Hai..
May i know the status of 6LoWPAN implementation in the kernel.. Is it
implemented according to RFC6282/4944 ?
Right now i am testing integration of 6LoWPAN with TinyOS . When i received the
packet ,it is reaching upto 6lowpan layer but not reaching to IP Layer.
Regards,
Bhadram

Introduce new netlink attributes for SET_PHY_ATTRS:
* CSMA minimal backoff exponent
* CSMA maximal backoff exponent
* CSMA retry limit
* frame retransmission limit
The CSMA attributes shall correspond to minBE, maxBE and maxCSMABackoffs of
802.15.4, respectively. The frame retransmission shall
Replace the current u8 transmit_power in wpan_phy with s8 transmit_power.
The u8 field contained the actual tx power and a tolerance field,
which no physical radio every used. Adjust sysfs entries to keep
compatibility with userspace, give tolerances of +-1dB statically there.
This patch only adds
A documented erratum of the RF212 chip describes that some versions of
RF212 may not be properly reset by the standard reset procedure. The
described workaround seems to not fully work either; my RF212 chips will
not correctly receive any frames unless they are taken from RX mode to
TRX_OFF and bac
The current IEEE802.15.4 stack assumes that a radio will never deliver
packets with a bad CRC into the stack, as required by the standard.
at86rf230 driven radios violates this assumption because of another
incompatibility: devices are required to send ACKs if requested by a
sender, but RF2xx will
Since three of the four clear channel assesment modes make use of energy
detection, provide an API to set the energy detection threshold.
Driver support for this is available in at86rf230 for the RF212 chips.
Since for these chips the minimal energy detection threshold depends on
page and channel u
The standard describes four modes of clear channel assesment: "energy
above threshold", "carrier found", and the logical and/or of these two.
Support for CCA mode setting is included in the at86rf230 driver,
predicated for RF212 chips.

Since the AT86RF2xy chips are mostly compatible, this is only a small
change to the actual driver code. The at86rf230 driver already supports the
RF212 in most places, only three small adjustments are required:

The standard assigns channel 0 on page 2 to be 100kbps QPSK in the
868.3MHz band. Add support to the at86rf230 driver for this channel and
page, at the moment predicated only for the RF212 chip.
Per the datasheet, configurations for page 0, channels 0 to 10 and page
2, channels 0 to 10 differ only
Hi,
this patch set adds support for the RF212 radio chip to the existing
at86rf230 driver and adds support for numerous features of the RF212
chips to the ieee802154 stack. These features include CSMA parameter
configuration, transmit power control, CCA parameter configuration, and
automatic retra

This patch does multiple things:
* add .set_csma_params and .set_frame_retries for the RF212 radio.
This should work fine with RF230, but since I have no RF230 radios to
test with, RF230 does not implement these right now
* enable TX_ARET for frame retransmission limits greater than -1

This is the packet i received from TinyOS node :

I put some debug messges in the kernel the results are as follows:

Hi,
okay I will try to answer all question in this mail.
