Struct ExternalController

pub struct ExternalController<T, const SLOTS: usize> { /* private fields */ }

An external Bluetooth controller with communication via Transport type T.

The controller state holds a number of command slots that can be used to issue commands and await responses from an underlying controller.

The contract is that before sending a command, a slot is reserved, which returns a signal handle that can be used to await a response.
