First there comes the ethernet header, including Preamble, SFD and Type (0x9021). Then, as far as I understand right now, it's followed by RTmac-Type (0x0001 for TDMA), Version 0x02, Flag (LSB=0). Then TDMA-Version 0x0201 and Frame ID (which one for data?) and the payload itself. So my Question is, which Frame ID is used for data? Or if the data is just following after the Flag-Byte, what is be done if the payload starts with 0x02010000.........0? How does the receiver know that there is now pure data coming? I can't find a real information in the spec. Thanks a lot Karl -- von Karl Reichert "Feel free" - 10 GB Mailbox, 100 FreeSMS/Monat ...
