Regenerate Friis indexes at each call of the algorithm when
autocalibration is used (without this fix, FBCM given always the same
result autocalibration activated, because of the Friis indexes equal to
zero).
Use AccessPoint::friis_constant_term() wherever possible.
Fix MultilaterationAlgorithm::make_constant_term() and
ReferencePoint::friis_indexes_for_ap(), where the AP's trx
power was used instead of the mobile's power.
Instead of #define DEBUG, we now prefer to use either verbose levels
or, when needed, NDEBUG. Each Makefile was modified to be able to pass
-D NDEBUG to the compiler (but the corresponding lines are commented),
except in the modules where assert is never used, in which case the
Makefile passes -D DEBUG.
Long story short: to totally disable debugging code, comment-out the
"-D DEBUG" lines and uncomment the "-D NDEBUG" lines, in every Makefile.
owl_mac_bytes_to_string() now uses a static buffer, so the caller do not
need to free the returned buffer manually. Because of this static
buffer, it is not thread-safe anymore, therefore we introduce
owl_mac_bytes_to_string_r() that is a thread-safe version.
Use owl_timestamp_is_null() instead of owl_timestamp_to_ms() to test if
a timestamp is empty or not.
Note that we cannot remove owl_timestamp_to_ms(), since it it used by
owl_time_elapsed_ms().
In capture(), the pcap_loop() call was blocking, so the program did not
quit if no packet came on rtap_iface. This is now fixed by a call to
pcap_breakloop() in the signal handlers.
Add some comments, add/remove some endianess conversions. That should be
OK now.
Noticeable changes in owlps.h:
- Type DIRECTION is now an alias for uint8_t instead of an enum.
- Type autocalibration_order now contains an uint8_t instead of an enum.
The use of integer types from inttypes.h & stdint.h should help with
portability issues. It will also force the data transmission between
different architectures to work as intended (if we handle endianess
conversions correctly!).
Abandon the old struct timeval and gettimeofday(). We now use the new
struct timespec and clock_gettime().
struct timespec has a nanosecond resolution, but we lower the resolution
to keep only milliseconds. The code is inspired from the Timestamp class
of the owlps-positioning.
== code/owlps-positioning ==
- Add new class Request (split of Measurement).
- Update Measurement and CalibrationMeasurement (suppress the 'mobile'
attribute).
- Update InputCSV (and InputMedium) to use Request instead of
Measurement. Complete the file reading (mobile & ap pointers remain to
be implemented).
- PosUtil: Add timespec_to_ms(), timespec_to_ns(), ms_to_timespec(), and
ns_to_timespec().
- Makefile: Update to use stlport, fix all deps and add new classes.
- Minor fixes.
- TODO: Add UML-related things, updates Measurement & Request.
== code ==
- libowlps: Add ms_to_timeval() (commented), may be useful later.
- Add TODO.
