Hi Xilian,
1) Did you realize that the Xbee is based on Uart like Hauke stated? I
totally forgot that. Means that you *may* be able to use it with the
mega2560. Still, if it's not about the money or the 8-bit avr stuff I'd
recommend to use the Atmel board.
2) The board I am talking about is this one:
http://www.mouser.com/ProductDetail/Atmel/ATSAMR21-XPRO/?qs=%2fha2pyFaduinoflRfGzRdS4dlh0TRHsHwck%2fQEeul8k%3d
3) AFAIK ccn-lite is based on the old network stack which is not
maintained anymore. Doesn't mean that nobody on the mailing list could
answer specific questions. I don't now much about the latest status and
future plans of ccn-lite. As far as I see it, the old transceiver
driver for Atmel's transceiver is still in RIOT master.
Would be nice if someone with more knowledge can report about the
ccn-lite status!
Best,
Peter

Hi Peter,
Thanks for your answer and suggestion.
Regarding the Atmel sam21 board, I did some research about this
board. Are the following items are the correct choice for this board?

Please help me to confirm this if you have time.
BTW, our goal is to test ccn-lite on RIOT, so as long as the
transceiver works, ccn-lite stack should work, am I right?
Thanks,
Xili

Hi Xili,
in addition to Kaspars mail: The Arduino-mega2560 has no GPIO
implementation right now (and also no SPI). That's why there is no
transceiver support even if we have this architecure-independet
drivers. You could use other boards to drive your Xbee like stm
boards or arduino-due. They are cheaper but you need cables. (When
using arduino-due be aware of the pinout, I'm not sure if we
already managed to configure the pins so one could just plug the
Xbee shield on the board).
Regarding the Atmel sam21: Even if the status is "in progress" I
recommend that platform. It is well supported in RIOT and used by
many of our core developers. I think "in progress" means that not
all features are implemented now. But the most are, right now.
Best,
Peter

Actually, we have a Xbee transceiver hardware attached to
Arduino-mega2560. My question is that "Does RIOT has the
driver support for
some transceiver hardware (for example, Xbee transceiver)
for Arduino mega

RIOT's design has architecture-independent drivers. Xbee is
supported.
You should be able to use this combination.
That said, the network stack is in flux right now. While
link-layer
communication should work rather nice, higher layers, e.g.,
6lowpan, are
in stabilzation phase right now.
For the board "Atmel samr21 xplained pro" you recommend,
the supported
platform table
(https://github.com/RIOT-OS/RIOT/wiki/RIOT-Platforms) says
this board's support status is "In Progress". I don't know
whether we can
choose this or not.
A lot of core devs are using the samr21, so it's probably the most
supported board wrt networking.
