Detailed Description

Device Firmware Update (DFU) transport layer using UART.

The transport layer can be used for performing firmware updates over UART. The implementation uses SLIP to encode packets.

Enumeration Type Documentation

Serial DFU opcodes.

Enumerator
SERIAL_DFU_OP_CODE_CREATE_OBJECT	Value of the opcode field for a 'Create object' request.
SERIAL_DFU_OP_CODE_SET_RECEIPT_NOTIF	Value of the opcode field for a 'Set Packet Receipt Notification' request.
SERIAL_DFU_OP_CODE_CALCULATE_CRC	Value of the opcode field for a 'Calculating checksum' request.
SERIAL_DFU_OP_CODE_EXECUTE_OBJECT	Value of the opcode field for an 'Initialize DFU parameters' request.
SERIAL_DFU_OP_CODE_SELECT_OBJECT	Value of the opcode field for a 'Select object' request.
SERIAL_DFU_OP_CODE_GET_SERIAL_MTU	Value of the opcode field for a 'Get Serial MTU' request.
SERIAL_DFU_OP_CODE_WRITE_OBJECT	Value of the opcode indicating a write to the current object.
SERIAL_DFU_OP_CODE_RESPONSE	Value of the opcode field for a response.

uint32_t serial_dfu_transport_close ( void )

Function for closing down the transport layer.

Return values

NRF_SUCCESS If the transport layer was correctly closed down.

uint32_t serial_dfu_transport_init ( void )

Function for initializing the transport layer.

Return values

NRF_SUCCESS If the transport layer was successfully initialized. Otherwise, an error code is returned.
