Do you have good reasoning why BT-LE for example should not be work undertaken by the 6lowpan WG? 6lowpan is not air-interface specific,. Your comments are anyway redundant since the WG decided at IETF80 to take on the work of specifying IPv6 over BT-LE. -Raj > > > As such, it would probably be better to look for other ways such as a >BoF. >6lowpan over Bluetooth seems to fall into this category as well :-). > >My 2 cents. > >Behcet > >> Hi Alex >> >> Let me try to answer... >> >> There is a well defined reliable data transport (DPRS) specification >>for >>packet traffic.
