Thanks for you attention, Michael, In fact, What I want to do is just send a .txt file from the PC to a node via the UART, then the node transfer it to a remote node via RF. Do you help any code for this implementation, or could you tell me some link to get this demo?? thanks Sam
Michael Schippling <[EMAIL PROTECTED]> 写道： If I understand correctly, your TOSBase mote is flashing LEDs when you try to send a message so that means that your baud rate and such are probably correct on the PC side. But your re-Mote is not receiving anything... It's possible that SimpleCmd expects to get a message to a specific moteID, I'd have to go look through all the code... See if you can get it to accept a message with a BCAST address. Have you had these devices successfully using the radio at all? You might try something a little simpler like CntToRfm to see if you get any communication. And make sure you've compiled all the programs with the same radio channel defined. I don't know why adding TimerC to the TOSBase config is troublesome. I have done just that for mica2's to add some bit twiddling outputs to my base-station. What is the actual error message you get? But adding new radio code is probably a recipe for disaster since TOSBase uses a bunch of lower level functions to do it's magic, so I'd just leave it well enough alone. I think what you see in RadioSend is the initial byte send, subsequent bytes get sent from an interrupt routine somewhere else in the code there.
