adamdunkels cea299d79a Call upper layers even if packet reception failed - this allows the RDC layer to shut off the radio even if a malformed packet was received. 2011-01-09 21:09:28 +00:00
dak664 8b5577eca2 Patch from Roger Larsson to answer mac address request, for testing autoconfigure. 2010-12-23 22:38:47 +00:00

adamdunkels 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
adamdunkels 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.

adamdunkels 3fa8ffda1a Moved the modules packetbuf, queuebuf, and packetqueue from net/rime to net/, since they are not Rime-specific 2010-06-14 19:19:16 +00:00
nifi 14b1bb9f57 Fixed to only use leds when DEBUG is set 2010-04-20 11:41:16 +00:00
adamdunkels 3670fac618 Bugfix: timing fixed 2010-04-08 18:23:24 +00:00
adamdunkels 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
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 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
adamdunkels 4d5f112960 New return value for invidating a link-layer collision 2010-03-30 23:00:22 +00:00
adamdunkels 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
adamdunkels a3a8c0e179 Safety check: only try to read a packet if it was preceeded by an interrupt (which sets the pending flag) 2010-03-19 13:18:53 +00:00
nifi ea090a60e6 Fixed to call the SLIP callback function also when using IPv6 2010-03-17 07:10:25 +00:00
adamdunkels 67b0170a43 Bugfix: don't care about FIFOP when reading a packet; if the radio rx had been turned off before a packet was read, FIFOP would be zero and the packet would be trashed 2010-03-16 18:10:09 +00:00
nifi 55e0fec37e * Changed to write keys to CC2420 RAM big-endian order 
* Fixed cc2420_aes_cipher() to wait for encryption to finish before reading result
 2010-03-15 23:04:54 +00:00
nifi e834562455 * Fixed FASTSPI_READ_RAM_LE to wait for tx end before reading 
* Added FASTSPI_WRITE_RAM_BE to write to RAM (big-endian order)

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
nifi 58c55340ed fixed to work with IPv6 2010-03-10 22:30:39 +00:00

adamdunkels cc7d3ae142 Reset CCA mode to default. Make sure that the radio gto switched on when reading RSSI; otherwise node will reboot because of watchdog 2010-03-09 13:18:16 +00:00
adamdunkels b9827d2b36 Bugfix: didn't correctly reset the pending flag when a packet was read from the radio 2010-02-25 16:06:44 +00:00
adamdunkels 4b04fdd328 Minor style fix 2010-02-23 18:26:26 +00:00
adamdunkels 1ee32c3074 Removed non-functional time synchronization code; added some experimental code for CCA checks (enabled CCA mode 1, a temporary development function for setting the CCA threshold); enable the possibility to switch off radio even if a packet is currently arriving 2010-02-23 18:24:49 +00:00
adamdunkels 5292005962 A null radio driver that does not do anything - useful in the native port and as a template for new radio drivers 2010-02-23 18:18:53 +00:00
adamdunkels 0b2b7bcdba Removed inadvertedly left-over include file 2010-02-18 23:52:34 +00:00
adamdunkels 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.
