typedef int fd_t

## Function Documentation

## bfb_assemble_data()

int bfb_assemble_data | ( | bfb_data_t ** | data,
|  | int * | size,
|  | int * | len,
|  | bfb_frame_t * | frame
| ) |  |

Append BFB frame to a data buffer.

## bfb_check_data()

int bfb_check_data | ( | bfb_data_t * | data,
|  | int | len
| ) |  |

Check if data buffer is complete and valid.

## bfb_checksum()

uint8_t bfb_checksum | ( | uint8_t * | data,
|  | int | len
| ) |  |

Returns the whole buffer folded with xor.

## bfb_read_packets()

bfb_frame_t* bfb_read_packets | ( | uint8_t * | buffer,
|  | int * | length
| ) |  |

Retrieve actual packets.

## bfb_send_data()

int bfb_send_data | ( | fd_t | fd,
|  | uint8_t | type,
|  | uint8_t * | data,
|  | uint16_t | length,
|  | uint8_t | seq
| ) |  |

## bfb_stuff_data()

int bfb_stuff_data | ( | uint8_t * | buffer,
|  | uint8_t | type,
|  | uint8_t * | data,
|  | uint16_t | len,
|  | uint8_t | seq
| ) |  |

Stuff data frame into serial cable encapsulation.

buffer needs to be of at leaset len+7 size Type 0x01: "prepare" command. Type 0x02: first transmission in a row. Type 0x03: continued transmission. seq needs to be incremented afterwards.

## bfb_write_packets()

int bfb_write_packets | ( | fd_t | fd,

Send actual packets.

Patch from Jorge Ventura to handle EAGAIN from write.
