433d42e170 Bugfix: if the cc2420_cca() function wasn't able to turn on the radio properly, it should turn it off again if it was off before. 2010-12-05 00:14:24 +00:00

5585d72c86 A simple but substantial change: uIP used the htons()/HTONS() macro 
functions for converting between host and network byte order. These
names are the de facto standard names for this functionality because
of the original BSD TCP/IP implementation. But they cause problems for
uIP/Contiki: some platforms define these names themselves (Mac OS,
most notably), causing compilation problems for Contiki on those
platforms.

This commit changes all htons to uip_htons instead. Same goes for
htonl, ntohs, and ntohl. All-caps versions as well.

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

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

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

e34eb54960 A work-in-progress rework of the Contiki MAC and radio layers. The 
main ideas are:

* Separates the Contiki low-layer network stack into four layers:
  network (e.g. sicslowpan / rime), Medium Access Control MAC
  (e.g. CSMA), Radio Duty Cycling RDC (e.g. ContikiMAC, X-MAC), and
  radio (e.g. cc2420).
* Introduces a new way to configure the network stack. Four #defines
  that specify what mechanism/protocol/driver to use at the four
  layers: NETSTACK_CONF_NETWORK, NETSTACK_CONF_MAC, NETSTACK_CONF_RDC,
  NETSTACK_CONF_RADIO.
* Adds a callback mechanism to inform the MAC and network layers about
  the fate of a transmitted packet: if the packet was not possible to
  transmit, the cause of the failure is reported, and if the packets
  was successfully transmitted, the number of tries before it was
  finally transmitted is reported.
* NULL-protocols at both the MAC and RDC layers: nullmac and nullrdc,
  which can be used when MAC and RDC functionality is not needed.
* Extends the radio API with three new functions that enable more
  efficient radio duty cycling protocols: channel check, pending
  packet, and receiving packet.
* New initialization mechanism, which takes advantage of the NETSTACK
  #defines.

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.

c81dbb6c89 Fixed problem with the radio driver changing transmission power to max when not specified at transmission. Also fixed bug where the lock was released when setting the transmission power. 
Thanks to Djamel Djenouri and Marcus Lundén for identifying the problem.
