be117afe04 After a lot of tweaking and twiddling with the timing of the ContikiMAC code and the mechanisms in the CC2420 driver, things seem to work somewhat stable now - knock on wood! 2010-04-04 07:49:30 +00:00

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

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. Neighbors then will start sending packets immediately and not wait for neighbors' phase. Tweaking of ContikiMAC timers to make it more reliable. 2010-04-03 13:28:30 +00:00

a8d8b6d31d Improved parent management: parent neighbor is retained until a better neighbor is found (with 1 ETX less than parent). Don't drop parent neighbors when loop is detected (loops are transient anyway). 2010-04-01 10:45:21 +00:00

add426de4b Bugfixed stream mode: node listens 100% for 0.5 seconds in stream mode. Naming change: is_listening changed is_snooping. 2010-04-01 10:02:04 +00:00

c9ca5d61e2 Rewrote the pending_packet() function to check the FIFOP pin instead of the 'pending' variable - works must better on real hardware and is now supported by the latest mspsim 2010-03-31 19:08:56 +00:00

bcfa80102d Had previously not included the waiting time that the CC2420 introduces when sending a packet. Also increased the smallest packet size, just to be on the safe side. 2010-03-30 23:01:32 +00:00

5e7f99a2c0 Reverted the removal of the code that checked the FIFOP pin before reading a packet - checking FIFOP is the correct way to do it. Also added TXONCCA for now, including new radio.h return values to indicate a link-layer collision. 2010-03-30 23:00:05 +00:00

9508d2c4d7 * Added configurable default number of transmissions for CSMA to use when not specified using packetbuf attributes (CSMA_CONF_MAX_MAC_TRANSMISSIONS).
* Renamed packetbuf attribute PACKETBUF_ATTR_MAX_MAC_REXMIT to PACKETBUF_ATTR_MAX_MAC_TRANSMISSIONS where value 0 (attribute not set) means that default number of transmissions should be used.

a4f9e62295 Added a parameter to collect_open() that specifies whether or not the node should be a router for packets, or only an originator of packets. Updated the collect module to the new annoucement API. 2010-03-25 08:51:07 +00:00

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

4d68bdf74b Bugfix and addition by Dogan Yazar: psock_readbuf() shouldn't wait for a full buffer (which might never happen); a new function for sending strings that batches data and sends full buffers instead of individual strings. 2010-03-24 21:03:32 +00:00
