Softdevice::run().
