It should not be caused by sensor data but UART transmission. You can first check whether the data length field in the packet is correct or not. On 4/18/08, Maria Taramigkou [EMAIL PROTECTED] wrote: Hello!!! I have loaded the Oscilloscope and TOSBase applications on 2 motes..I execute the

Try using ListenRaw to see what you are really getting. One possibility is that Listen is expecting a different TOS_Msg format than the one being received. This is flagged in the MOTECOM variable, e.g.: [EMAIL PROTECTED]:tmote and [EMAIL PROTECTED]:mica2 will use different AM headers... MS

You didn't really tell us enough information. What motes, what other hardware, what version of Tinyos? On Fri, Apr 18, 2008 at 6:53 PM, Maria Taramigkou [EMAIL PROTECTED] wrote: Hello!!! I have loaded the Oscilloscope and TOSBase applications on 2 motes..I execute the Listen.java and the

Hi all... I have come with an idea of the origin of the faulty behaviour of my experiment... To simplify I will illustrate it with two dimmers: they are connected to the wall sockets and to the motes, and the motes are connected per USB to a HUB which is also connected to a wall socket and to

Joe, yeah, my configuration is as follows: I have 10 motes, five of them are connected to the inverter/amplifier/dimmer group. This means I need three hubs, each of them with four usb outputs. For this experiment only these 5 motes are connected, and my hub configuration is as follows: All

When you program your motes, have you programmed them with different node ids like make tmote reinstall,NODE_ID? - Dongyan On 7/6/06, Jose L. Ponce [EMAIL PROTECTED] wrote: Hello all, My question is very simple: I have 5 motes with the same program installed. This program receives an

Yeah, I do that. I think it's an electrical problem: The motes are connected with USB cables to USB hubs, which are connected with each other, to the power and to the computer If I order one node to give the maximum output and there are 2 nodes connected, each gives 1/2 of the maximum output,
