MAVCONN library

It is mavlink connection and communication library used in MAVROS. Since 2014-11-02 it adopted to use outside from ROS environment by splitting to individual package and removing dependencies to rosconsole.

Connection URL

Connection defined by URL. Just pass one of that URL to MAVConnInterface::open_url() and get connection object.

Supported schemas:

• Serial: /path/to/serial/device[:baudrate]
• Serial: serial:///path/to/serial/device[:baudrate][?ids=sysid,compid]
• Serial with hardware flow control: serial-hwfc:///path/to/serial/device[:baudrate][?ids=sysid,compid]
• UDP: udp://[bind_host][:port]@[remote_host][:port][/?ids=sysid,compid]
• UDP broadcast until GCS discovery: udp-b://[bind_host][:port]@[:port][/?ids=sysid,compid]
• UDP broadcast (permanent): udp-pb://[bind_host][:port]@[:port][/?ids=sysid,compid]
• TCP client: tcp://[server_host][:port][/?ids=sysid,compid]
• TCP server: tcp-l://[bind_port][:port][/?ids=sysid,compid]

Note: ids from URL overrides ids given by system_id & component_id parameters.

Dependencies

Same as for mavros:

• Linux host
• Asio library ( https://think-async.com/Asio/ )
• console-bridge library
• compiller with C++14 support

• 1.13.0
• update changelog
• Merge pull request #1682 from SylvainPastor/fix/libmavconn/tcp/resource_deadlock fix std::system_error when tcp interface loses connection
• fix code style divergences
• fix std::system_error when tcp interface loses connection When the tcp connection is lost (remote TCP server stopped), an 'End of file' error is caught by the io_thread in the do_recv() that calls the close() function. In the close() function, we stop the io_service and wait for the end of the io_thread which causes an std::system_error exception (cause: Resource deadlock avoided). Error: mavconn: tcp0: receive: End of file at line 250 in libmavconn/src/tcp.cpp terminate called after throwing an instance of 'std::system_error' what(): Resource deadlock avoided Aborted (core dumped) fix:
  • close() function: stop io_service if current thread id != io_thread id
  • ~MAVConnTCPClient(): stop io_service and io_thread if thread is running
• Merge pull request #1679 from SylvainPastor/libmavconn/fix-tcp-deadlock-when-close libmavconn: fix deadlock when call close()
• fix deadlock when call close() When calling the close() function (by a different thread), a lock (mutex) is taken at the start of this function which closes the socket and waits the end of io_service thread. Closing the socket causes the 'Operation aborted' error in do_recv() function called by io_service thread which in turn calls the close() function: sthis->close(). This causes a 'deadlock'. fix: Reduce the scope of the lock in the close() function so that it is released before waiting for the thread to end.

0.33.0 (2019-10-10)

• libmavconn: simplify parse_buffer, and fix dropped_packets and parse_error counters Currently the dropped_packets & parse_error counters are always published as 0 in mavros_diag.cpp. This seems to be caused by using the wrong status struct. Seems like mavros was editing m_status after mavlink_frame_char_buffer. This struct seems to be the parsing state, and looks like it shouldn't be modified by the caller (for example status->parse_error is zeroed out in the end of mavlink_frame_char_buffer). Also, the crc & signature checks done in mavros seems redundant. r_mavlink_status seems to be the struct that holds the mavlink connection information, therefore I changed get_status to return it instead. This fixes #1285.

• libmavconn: make serial.cpp more portable
• libmavconn : enable low-latency mode on Linux Some common USB-UART convertors like the FTDI accumulates individual bytes from the serial link in order to send them in a single USB packet (Nagling). This commit sets the ASYNC_LOW_LATENCY flag, which the FTDI kernel driver interprets as a request to drop the Nagling timer to 1ms (i.e send all accumulated bytes after 1ms.) This reduces average link RTT to under 5ms at 921600 baud, and enables the use of mavros in systems where low latency is required to get good performance for e.g estimation and controls.

0.23.1 (2018-02-27)

• compile also with boost >= 1.66.0 In boost 1.66.0, which includes boost-asio 1.12.0, the asio interfaces have been changed to follow the "C++ Extensions for Networking" Technical Specification [1]. As a consequence, resolvers now produce ranges rather than iterators. In boost < 1.66.0, resolver.resolve returns an iterator that must be passed to [std::for_each]{.title-ref}. As this iterator in boost < 1.66.0 does not provide begin() and end() member functions, it cannot be simply turned into a proper range. For boost >= 1.66.0, resolver.resolve returns a range, which can be just iterated through with [for (auto v : _)]{.title-ref} syntax. As it is not possible to have one way to iterate through the result independent of the boost version, a preprocessing directive selects the proper synactic iteration construction depending on the provided boost-asio library version [2]. This way, this commit is backwards compatible with boost < 1.66.0 and compiles properly with boost >= 1.66.0. The issue was identified in a build with the cross-compilation tool chain provided in the meta-ros OpenEmbedded layer [3].

Now all debug will be enabled by one tag: [ros.rosconsole_bridge.mavconn]{.title-ref} And because its only used for debugging that was ok.
