[Tinyos-help] Problem with TinyECC ecc.h and Eclipse / Yeti2 plugin

2010-10-29 Thread Markus Niedermann
Hi, I want to use TinyECC in Eclipse. Where do I have to include the TinyECC-Folder that I can use it correctly? I included it in the run configurations, in the global tinyOS-Settings and in the project preferences. the plugin finds the files from ECC, but it throws me errors in ECC.h which i

Unless you have some randomisation before you transmit packets, sounds like your packets are interfering with each other. SendDone can be signaled even if packet's lost in propagation (I think..). -Original Message- From: tinyos-help-boun...@millennium.berkeley.edu

This should not be the case, as packets are only sent as a respone and after a short waiting period (20ms). Thus, the two motes can never send at the same time. Unless you have some randomisation before you transmit packets, sounds like your packets are interfering with each other. SendDone

[Tinyos-help] Broadcast packet not received by all motes

2010-10-29 Thread Simon Eberz
According to the TinyOS wiki the CC2420 radio stack, which is used by the MICAz motes, performs a CCA by default, this should not be the problem. Furthermore, not a single one out of the ~300 packets was received by the third mote, but all were received by the second one. I don't think the

[Tinyos-help] RssiDemo Mica2 RSSI to dBm

2010-10-29 Thread Correo de Wacka
HI all, I'm using RssiDemo to measure the rssi, and I'd like to convert the value of the RSSI to dBm. I've used this conversion in the java program: rssi= msg.get_rssi(); Vrssi = (3*rssi/1024); RSSI = -50*Vrssi-45.5 ; System.out.print( Power: + RSSI + dBm ); But the

[Tinyos-help] using TinyOS-2.x java sdk in Matlab

2010-10-29 Thread Chris B
hello, I was wondering whether anyone has managed to use the TinyOS-2.x java sdk within Matlab? My main motivation is to stream sensor data (magnetic,angular rate gravity) collected from wireless motes into matlab for real-time analysis (currently working with sample rates between 20Hz-50Hz).

Just an idea: maybe the third mote has some low-power radio implementation (low-power listening, LPL) enabled and the sending motes somehow do not take this into account (i.e., they do not send a long-enough preamble). Cheers, Urs On 10/29/10 3:28 PM, Simon Eberz wrote: According to the
