Hi all,
I played a bit around with the 802.15.4 blocks [1]. Maybe someone is
interested.
The changes are:
- It has a transceiver flow graph. (That was really easy with the new
PDU to tagged stream block)
- annotate LQI value in dict of PDUs
- CRC check
- Wireshark Connector. You can write received packets in a pcap file,
that can be read by Wireshark, which has 802.15.4 dissectors.
- and the coolest thing: the whole encoding is now done with standard
GNU Radio blocks. This includes pulse shaping and the byte to chunk to
chip to symbol mapping. It's really cool what you can do with plain GNU
Radio.
I tested interoperability it with TelosB motes. I guess it compiles only
on Linux due to the gettimeofday(?) call.
Maybe I messed up my installation as I tried the next branch and didn't
uninstall it cleanly. Now some block names are appended with '(old)'. I
hope the flow graphs work nevertheless.
Have fun,
Bastian
