    I'm trying to communicate two msp430 + CC1120 to eurpea frequency. I have tried in the American band and it works. But, to use the European "FHSS_ETSI_50 1" in the file cc11xx.c. and then I have no Connection

      If you navigate to :
      Conttiki> Examples > Sky ,
      you can see some examples which are programmed on the sky mote
      If you open one of them e.g radio-test.c we can see:
      include "cc2420.h"
      so the specification of sky mote device is include in:
      contiki > dev> cc2420
      now you can see the source code, and check if the code are clear enough to
      be exchanged by your own specification or not.. and the whether the COOJA
      can run the changed mote or not

      Good Luck,

      Cooja: How to modify cooja nodes features?


      I have to implement a WSN and based on wake-up radios and measure power
      But i have my own physical nodes, with my own HW which is different from
      the nodes that are avaible in Cooja. I would like to modify the key
      features of one of theese nodes, for example, the Sky Mote, in order to
      implement my parameters.
      I use IEEE 802.15.4 by Zigbee (ETRX2), an ADuc841 microcontroller (62kB
      Flash Memory, 2kB RAM) and also a FPGA Xilinx Spartan 3 XC3S200.
      Is there any way to simulate the characteristics of my node and implements
      them in Cooja?
      Maybe creating my own Cooja node or modifying one.

    Hello, I'm doing some research on the contiki OS and I'm interested to use some features of the Powertrace, I need to find at the basestation ( or the sink node) 3 variables.
    1- Packet drop rate
    2- noise power of the motes
    3- signal power of the motes

    OR the SNR of the sending mote to the sink.
    anyone can help me please in that, Thanks in advance



    I am working with operative system CONTIKI 3.0 with cooja and I am new to this.

    I need to get ETX metrics of each node sky on the routes of net and to use that information in the objetive function. for simulation

    I appreciate any help
