[Tinyos-help] async/sync events preemption

Hi, I'm a little bit confused. I'm wondering, but: 1) only async events can preempt tasks? 2) async events can preempt sync commands/events? 3) therefore, sync events can't peempt task or other sync commands/events, is it? 4) but if a async function can preempt other async function where did

Re: [Tinyos-help] Can events preempt tasks?

Is the event B is doing its job inside an ISR or a lower level event called from ISR ?? OR it is trying to post a task for its job??It seems your's is the second case.I suggest you to simply toggle an LED in your event.Chalermphol Thammapalerd [EMAIL PROTECTED] wrote: Hi folks, Thanks for the

Re: [Tinyos-help] how to let mote sleep

Thanks to Phil Levis and Hui Kang (mailed me directly) for teaching me about this. To recap, the other components (except the MCU) don't sleep even if there are no tasks to run. Hence, for example, if the radio is in RX mode, I believe an interrupt would wake up the MCU if any packet is received.

[Tinyos-help] node localization using RSSI

Hi all I am doing a project which I need to localize the nodes (Micaz motes) using RSSI. How can I define some nodes as beacons (the nodes which they know their position) in such a way that mobile nodes communicate with them and also with the gateway. Is there any application similar or any code?

[Tinyos-help] question on setNoise(node, mean, variance)

Hi,I have a question about the setNoise(node, mean, variance) in TOSSIM 2.x. I found that the larger the mean is, the more noisy it is. For example, setNoise(1, -100, 5.0) can make nodes receive packets, but setNoise(1, -10, 5.0) cannot. I was expecting to see that -100 would mean more noisy that

Re: [Tinyos-help] Listen and ListenRaw

The packets without the 7E at the end might have had carriage returns or other line feed characters. This causes MATLAB to drop the line if you use fscanf(). fread() should fix that. This link should help you decipher the packets:
