Re: [Discuss-gnuradio] FTW IEEE802.11a/g/p OFDM Frame Encoder

Thanks for quick reply.

I did that before already. Nothing changed now also. 
All work, but do not transmit regularly. In ofdm_tx. smt. is being transmitted for a sec then the led A turns of again. 

I run demo.sh also. I see the plot and wireshark, but again as I say nothing is being transmitted.

did the rx/tx flow graphs work now, or did you just switch to the transceiver?

The transceiver connects itself through a tun/tap device to the Linux TCP/IP stack. To get this running you should know a bit about IP and MAC addresses.
There is also a startup script in the apps folder that should show how to start things up.
