joxe adb00ed932 factored out function for getting link local address in ds6 and made use of it in rpl for checking state of lladdress as DIOs should not be sent when tentative 2010-05-09 17:52:37 +00:00
oliverschmidt e5665fb968 The recent change turning uip_buf from an array to a pointer seems a quite heavyweight way to have the uip_buf alligned to a 32-bit boundary. Contiki is - still - supposed to be portable across a wide range of toolchains - therefore it i.e. intentionally doesn't use C99 features. From that perspective it seems questionable if all toolchains are able to optimize away the overhead imposed by an "unnecessary" indirection to access uip_buf - and uIP consists mostly of accesses to uip_buf. Even if the future is supposed to bring support for multiple uip_bufs which would turn the uip_buf pointer from a mere workaround to an neceesary element on can still presume that there will be targets with resources limited in a way prohibiting the use of several uip_bufs. So at least for those targets will still be a usecase for a "plain", not indirected uip_buf.
Therefore it seems reasonable to allow to stay with the "plain" uip_buf at compile-time.

adamdunkels a637ddaf4e Flush the rxfifo when turning off the radio instead of when turning it on. This seems to fix a bug that was seen in mspsim and seemed to appear on real hardware too. 2010-04-03 16:01:00 +00:00

adamdunkels 121ca946e1 Improved phase lock behaviour when neighbor is not duty cycling: senders notify receivers via the 802.15.4 pending bit that they are not duty cycling.

adamdunkels 2559e27414 API change to the announcement module: an annoucement can now be registered without a value. Such announcements are never transmitted to neighbors, until the announcement's value is set. 2010-03-25 08:49:56 +00:00

adamdunkels 7bab9316da Two major changes:
* Low-power streaming. Experimental support for a low-power mode which
  allows rapid exchange of packets with a 16% duty cycle. Does not
  seem to function correctly yet though.

* Phase locking. When the phase of a neighbor has been detected, the
  sender assumes that the neighbor will keeps it phase and does not
  send more strobes than necessary to hit the receiver's channel
  check - even if the receiver does not acknowledge the reception of
  the strobes when it should have been awake. Instead, the sender
  stops strobing and tries again at a later time.

adamdunkels 0035a70537 Reworked the locking code, which seems to fix a few bugs caused by the interaction with contikimac. Contikimac performs a CCA check in a preempting rtimer, which requires underlying code to properly call the GET_LOCK() macro. This fix seems to solve most problems, but there may be others left. 2010-03-14 22:45:20 +00:00
oliverschmidt def540e6c0 Avoid newlines in macro expansions as cc65 doesn't support them between the macro name and the open parenthesis of the arguments.
There were btw other even longer lines with expansions of the same macro already present.
