Hi, thanks for this hint. I've measured the CCA check length an you're right on TelosB motes it's about 10 ms and on Iris Motes 5ms. But I can't find any value like MAX_LPL_CCA_CHECKS for the RF230 Transceiver. So I'm not able to change this interval. It seems that the MAX_LPL_CCA_CHECKS value only

when a packet is transmitted. So what's the difference between the two implementations of Low Power Listening. I thought that technique should work on both platforms. And is there a way to solve that problem? Thanks Horst Huchen ___ Tinyos-help ma

Yes, I have an application based upon SenseLightToLog (lesson 8 of tutorial) and have successfully used this for both Mica2 and MicaZ http://www.tinyos.net/tinyos-1.x/doc/tutorial/lesson8.html   I started with java net.tinyos.tools.BcastInject to read the logged data.   This was the best startin

I am trying to convert the Matchbox example (TestRemote.nc) to use the radio rather than the UART.   I converted "UARTComm as Comm" to "GenericComm as Comm" in TestRemote.ncand converted FS/Remote.nc to call SendReplyMsg.send() with TOS_BCAST_ADDR rather than TOS_UART_ADDR. I have code in the mote

[Tinyos-help] xbow MTS 310 mica2 accelerometers

2006-07-15 Thread horst
I have been advised that the maximum sample rate for the accelerometers on the MTS310 for the mica2 platform is 20 Hz (20 samples per second), but I have seen reports of usage above 200 samples per second.   Does anyone have any experience with these boards and advice on accelerometer sampling rate

[Tinyos-help] SenseLightToLog application help and advice

2006-07-08 Thread horst
I have used the SenseLightToLog application but have encountered a couple of related problems.   First, after running the BcastInject start_sensing and the motes stops sensing, the mote will not respond to BcastInject read_log until I reboot the mote. Is this failure to respond to read_log a kno
