title: is there any 802.15.4 RF module (6LoWPAN) for Arduino
body: <p>I want to make communications between an Arduino and a laptop with the protocol stack 802.15.4-6LoWPAN-IPv6-UDP. I notice that there are some 802.15.4 RF module for Arduino, but almost all of them work with ZigBee. Is there any 802.15.4 RF module for Arduino supporting 6LoWPAN? </p>
  
  <p>Also, I could not find a 802.15.4 dongle (with 6LoWPAN support) for the ubuntu laptop. Any suggestions to make ubuntu be able to send packet through 802.15.4-6LoWPAN?</p>
