[Tinyos-help] Small useful Tos-bsl change

Can someone help me with python? The problem for me is that the tool tos-bsl is written in python, which is one I cannot use, but I need to add a change in a script. The tool accepts comport as number in win/cygwin, starting from 0 which is COM1. I wish to avoid using numbers and instead use

[Tinyos-help] need help for developing a protocol based on CSMA

Currently, I am developing a Body Sensor Network(BSN) plantform which is quite similar to Telos platform. It requires to develop a program based on the CSMA/CA protocol. The hardware configuration is shown as follows: CPU: TI MSP430F149 Radio Transceiver:Chipcon CC2420 nbsp;I am not sure

[Tinyos-help] How much time TX,RX in Micaz?

Dear all, I am wondering about how much time does the transceiver take for transmitting and receiving a packet, let's say of 127 bytes? Thanks very much Daniele Daniele Munaretto Researcher DoCoMo Communications Laboratories Europe GmbH Landsbergerstraße 312 80687 Munich Germany

[Tinyos-help] Problem with TinyOS 2 Collection in tutorial 12

Hi, I have been trying to get the Collection-example in tutorial 12 to work without success. Problem is that the root-node doesn't receive messages from other nodes. I'm using Mica2 and currently I've tested with three nodes in different roles. The hardware should be ok as the examples

RE: [Tinyos-help] The power consumed

How do you deal with the huge changes in current (10 milliamps to 10 microamps), or deal with the corresponding large jumps in voltage at the oscilloscope/voltmeter? With an oscilloscope that can manage two millivolts per division, and a 220 ohm sense resistor, 10 microamps should give you a 2 mV

[Tinyos-help] segmentation fault in msp430-gcc 3.2.3 compiler [fix]

Hi, I stumbled upon an internal compiler bug of the msp430-gcc 3.2.3. I built the compiler using the build-mspgcc script (TinyOS-1.x). This bug is also present in the msp430-tools RPMs available for download. A single-line change should fix the bug. Not knowing to whom this issue might be of

[Tinyos-help] nested events

Hi All, I want to insert the received event inside the timer.fire()! The compiler will complain of the nested events... but I am really need something like this: .. event void AMControl.startDone(error_t err) { if (err == SUCCESS ) { call Timer1.startOneShot( 2000); // only once I

[Tinyos-help] Install on Mac OS

Some people have been expressing concerns recently on not getting tinyos to work properly under Mac OS. I wanted to point them all again to a tutorial I wrote about a year ago. Everyone I've heard from has had success with using it, so hopefully you will too. I updated and tested it again last

[Tinyos-help] a very rare serial write failed event on telosb

Hi All, I am using TelosB motes running theTOS 2.0.1. I installed the BaseStation app and started SerialForwarder to start writing to the mote. In all the cases the writes were successful and the only write failure was when I tried hogging the mote with the writes. The writes would continue

[Tinyos-help] Setting channel to 26 does not work

Hello, I've been running some tests on changing the channel of the radio. Whenever I change the channel to 26, the receiver doesn't receive any packets. All other channels work except for 26. I used a packet sniffer to check if the transmitter was transmitting on channel 26 and it was. I tried

RE: [Tinyos-help] The power consumed

Hi, I used 2 different R (1ohm and 25ohm) with large delay between sending/receiving packets (around 30s). Since there are spikes (even in the sleep mode), I use oscilloscope's average value. Thus, to get the whole current consumption, I measured the sleeping current first (using 25ohm).

re: [Tinyos-help] unsuccesful attempt at mesh networking (MultihopOscillator)

Hi, What version of TinyOS that you use ? I've done the same thing in T2.0.1, and it worked fine. Here's how I test it : 1) Put node 0 and node 2 out of range 2) Put node 1 in the middle (in range for node 0 and node 2) 3) Test multihop by turn on/off node 1 The problem with your test method

[Tinyos-help] Query: TX timing randomness in multihopping???

Hi, I am trying to implement a true mesh routing. I have finished implementing an elementary routing layer above the ActiveMessage layer. But I am facing a lot of packet drops. This I guess is due to collision. I added the packetacknowledgements to solve the problem but still the case is same. I

[Tinyos-help] need help regarding tinyos

Dear All, we are developing a mobile sensor network. we have a problem regarding storing retrieving data from the mote. we thought this can be achieved by writing to EEPROM (Logger) and retrieving from it due to the memory constrain. is this the way to do it or is there any other methods you
