Hi all,
I am a newbie at GNU Radio, and I am in the beginning of my bachelor's
thesis, which is to connect GNU Radio with Telosb sensor node. I know there
is a project named UCLA_ZIGBEE_PHY to connect GNU Radio with Zigbee, so i
try to use this code to do some implementation.
Currently i use XCVR2450 Rx daugtherbroad in USRP. I installed a simple
application in telosb, and when i type the command: python cc2420_rxtest.py
-c 2480000000(Telosb uses channel 26, and it's central frequency is 2.48G).
I get the following result:
cordic_freq = 2.48G
data_rate = 2M
samples_per_symbol = 2
usrp_decim = 16
fs = 4M
Using RX d'board A: XCVR2450 Rx
>>> gr_fir_fff: using SSE
802_15_4_pkt: waiting for packet
There's nothing more to display. So i was wondering whether GNU Radio can
communicate with Telosb?
I check some file in UCLA_ZIGBEE_PHY project, and in
ucla_ieee802_15_4_packet_sink.h:
static const int MSG_LEN_POS = 8+1; // 8 byte sos header, 1
byte AM type
static const int MAX_PKT_LEN = 128 - MSG_LEN_POS - 1; // remove
header and CRC
I don't think this definiton is compatible with ieee802.15.4 frame format,
whose FCF is 2Bytes. Maybe the different frame format definition is the
problem. I am not sure.
Is there any guideline available to get GNU Radio communicated with Telosb?
Any help is appreciated!
Thank you very much!
Regards,
You Lizhao
