[Tinyos-help] BareSendMsg Interface
Hi all, I'm studying a source code (TOSBaseM.nc) which implements the functionality about the trasmission of data to a UART port by a micaz mote. In this code the BareSendMsg interface is used. But I yet haven't found this interface in Nesc Documentation ( see http://www.tinyos.net/tinyos-2.x/doc/nesdoc/micaz/) Is this interface belong to tinyos 1.x? Now, I'm using tinyos 2.x What's the interface can i use to replace the BareSendMsg interface?

Re: [Tinyos-help] C and nesC problems
Hi Kenneth,
I am also using T2's serial-forwarder for T1 motes. There are several
application in my company that's still using old T1.1.15.
As far as I know, you just need to modify the Serial.h to match T1
packet.

The step to compile this was :
1) Configure the sf using T2 environment (because Serial.h is generated
through autoconf)
2) Apply the patch
3) Copy BaudRate.java from T2/java/net/tinyos/packet/BaudRate.java
to your dir
4) Make...and done
The important thing is that you shouldn't run the autoconf (./configure)
once you have modified the Serial.h (The autoconf will override the patch).
Or, you can just ask me for the modified code =) It's still in BSD license
anyway.

Re: [Tinyos-help] transmission range
Radio range will depend on how close to the ground you are. The range you are describing for your mica2's seems about right for a mote on the ground. If you can put them on a pole or in a tree, you will improve your range considerably. You might also want to look at the XE1205 radio on the tinynode (from shockfish). At 30kbps we've been able to get 500m+ near the ground and near water with the whip antennae they come with. They claim that you can get 1km+ with a data rate of 1.2kbps, but tinyos doesn't currently support any data rate under 30kbps.

RE: [Tinyos-help] CC2420 packet delivery
Since the RX FIFO queue is something like 128 bytes, it would take a few packets to make it overflow. Page 33 of the CC2420 datasheet explains: The RXFIFO can only contain a maximum of 128 bytes at a given time. This may be divided between multiple frames, as long as the total number of bytes is 128 or less. If an overflow occurs in the RXFIFO, this is signalled to the microcontroller by setting the FIFO pin low while the FIFOP pin is high. Data already in the RXFIFO will not be affected by the overflow, i.e. frames already received may be read out. A SFLUSHRX command strobe is required after a RXFIFO overflow to enable reception of new data. Note that the SFLUSHRX command strobe should be issued twice to ensure that the SFD pin goes back to its idle state. And that's what the driver does. -David _ From: roberto pagliari [mailto:[EMAIL PROTECTED] Sent: Monday, September 24, 2007 10:50 PM To: David Moss Cc: tinyos-help@millennium.berkeley.edu Subject: Re: [Tinyos-help] CC2420 packet delivery Hi David, if a STXON command strobe is issued, during the receiption of a packet I'm sure the radio will transmit it. If the received bytes stay into the RXFIFO queue (is it true?) and sometime later the radio receives another packet, that would overflow, since the expected number of bytes was the previous one. What happens in that case? Does the radio flushes the RXFIFO queue? thanks On 9/18/07, David Moss [EMAIL PROTECTED] wrote: Never explicitly tried it before with the intention of noting the results, but your node should transmit, leaving the RXFIFO turned to garbage and filtered out naturally by the receive methods (i.e. checking for a proper length byte and CRC). I could be wrong, but note that having two transmitters next to each other without using clear channel assessments leaves them both transmitting and rarely receiving clean packets. If the length byte is within bounds, then the radio stack can safely download the packet and check the CRC byte regardless of what happened. If the length byte in the RX FIFO is not within bounds (smaller than expected, or larger than the RX FIFO size) then the RX FIFO certainly needs to be flushed. -David _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of roberto pagliari Sent: Tuesday, September 18, 2007 4:43 PM To: tinyos-help@Millennium.Berkeley.EDU Subject: [Tinyos-help] CC2420 packet delivery Hi All, does anyone know what happen if, during the receiption of a packet, a STXON (not STXONCCA) strobe command from the microcontroller is issued?

