adamdunkels b98f7d891f Bugfix: added missing queuebuf allocation 2010-02-06 20:50:24 +00:00
adamdunkels 671216c558 No need to clear the headers now that we explicitly save a queuebuf when sending fragments 2010-02-06 17:07:43 +00:00
adamdunkels b6647b5630 Turns out that with cxmac, clearing the header after sending a packet is not enough to make fragmentation work. Instead, we allocate a queuebuf and restore the packet after from the queuebuf after sending it. 2010-02-06 09:42:49 +00:00
adamdunkels 494e692d0b Bugfix: clear the header after sending a packet solves a problem with fragmentation; also prod the watchdog since fragment transmissions can take a long time with some low-power MAC protocol 2010-02-06 07:49:58 +00:00
adamdunkels a68b4c40c4 Added a function to clear only the header part of the packetbuf 2010-02-06 07:48:52 +00:00

adamdunkels 4bffd277f5 Don't set the stream bit on outgoing TCP packets for now - it doesn't seem to play well with IPv6 and X-MAC 2010-02-03 16:44:19 +00:00

adamdunkels 4bc4f033e8 Increase the trickle resend interval for router advertisements 2010-02-03 01:13:17 +00:00
adamdunkels 181213124b Added a configuration option for setting the MAC channel check rate (which must be a power of two). The configuration is independent of the MAC protocol. 2010-02-02 23:28:58 +00:00
adamdunkels f66cd6d44e Increased the forwarding queue to six packets to improve collection robustness 2010-02-02 21:44:05 +00:00

oliverschmidt 3f142f0718 Convert '@' correctly from PETSCII to ASCII - by leaving it alone. 2010-01-31 23:46:19 +00:00
adamdunkels 1a13d25d33 Revised version of the X-MAC implementation that uses a ctimer instead 
of an rtimer for the periodic radio duty cycling. The benefit of this
implementation is that it leaves an rtimer free for user tasks. The
drawback is a slightly higher idle power consumption. This new version
is based on the current rtimer-based X-MAC.

adamdunkels 0b58ca3b22 Bugfix: split full size TCP segments if they match the MSS definition, not only the buffer size definition 2010-01-25 13:53:15 +00:00
adamdunkels 7615a6cf47 Bugfix by Henrik Mäkitaavola: check that ICMP6 process is defined before invoking it 2010-01-25 13:37:05 +00:00
adamdunkels 4f3e8d565c Added a simple CSMA (Carrier Sense Multiple Access) mechanism that 
works on top of an underlying duty cycling mechanism. The CSMA layer
retransmits packets that could not be sent because of a collision was
detected.
 2010-01-25 11:46:44 +00:00
adamdunkels 7ad93e5d18 Added a field to the struct mac interface: 
channel_check_interval(). This function returns the interval by which
the duty cycling mechanism checks the radio channel for activity. It
is used by higher layer mechanisms to determine suitable timeouts for
retransmissions.

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.
 2009-12-11 18:32:54 +00:00
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

fros4943 0034fd7bca generic return values for sent packet 2009-11-13 10:09:02 +00:00
fros4943 9cc57c4324 generic radio return values

 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. 
this patch may affect Rime sniffers running on top of MAC protocols that do not yet return generic MAC return values
 2009-11-13 09:10:24 +00:00

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.
