RE: 回复： RE: [Tinyos-help]: how to read message from the serial port of a pc??

It's not impossible, actually I thought you're talking about megabytes of data (you could transfer megs but it would take a very long time). 20k isn't a big image, even though the data throughput is quite low with motes. All you have to do is chop the video into smaller chunks and reconstruct in the rx side. Search the list for posts about maximizing data payload size and continue from there.

	First of all, if it's a digital picture you mean by "image", a TinyOS network is far from suitable for transferring large amounts of data. If you mean a program image, there are tools that do such things. I got an impression that you haven't read the TinyOS tutorials and documentation before starting, so I suggest you start from there.

	Dear all:
	I want to transmit image via my sensor node
	the image was stored in a pc which is connectted to a telosb node, 
	so I want to install a program into the node to read image from the pc, and then tranmit it via the wsn network to another node.
	but now I don't know how to read message from a pc.
	could anyone give me some suggestion??
	thanks
	Sam