[Tinyos-help] Synchronisation investigation MicaZ TinyOS1.x
Hi, I'm planning on setting up an investigation into clock drift as follows: *Connect two MicaZ nodes via MIB510s to a laptop's serial ports (am getting a twin serial port adapter) *Node A transmits its clock value to node B. Node B then logs it's clock value when the message arrived *Node B then sends the value of the two clocks (A,B) over the serial port to the laptop *They swap roles and repeat. *The incoming data will be timestamped by the laptop and used to look at potential synchronisation techniques/evaluation. I'm not sure about the issue of timestamping and what variable latency will be introduced by the radio. Can people give me some hints and recommendations for this, as well as any suggestions to improve my plan? Does anyone know of applications already available that I can draw from?

On Sep 24, 2007, at 9:34 PM, Iñigo Urteaga wrote: Hi, Thanks for the appreciation. However, I still have the compiling errors related to Collection. I thought it might be useful to make a few notes about the current state of collection, because it's really the first time there's been some cross-WG collaboration and we're trying to figure out the way to handle CVS when there are some experimental extensions that look very promising. The net2 working group proposed adding a new interface to link-layer communication, based on experiences developing link estimators for collection. This interface provides the white bit, which allows a higher layer to ask if the channel had high quality during a packet. Because this would be part of the packet HIL, it's core's responsibility. So core and net2 started talking about the tradeoffs. Core agreed that it sounded like a good idea, but wanted experimental evidence that it helped before making it a HIL. In a series of experiments, net2 showed that the white bit can significantly improve link estimation. For the gory details, you can read the technical report SING-07-00, which is a draft of a submission to HotNets.[1] The short story is that, in comparison to MultihopLQI, the new CTP link estimator reduces routing cost (transmissions per packet delivered to base station) by 29% and is much more effective in sparse topologies. Based on these results, core gave the go-ahead to take the next step, which is to demonstrate that the white bit can be implemented on different radio chips and helps more than the CC2420. Incorporating the white bit involves some significant changes to CTP (the net2 collection protocol); trying to maintain a parallel CTP was seen to be too big a deal, especially given the benefits we've seen with CC2420-based platforms. So Om and Rodrigo checked in the new CTP version. The recent collection problems are due to the need to iron out some of the lingering issues. For example, since the white bit is not yet an HIL, it's not part of ActiveMessageC; this means that the link estimator needs #define statements to link to the right radio chip. If the white bit joins the HIL, then this cruft will go away. Anyways, that's the situation.

Re: [Tinyos-help] transmission range
Thank you all, I think the transmission distance is also deeply effected by the environment. I use the same mica2 433MHz at the other places, I got about 60m, and for 900MHz mica2, I got 25m, but when I put everything to that site, the distance reduced to 30 m and 10 m respectively. I think that is because the grass, the tree and river absorb the signal and made it harder to listen to each other. I never use micaz before, is 2.4GHz has less inference from the environment? I think I definitely need use a high gain antenna, but should I move to 2.4G micaz or stay with mica2? Thank you again, and I will let you know the testing results.

Re: [Tinyos-help] transmission range
In my cursory experience, the 'Zs seem to be more reliable but also more environment sensitive. The higher the freq the more line-o-sight it becomes. And 2.4G is an absorption band for water...on the other hand there are more cheap antenna options because it matches up with WiFi.

Re: [Tinyos-help] Timer and Uart0 Conflict
OK, I repeated the test while exciting the uart0 pins on the mote, and it
does lock-up. The problem is in your usage of start-edge detection i.e.
urxse : 1 in the config struct. In this case, the MCU generates a single RX
interrupt that has to be handled manually, before one can start with normal
byte receive. The current code in the stack relies on the automatic clearing
of the RX flag, thus the lock-up that you see.
