|Subject:||[Discuss-gnuradio] problem of demodulation|
|Date:||Mon, 01 Dec 2008 19:58:30 -0500|
Lately, I encountered a problem with tx/rv packets by using tunnel.py script. In 2.4GHz band, there are two nodes trying to ping with each other. GNUradio node A can receive ping message but the node B can't. So I check the rx-power-log and see the power level of both nodes have similar strength. However, when I check the demodulation log file, node B cannot demodulate the message correctly cause most of the signal are below some threshold. Does anyone know why node B cannot demodulate the packets correctly?
The weird thing is when I use another node C to transmit packet to node B, B can be pinged successfully by C. So I guess the hardware of node B and the script should be normal but don't know what happen.
Any suggestions will be appreciated!
