CHANGELOG.md.

Contents

v2.2.1

  • Add decimal msg_id to PDF docs
  • Fix bug in pyserial driver that could hang and prevent exit
  • Fix ephemeris time to be seconds as it exists in all implementation

v2.2.0

  • Add Network Status Msg
  • Redefine Nanoseconds field of UTC time message as U32 rather than S32
  • Redefine Seconds field of UTC message as the floor of the current seconds in minute
  • Rename ns field that was a residual to ns_residual
  • Add RTCS/CTS option to python serial driver
  • Increase Network Driver timeouts for connection and reads
  • Add context manager to python client forwarder

v2.1.8

  • Add MSG_ALMANAC_GPS (0x70)
  • Add MSG_ALMANC_GLO (0x71)

v2.1.7

  • python client improvments (threadsafe write)
  • Python network driver improvements (verbosity in connection issues)

v2.1.6

  • Add MSG_NDB_EVENT

v2.1.5

  • Add CDC driver for usb CDC AMC devices
  • New flags to the reset message for commanded resets
  • Add DGNSS flag to solution messages
  • Add IMU raw data messages
  • Remove RAIM flag from solution messages

v2.1.0

  • Add command and response messages
  • Clarify height field is above ellipsoid

v2.0.0

  • Deprecated and redefined all navigation messages due to redefinition of the FLAGS field
    • Navigation messages are expected to go out with every solution epoch whether valid or not
  • New observation message with Measured Doppler addition, observation flags, and lock timer
  • Deprecation of Piksi V2.3.1 bootloader and flash messages
  • Addition of MSG_FWD to allow wrapping of forwardes SBP or other protocol messages
  • Addition of UTC Time message
  • Addition of DGPS Status Message. This message will go out with each receipt of base observations.
  • Addition of Age of corrections message. This will go out with every solution epoch to indicate correction age
  • Add information fields to reserved word in MSG_STARTUP definition

v1.1.1

  • Javascript: fixed bug with constructMsg and added more tests and examples for message construction.

v1.1.0

  • Added MSG_SETTINGS_REGISTER message
  • More improvements to JavaScript to add a constructMsg interface (sbp/construct.js).

v1.0.2

Minor release: changes JavaScript bindings to simplify constructing
SBP messages.

v1.0.1

Many changes since the last update to the release notes.

  • New Observation message format (which triggered a major version
    increment)
  • New UART State message format
  • Haskell Bindings
  • Java Bindings
  • Javascript Bindings
  • Improvements to python client libraries and iterative interface
    abstraction

v0.39

Bug fixes, minor additions, and stability enhancements since
v0.33.

Specifications

  • New external events trigger message.
  • The ephemeris message is now included in the list of messages to be
    sent over the radio. The ephemeris' field names have been changed to
    avoid clashing with existing SBP fields (e.g., 'crc' to 'c_rc').

Python Library

  • Easier to actually materialize a message in place using fields and
    create a new SBP packet to send over the wire. Previously, you
    could only create message objects by deserializing from an existing
    SBP message!
  • Robustness improvements for serializing message types to/from JSON.
  • Piksi serial link command line tool (serial_link.py) now lives in
    piksi_tools.

Datasheet Documentation

  • More stable datasheet generation when adding new messages ("the
    floats are too dang high!" and automatic versioning from git tags).

v0.33

First standalone release of libsbp, the native binary messaging
protocol used by Swift Navigation devices. This is a core messaging
dependency for interfacing and integration with the
Piksi GPS receiver.

Specifications

  • Centralized and detailed definitions of many, if not all, SBP
    messages output by the Piksi, including messages used only for
    internal development. Previously, some messages were either
    undocumented and created inline by their callers in the firmware or
    the Piksi console.
  • Definitions are grouped into files by functionality in a
    machine-readable format, YAML,
    and include some annotated examples and example test cases for
    writers of new language bindings.
  • A Python-based generator for our C and Python libraries, as well as
    the Piksi datasheet. This is still a major work-in-progress.

C Library

  • C header files for SBP message types and library support for parsing
    such messages. This library is now a dependency of the Piksi
    firmware project.
  • Updated Doxygen developer documentation. Available
    here.

Python Library

  • Binary parsing for all message types, as well as serial port
    handlers and helpers. This is used by the Piksi
    console. Note that
    because messages are now grouped by functionality, some messages
    that were once imported by import sbp_piksi are now located in
    different Python submodules. If such changes aren't clear, please
    don't hesitate to ask a question on the
    forum.
  • The serial port client binary for the Piksi is a part of Piksi's
    tools.
  • The latest stable version is available on
    PyPi.
  • Updated Sphinx developer documentation. Available
    here.

Datasheet Documentation

  • A standalone .pdf
    datasheet
    describing SBP and message layouts.
