The new APOS4 firmware changed the data format and communication protocol. The size of the samples changed from 54 to 64 bytes, and in order to speedup the download, a single data packet contains 3 samples at once. If the number of samples is not an exact multiple of three, the last packet appears to contain garbage data. For parsing, the firmware version is available in the dive header. Unfortunately it can't be used for dives that are downloaded from a device with the new firmware, but which have been recorded with an older firmware. Such dives store the old firmware version in the dive header, but they also use the new sample format. As a workaround, we inspect the size of the dive.
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.
