[Tinyos-help] 2.0.2 Snooping

[David Moss]

The main improvements are the ability to control auto-acknowledgements
(defining either hardware or software acks) and address recognition using
preprocessor variables or at runtime - instead of manually editing
CC2420ControlC to make the radio do what you want.

To remove all acknowledgements, #define (or use CC2420Config in 2.0.2)
  CC2420_NO_ACKNOWLEDGEMENTS
  
To use hardware auto-acks instead of software acks, #define:
  CC2420_HW_ACKNOWLEDGEMENTS

To stop using address recognition on the radio hardware, #define:
  CC2420_NO_ADDRESS_RECOGNITION


* Added two methods to enable/disable automatic address recognition:
  - Preprocessor CC2420_NO_ADDRESS_RECOGNITION to disable address
recognition at compile time
  - CC2420Config.setAddressRecognition(bool on) through CC2420ControlC


You can configure the behavior of your snooping nodes based on which options
you set for acks and address recognition.

Subject: [Tinyos-help] 2.0.2 Snooping

I have a heavily modified version of MultihopOscilloscope for tmote  
sky with TOS 2.0.1 that uses CTP but needs neighboring nodes to snoop  
information transmitted to the base station. To get this to work in  
2.0.1 I disable the chip's address decoding. I tried the same code  
after installing the stock 2.0.2 (no disable) and it doesn't work. My  
question is: what are the specific improvements for snooping with  
cc2420 in 2.0.2 (I read the update in the tos/chips/cc2420 but nothing  
about snooping)

Thanks in advance
Wes
