[Tinyos-help] using Packet Link interface in TinyOS 2.0.2.2

[David Moss]

The Packet Link layer has only been implemented in the CC2420 stack, and not
any other radio (although it could work on other radios rather easily).

 

So for now, yes - you should wire directly to the CC2420ActiveMessageC
interface.

Subject: [Tinyos-help] using Packet Link interface in TinyOS 2.0.2.2

 

Hi All,
 I was trying to use the Packet Link interface in TinyOS 2.0.2.2 release. I
read in TEP 127 that you could use the Packet link interface to set the max
number of retries and the retry delay. However in the CC2420 stack although
the CC2420ActiveMessageC  component exposes the PacketLink implementation it
is not exposed further in the ActiveMessageC component in the platform
specific files ( in my case telosa). 

Does that mean in order to use the PacketLink interface I will require to
directly wire into the CC2420ActiveMessageC interface instead of the
platform specific ActiveMessageC component ? Am I missing something over
here ? Shouldn't the ActiveMessageC component in the telosa also expose this
interface.? Or is this because currently the PacketLink interface is very
specific to CC2420 (TEP 127)? 

regards,
Avinash
