I explain better my problem if could help anybody in the answer: I have done an application that read from a serial port USB0 in ubuntu 10.4, where there's attached IPBaseStaion the output without do nothing is this: Stable Library ========================================= Native lib Version = RXTX-2.1-7 Java lib Version = RXTX-2.1-7 RXTX Warning: Removing stale lock file. /var/lock/LCK..ttyUSB0 Packet:126 Packet:126 Packet:67 Packet:56 Packet:126 Packet:126 Packet:67 13 Packet:126 Packet:126 Packet:126 Packet:11 Packet:126 Packet:126 Packet:3 Packet:96 Packet:126 Packet:35 Packet:67 36 Packet:38
I read in the class PACKETIZER (support/sdk/java/net/tinyos/packet) this comment: To summarise the protocol: * - the two sides (A & B) are connected by a (potentially * unreliable) byte stream * * - the two sides exchange packets framed by 0x7e (SYNC_BYTE) bytes * * - each packet has the form * <packet type> <data bytes 1..n> <16-bit crc> * where the crc (see net.tinyos.util.Crc) covers the packet type * and bytes 1..n * * - bytes can be escaped by preceding them with 0x7d and their * value xored with 0x20; 0x7d and 0x7e bytes must be escaped, * 0x00 - 0x1f and 0x80-0x9f may be optionally escaped * * - There are currently 5 packet types: * P_PACKET_NO_ACK: A user-packet, with no ack required * P_PACKET_ACK: A user-packet with a prefix byte, ack * required. The receiver must send a P_ACK packet with the * prefix byte as its contents. * P_ACK: ack for a previous P_PACKET_ACK packet * P_UNKNOWN: unknown packet type received. On reception of an * unknown packet type, the receicer must send a P_UNKNOWN packet, * the first byte must be the unknown packet type. * * - Packets that are greater than a (private) MTU are silently * dropped. It means that i can discard this packet?Because i would like to know if there's a manner to read the IPv6 packet sended by the tun0 interface.I'm really confused.Thanks for any help, Daniele. 2011/5/24 daniele mattiacci <[email protected]> > Hi all, > i'm using 2 motes with blip installed:1 works like IPbasestation and he's > attached to the PC, 1 has TCPEcho application running and he's attached to > my PC. > I'm try to develop an application in Java that send IPv6 packet to a mote.I > see by console that IPBaseStation doesn't discarded the packets send by me, > but by telnet console (telnet localhost 6106) i can see that IPBAseStation > doesn't forward my IPv6 packets to a mote with address fec0::2(the > destination in the address is well setted).So what's wrong with my > application?why IPBAsestation doesn't forward the packets in the subnet at > the right mote? > > Any help will be appreciate. > Thank you in advance > Daniele. >
