Trying to fill some gaps in documentation
by C470IP 30 Oct '12

30 Oct '12

Hello! Recently I've managed to install all Osmocom-DECT components (except Asterisk, which will be installed later). Everything seem to be working fine, at least I could try examples from the website without any error. Many thanks to the authors for this extraordinary job. Now I want to go further and to configure some useful system using these tools, but I feel some gaps in documentation/description which need to be clarified. I would be very thankful to anybody who would bother to answer the following questions: 1) When a DECT cluster is configured in FP mode (like first example here: http://dect.osmocom.org/trac/dect/wiki/Configuration ), how can we use it to attach handsets? Or for what this mode is for? Also I've found that in this mode beacon frames are sent very seldom and with minimal power, is this normal? 2) Where one can find the list of keywords for dectmon command line? Or if not keywords, what is dectmon awaiting after its > character? 3) In which program can we open raw dump files created by dectmon? Is it possible to dump pcap from dectmon? 4) How can we extract audio from the monitored stream? For example I created a cluster in PP mode locked to my unencrypted phone, then created a cell and bound the transceiver, then ran dectmon with '-a yes' keys. No success at all. 5) Is it possible to extract audio from raw dumps of dectmon with some ready-to use software? 6) BTW does dectmon support seamless channel hopping to make smooth audio streams without noise interrupts like those happening in dect_cli software? Would be grateful for any response. With best regards, C470IP. E-mail: c470ip(a)yandex.ru

Hello! While compiling libnl I get the following errors: route/cls/ematch_grammar.c:773:5: error: unknown type name 'YYSTYPE' route/cls/ematch_grammar.c:816:1: error: unknown type name 'YYSTYPE' route/cls/ematch_grammar.c:818:23: error: unknown type name 'YYSTYPE' route/cls/ematch_grammar.c:931:17: error: unknown type name 'YYSTYPE' route/cls/ematch_grammar.c:954:1: error: unknown type name 'YYSTYPE' route/cls/ematch_grammar.c:2433:1: error: unknown type name 'YYSTYPE' route/cls/ematch_grammar.c:2439:23: error: unknown type name 'YYSTYPE' route/cls/ematch_grammar.c:1766:26: warning: 'yy_get_previous_state' defined but not used [-Wunused-function] route/cls/ematch_grammar.c:1799:26: warning: 'yy_try_NUL_trans' defined but not used [-Wunused-function] route/cls/ematch_grammar.c:1631:12: warning: 'yy_get_next_buffer' defined but not used [-Wunused-function] make[2]: *** [route/cls/ematch_grammar.lo] Error 1 make[2]: Exiting `/libnl/lib' make[1]: *** [all] Error 2 make[1]: Exiting `/libnl/lib' make: *** [all-recursive] Error 1 I've tried bison 2.2, 2.3 and 2.6.2 with no success. Byacc and flex are also installed. Is it possible to fix these errors somehow? Unfortunately my knowledge of source syntax is not sufficient. With best regards, C470IP.
