Detailed Description

Bootloader with Device Firmware Update (DFU) functionality.

The DFU bootloader module, in combination with the Bootloader module, can be used to implement a bootloader that supports Device Firmware Updates.

Function Documentation

bool nrf_dfu_button_enter_check ( void )

Function to check if button was pressed.

Note: This function must be implemented by the application to enable entering bootloader mode based on button press.

Return values

true	if the DFU mode should be entered, otherwise false.

bool nrf_dfu_check_failsafe_reset ( void )

Function for checking if DFU should be reset (failsafe).

This function will check if DFU should be reset (failsafe).

If this returns true, DFU mode will be entered and DFU will be reset.

Return values

true	If DFU must be reset (failsafe).
false	If there is no need to reset DFU.

bool nrf_dfu_enter_check ( void )

Function for checking if DFU mode should be entered.

This function checks whether DFU mode is required.

Return values

true	If DFU mode must be entered.
false	If there is no need to enter DFU mode.

uint32_t nrf_dfu_init ( void )

Function for initializing a DFU operation.

This function initializes a DFU operation and any transports that are registered in the system.

Return values

NRF_SUCCESS If the DFU operation was successfully initialized.
