Function init 

pub fn init<'d>() -> Result<Controller<'d>, InitializationError>

Initialize for using Wi-Fi and or BLE.

Wi-Fi and BLE require a preemptive scheduler to be present. Without one, the underlying firmware can’t operate. The scheduler must implement the interfaces in the esp-radio-rtos-driver crate. If you are using an embedded RTOS like Ariel OS, it needs to provide an appropriate implementation.

If you are not using an embedded RTOS, use the esp-rtos crate which provides the necessary functionality.

Make sure to not call this function while interrupts are disabled.

Errors

• The function may return an error if the scheduler is not initialized.
• The function may return an error if interrupts are disabled.
• The function may return an error if initializing the underlying driver fails.

Example

For examples of the necessary setup, see your RTOS’s documentation. If you are using the esp-rtos crate, you will need to initialize the scheduler before calling this function:

use esp_hal::timer::timg::TimerGroup;

let timg0 = TimerGroup::new(peripherals.TIMG0);
 let software_interrupt = SoftwareInterruptControl::new(peripherals.SW_INTERRUPT);
 esp_rtos::start(timg0.timer0, software_interrupt);
// You can now start esp-radio:
let esp_radio_controller = esp_radio::init().unwrap();
