Re: [Tinyos-help] Changing transmit power at run time

If I am not mistaken, CC2420Packet interface provides this feature in tinyos-2.x. You can access it using the CC2420ActiveMessageC component. Kannan. Quoting Tan, Chiang Kang [EMAIL PROTECTED]: Hi all, Does anyone know why the capability to change the transmit power of CC2420 at run

Re: [Tinyos-help] Help in Understanding Code

Hi Sumit, I believe the code is correct. The first call of the timer triggers it after a random duration. This is to keep the durations different for different nodes. But once it is triggered you repeatedly call the single shot timer with a deterministic duration. This deterministic duration will

Re: [Tinyos-help] how to convert raw LQI value?

The standard simply says that LQI has to be between 0 and 255. It does not say how it is calculated. The raw value you get from CC2420 (CORR) is between 40 and 110. A simple thing to do might be to find 'a' and 'b' such that the final value is between 0 and 255. To get a more meaningful value
