joxe 84d969ce85 simplified the sensors API - will break some platforms... 2010-01-14 13:29:56 +00:00
nvt-se a03e899c27 Signal the result of transmissions attempts made in the mesh module. Patch from Moritz Struebe 2009-12-18 14:57:15 +00:00
nifi 7b2b93e6e6 clear transmission flag if send failed 2009-12-18 14:49:42 +00:00
zhitao 93c748cc74 Bug fix for mysterious packet loss : check FIFO pin instead of FIFOP pin for any unread RX FIFO data; 
Added protection of packet timestamp across interrupts. Note that race condition can still occur as interrupts and self-scheduled reads of the RX FIFO interleave in certain unusual patterns. More investigation is needed.

adamdunkels f4e6758b22 Use RTIMER_NOW() instead of rtimer_arch_now() 2009-12-09 18:08:26 +00:00
adamdunkels eff2203310 There were many bugs in the rtimer code, particularly one that made only one rtimer at a time work. We have a new rtimer system that we're testing, but in the meantime, I rewrote the rtimer code to explicitly support only one rtimer. Makes the code significantly simpler (and fixes a bug that was very hard to track down). 2009-12-08 23:55:17 +00:00
adamdunkels 2f105e933a Variable xmac_is_on was used both in interrupt and non-interrupt contexts and needs to be volatile 2009-12-06 23:29:38 +00:00

adamdunkels 6897270289 Bugfix to the Contiki LPP encounter timing code: encounters are now 
properly timed.
 2009-12-06 13:18:32 +00:00
adamdunkels 822149f943 Significant improvements to the Contiki X-MAC: 
* the code is simplified, particularly the duty cycling logic
* old unused code has been removed
* Contiki X-MAC now listens before sending a strobe to avoid MAC-level
  collisions
* broadcasts are sent directly, without strobes, reducing the power
  consumption of receivers
* turn off radio for 1 ms between sending a strobe and expecting the
  strobe ack
 2009-12-06 13:16:59 +00:00
adamdunkels cef2e65c9b Added an error type for signalling a MAC-layer collision 2009-12-05 21:49:51 +00:00

 2009-11-13 10:07:53 +00:00
fros4943 9b20f11cd8 chameleon returns 1 only on successful rime_output() 2009-11-13 09:14:52 +00:00
fros4943 583dd11c55 rime_output() now returns RIME_OK or RIME_ERR depending on the MAC return value.

adamdunkels 70fc23ac7e Enable stream mode by default, remove LED debug mode 2009-11-04 16:02:45 +00:00
fros4943 5f71e9914e configurable line buffer size + simplified interrupt handler + overflow check on line buffer 2009-11-02 12:47:06 +00:00
adamdunkels 5aab2eb77d A simple addition with significant performance implications: 
sicslowpan tags TCP packets with the PACKETBUF_ATTR_PACKET_TYPE_STREAM
flag, which makes the underlying power-saving MAC layer keep the radio
on for some time after transmitting the packet. This allows reply
packets to be processed directly, significantly increasing TCP latency
and throughput.
 2009-11-02 11:58:56 +00:00
adamdunkels c7a91ad4a2 Bugfix: UIP_TCP_BUF -> BUF 2009-10-27 23:09:58 +00:00
adamdunkels 631af06c7c Bugfix: Active TCP connections in uIP are made by first setting up the 
TCP connection state, then poll uIP to send out the first SYN. Until
now, however, the SYN was not sent as part of the poll, but at the
first retransmission. This is now fixed.
 2009-10-27 22:34:08 +00:00

adamdunkels 9ec57d61ad Added MAC layer framing support to X-MAC so that packets now are standard 802.15.4 frames 2009-10-19 20:53:56 +00:00
adamdunkels 4de1816e36 Added a new module called "framer" that creates MAC level frames to 
the packetbuf from packet attributes. Two framer modules are included,
one that creates 802.15.4 frame headers, and one that creates a
minimal "nullmac"-style header that only contains the link-local
addresses.

adamdunkels fb037e0afb Added function for sending an UDP packet to a specified IP address and port number over an existing UDP connection 2009-10-18 22:02:01 +00:00
adamdunkels 9d26bd663e A new optimization to X-MAC: senders now keep track of when neighbors 
last were known to be awake. When sending a packet, a sender does not
start to send strobes until the neighbor is expected to be awake. This
reduces power consumption for senders and decreases the contention in
the network as there are less packets in the air. Additionally, the
ACK optimization was improved so that data/ack exchanges now are
more efficient.
 2009-10-18 13:19:25 +00:00
