Ofdm_mod / FTW ofdm: Problem sending a sequence of frames

GNU Radio

Hi,

im working on a projekt using the Cgran Project FTW IEEE802.11 OFDM
frame
encoder.
https://www.cgran.org/wiki/ftw80211ofdmtx

I use Ubuntu 10.04, Gnuradio 3.2.2 and a USRP2 with 2450 tranciever

I have modified the “get_info” function in the ofdm_package_utils.py
file
and the optionparser to create different types of 802.11g frames.
My goal is to send a sequence of frames with a shorter delay between the
frames as if i start the script for every frame.

I have created 4 ofdm_mod objects, one for every frame.

So here is my Question:
is it possible to change the self.connect(tx_path, self.amp, self) while
executing the top block to conntect the objects and send_pkt() in a
loop (
in file: ftw_ofdm)

or is this the wrong way to send more than one frame?
and when is the “send_pkt(eof= True)” needed? after every frame or after
the
whole seqence?

Thx for your help :slight_smile:
Hans
