[Discuss-gnuradio] gr-osmosdr module disabled

2012-06-15 Thread Phil
Thank you for reading this. I have progressed a little since my last batch of pleas for help. Does the following look correct? Also, there is no mention under "sources" of osmocom in gnuradio_companion. I'm trying to use my Ezcap dongle with Gnuradio. -- checking for module 'libosmosdr' --

Re: [Discuss-gnuradio] Patch to Include LNA enhancement and IF gain and filter settings for FCD

2012-06-15 Thread Alexandru Csete
Okay, I'm going to agree to include the extra API; however, before the patch can be applied corrections are necessary. In most functions you will have to either reverse the inequality sign or the order of the conditions for the parameters to have any effect. Also note that you have a gap for the IF

42 is the length of the ARP request and make sure the other side sends out ARP reply, otherwise, the Ping will always fail due to routing issue. On Fri, Jun 15, 2012 at 9:31 AM, Weixian Zhou wrote: > I am doing test with tunnel.py and following the readme instructions > located gnuradio/gr-digit
