At the moment, there is only retry logic for the ACK/NAK byte. Corrupt data packets (e.g. wrong checksum, unexpected length, etc) are treated as a fatal error. By reading the entire packet inside the retry loop, all non-fatal errors are automatically taken care off. This change is necessary for the Oceanic VTX. For some unknown reason, the device always responds with an invalid data packet when sending the version command for the first time: W: 84 00 R: 5A 4F ?? 45 41 4E 56 54 58 20 31 42 20 32 30 34 38 E9 There is always one byte missing (marked with question marks), resulting in a timeout. However, when re-sending the command again, we receive a valid data packet: W: 84 00 R: 5A 4F 43 45 41 4E 56 54 58 20 31 42 20 32 30 34 38 E9 This might be a firmware bug, because we're observing the exact same behaviour with the official Oceanlog application.
Overview ======== Libdivecomputer is a cross-platform and open source library for communication with dive computers from various manufacturers. The official web site is: http://www.libdivecomputer.org/ The sourceforge project page is: http://sourceforge.net/projects/libdivecomputer/ Installation ============ On UNIX-like systems (including Linux, Mac OS X, MinGW), use the autotools based build system. Run the following commands from the top directory (containing this file) to configure, build and install the library and utilities: $ ./configure $ make $ make install If you downloaded the libdivecomputer source code directly from the git source code repository, then you need to create the configure script as the first step: $ autoreconf --install To uninstall libdivecomputer again, run: $ make uninstall Support ======= Please send bug reports, feedback or questions to the mailing list: http://libdivecomputer.org/cgi-bin/mailman/listinfo/devel or contact me directly: jef@libdivecomputer.org License ======= Libdivecomputer is free software, released under the terms of the GNU Lesser General Public License (LGPL).
