Re: [Tinyos-help] microsecond ftsp on TelosB without cc2420x

There is weird bug in the timestamping code in the cc2420 stack. Sometimes packets get timestamps that should be associated with a different packet. A few people tried to fix it, yet unsiccessfully. That was the primary reason why the cc2420x stack was created. Janos On Thu, Nov 15, 2012 at 10:4

hi sir/madam, I am Mahesh Geddada. I am working on iris mote. I have done successfully the measurement of RSSI with transmit power, TX_PWR_MASK=0x0F. However, when i am trying to change the TX_PWR_MASK in program, (i.e., while i'm trying to change the transmit power,,) i'm unable to change the valu

[Tinyos-help] Programming the motes in the Tesbed.

Dear All, I need some help Let say you have 20 motes on the test-bed.and you want to select 9 motes to program. How do you select them? by creating the interface where you click the motes you want to program? If you have to create the interface, how do you go about it? In need of enlig

Re: [Tinyos-help] TKN154 AMSend failure

Hi Eduardo, For a test, can you set CAP_TX_QUEUE_SIZE to 1 (in your Makefile or directly in tos/lib/mac/tkn154/TKN154.h) and see what happens? Have you tried to run your app in debug mode ("make tkn154debug", see apps/tests/tkn154/README.txt) and taken a look at the printf-output? Can you send me

Re: [Tinyos-help] help

Are you using tinyos-2.x? You should never change the TW_PWR_MASK that is describing where the transmit power bits are in a register, instead you should hange the transmit power. In tinyos-2.x you should look at the TransmitPower interface of the ActiveMessageC component. Miklos On Thu, Nov 8, 201

Re: [Tinyos-help] Programming the motes in the Tesbed.

Hi Sara, I guess you are looking for a web interface that would take care of the motes' programming. You may find helpful the Open Testbed Framework (OTF) project, in particular, maybe try to first take a look at what the testbed looks like and see if it fits your needs. http://smartcity.cs.columb

Re: [Tinyos-help] microsecond ftsp on TelosB without cc2420x

Hi, I'm aware of the timing issue in the default CC2420 stack, e.g., timestamping under heavy load as this figure shows. Consequently, FTSP is yielding up to 200 jiffies error when integrated into my protocol which generates heavy tr
