Hello all: I am just getting started with my TelosB motes and have a basic network up and running right now. I have a question about what I am seeing coming over the serial port I am hoping someone might be able to clear up. I have one mote with Node ID 7 programmed with the 'CntToLedsAndRfm' program. I have another mote with Node ID 1 programmed with the 'TOSBase' program connected to my PowerBook via USB. I then invoke the Serial Forwarder with: ./sf 9001 /dev/tty.usbserial-XBOQ1YGI 57600 telos & and then listen with: ./sflisten localhost 9001 I receive the following: [EMAIL PROTECTED] % ./sflisten localhost 9001 clients 1, read 83, wrote 0 04 01 08 55 ff ff ff ff 04 7d 55 02 03 00 04 01 08 56 ff ff ff ff 04 7d 56 02 03 00 04 01 08 57 ff ff ff ff 04 7d 57 02 03 00 04 01 08 58 ff ff ff ff 04 7d 58 02 03 00 04 01 08 59 ff ff ff ff 04 7d 59 02 03 00 04 01 08 5a ff ff ff ff 04 7d 5a 02 03 00 04 01 08 5b ff ff ff ff 04 7d 5b 02 03 00 04 01 08 5c ff ff ff ff 04 7d 5c 02 03 00 04 01 08 5d ff ff ff ff 04 7d 5d 02 03 00 . . <Cut to see the rollover> . 04 01 08 f9 ff ff ff ff 04 7d f9 00 07 00 04 01 08 fa ff ff ff ff 04 7d fa 00 07 00 04 01 08 fb ff ff ff ff 04 7d fb 00 07 00 04 01 08 fc ff ff ff ff 04 7d fc 00 07 00 04 01 08 fd ff ff ff ff 04 7d fd 00 07 00 04 01 08 fe ff ff ff ff 04 7d fe 00 07 00 04 01 08 ff ff ff ff ff 04 7d ff 00 07 00 04 01 08 00 ff ff ff ff 04 7d 00 01 07 00 04 01 08 01 ff ff ff ff 04 7d 01 01 07 00 04 01 08 02 ff ff ff ff 04 7d 02 01 07 00 I believe I know what some of the bytes are, but not all of them. Through experimentation, I think that byte 13 is the Node ID of the transmitting device. It also seems that bytes 4 and 11 are counting--and the sent message is a counter. So they might represent the message or some internal counter of messages? Does anyone have a definitive idea of the bytes? I have looked at the .nc files for TOSBase, but am still learning this a little, so I am not sure what I am looking for Thanks.
