Hi Doug, Many thanks for the help. However, I need to read the received power on every received packet, thus I guess I have to choose getPower() rather than getRssi(). Is it?
I have set the transmission power for a given packet using CC2420Packet.setPower(), thus to read the transmission power settings for the received packet, I need to use CC2420Packet.getPower(), is it? Or, getRssi() also gives a similar meanings? thanks Yusnaidi > ------------------------------ > > Message: 2 > Date: Fri, 10 Dec 2010 12:23:18 -0500 > From: Doug Carlson <[email protected]> > Subject: Re: [Tinyos-help] CTP: CC2420Packet.getPower() > To: [email protected] > Message-ID: > <[email protected]> > Content-Type: text/plain; charset="iso-8859-1" > > Yusnaidi, > See the CC2420Packet documentation ( > > http://www.tinyos.net/tinyos-2.1.0/doc/nesdoc/telosb/ihtml/tos.chips.cc2420.interfaces.CC2420Packet.html > ). > > You are looking for CC2420Packet.getRssi(). get/set power are for > transmission power, getRssi will give you the received signal strength of a > received packet (or, the RSSI of the acknowledgement for a sent packet). > > -Doug > > On Fri, Dec 10, 2010 at 11:10 AM, Yusnaidi Md Yusof <[email protected] > >wrote: > > > Hi All, > > > > I am so stucked to read the power of the received packet.
