Hi All,
I've been trying to run some hardware tests between two USRP2s, but I have
had no success in receiving packets. I am using the modified TX from Tiago.
I feel sorta confident that the TX code works, because when I run the
usrp2_fft.py, I see a wave form being transmitted over the channel.
Hi Colby!
We have also tried without success.
We have used the TX path from Tiago and a modified version of the RX path
(firmware and FPGA at their latest update).
I also felt confident that the the TX path works, and consequently that the RX
path had some problem.
So we have tried to transmit

Hi,
I am new to USRP.
Would like to know about where can we access PCB files or gerber files for
USRP1 USRP2?
Are we allowed to make modifications to the hardware as per the requirement
changes...!! What are the licences applicable for hardware development.
Pl advice.
Thanks,
Sudhir.
That's good news.
The code I sent seemed to be working but i realy didn't tested it. We have
only one USRP2 here and we were trying to receive pkts using a 802.11b PCI
card (Realtek RTL8180L chipset), but without success (some problems with the
card configuration).

I'm trying to modify the bbn_80211b_rx.py code inorder to receive
packets but in every step I'm facing an AttributeError like:
AttributeError: 'usrp2_source_32fc_sptr' object has no attribute
'make_format'
AttributeError: 'usrp2_source_32fc_sptr' object has no attribute
'set_format'

Hi Ben,
I uploaded my files to the usrp2_version in the CGRAN server. It uses the
same files I used to run my USRP2 tests, so it should interface with the
hardware correctly. Let me know if it does not.
Bests,
Colby

Hi All,
So I ran a sanity test on the TX and RX functions.
In the tx.py file, I added a file sink to record the data being sent to the
USRP2. In the rx.py file I added a file source to read that data, rather
than reading samples from the USRP2. When I did this, it was able to

It appears this was an inadvertent consequence of the change in the
