[Discuss-gnuradio] Issue with tuntap_pdu

2014-11-06 Thread Jonathan Fox

Now the clock runs fine (with gr::block::nitems_read). But I have another problem: I have a rate of 10.23 million samples per second and I need to delay the signal +-1ns. With the modified block delay (controlled by an input) I can delay the signal 97.75ns (1 / 10,230,000 -> + - one sample). Cou

I think yes. Rest of 802.11 beacon in my area also have CRC (while in monitor mode - Windows Network Monitor). -- View this message in context: http://gnuradio.4.n7.nabble.com/802-11-Beacon-frame-transmitter-mobile-devices-tp51215p51217.html Sent from the GnuRadio mailing list archive at Nabble

Can't remember exactly but is there some form of CRC checking with the beacon? Because in monitor mode, CRC checking is typically disabled. R > -Original Message- > From: discuss-gnuradio-bounces+ruben.merz=swisscom@gnu.org > [mailto:discuss-gnuradio-bounces+ruben.merz=swisscom@gn
