[Tinyos-help] Read the RSSI in the TOS_Msg
Hy, I'm trying to read the RSSI value in the packet that arriving at the base station, but I don't understand something: of course I can't put the value from the node that send the packet (it doesn't know how much will be the value at the base station!!), also I have to modify the TOSBase application for read the RSSI from the chip CC2420 of the node that runs like base station? I tried to insert the field "Strenght" in the AM.h file, but it seems that nothing happens. Any help it will be good. Thanks.

[Tinyos-help] tmote baud rate
Title: Message It seems that the uartbaud rate on the micaz's (57600) is much faster than the tmotes - I'm not sure what the tmote's baud rate is. But I do notice a significant different between the UART speeds on the two motes. Is there a way to jack up the baud rate on these tmote's?

For my research, I thought it would be nice to run some performance comparisons (using various metrics) between the protocols I have implemented and a protocol that comes standard with TinyOS. However, since there are several routing protocols that come standard with TinyOS, I'm not sure which one to pick. For instance, below are the locations for several protocols found in TinyOS: - tos/lib/Route - tos/lib/MintRoute - tos/lib/MultiHopLQI I was wondering if anyone had any thoughts on which one of these protocols to use in my simulations/comparisons? Ideally, I want to select the protocol that a researcher who was deploying a sensor network would be more likely to choose. Out of the existing sensor network deployments, which routing protocol seems to get the most use?

Re: [Tinyos-help] mica2 pcb files
The design is based off the Mica design, but was done by Crossbow in collaboration with UCB. When the design was finalized, Crossbow started to produce it, but UCB never got the source files to the design (unfortunately). Someone from Xbow should chime in, but I believe that this is part of their intellectual property package? Bottom line is that if you want the design files (gerbers), you'll have to ask someone at Xbow. -Joe On 12/1/05, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: Hi all, Can anyone tell me who first made the Mica2: Berkeley, Crossbow or someone else?

[Tinyos-help] CC2420 MAC modification
Hi, Thanks to all who replied earlier to my question about modifying the CC2420 MAC. After reading the relevant parts of the data sheet, most of my questions have been answered. I am still concerned about one thing. I was interested in sending short impulses about one CC2420_SYMBOL_UNIT long. From the data sheet, the shortest packet I could transfer is 7 bytes (4 bytes preamble, 1 byte SFD, 1 byte length) long. Is there any way I could send even smaller packets. The un-buffered serial mode looks promising, but even there it seems the preamble is attached by the hardware, so it is not possible to send smaller packets.
