Detailed Description

Device Firmware Update (DFU) transport layer for Bluetooth low energy.

The Device Firmware Update (DFU) Service is a GATT-based service that can be used for performing firmware updates over BLE. Note that this implementation uses vendor-specific UUIDs for the service and characteristics, and is intended to demonstrate firmware updates over BLE. See DFU Transport: BLE for more information on the service and the profile.

Function Documentation

uint32_t ble_dfu_transport_close

(

nrf_dfu_transport_t const *

p_exception

)

Function for closing the BLE transport.

This function disconnects and disables the SoftDevice.

Parameters

[in]

p_exception

Optional exception. If the exception refers to this transport, this function will do nothing. Can be NULL to signify no exception.

Return values

NRF_SUCCESS

If successful.

Returns

Error code from sub-call on error.

uint32_t ble_dfu_transport_disconnect

(

void

)

Function for disconnecting from the BLE peer and starting advertising.

Return values

NRF_SUCCESS

If successful.

Returns

Error code from sub-call on error.

uint32_t ble_dfu_transport_init

(

nrf_dfu_observer_t

observer

)

Function for initializing the BLE transport.

Parameters

[in]

observer

Callback function for receiving notifications from the BLE transport.

Return values

NRF_SUCCESS

If successful.

Returns

Error code from sub-call on error.
