Re: [Contiki-developers] why can't send messages using radio directly

[Niclas F. <nf...@si...>]

The Sky platform has address recognition enabled in CC2420 by default. 
This means the radio chip will drop any packets that are not broadcasts 
or addressed to the node.

You can turn off address recognition by configuring CC2420_CONF_AUTOACK 
to 0.
