Hi Josh,
I have done the same work as Alex. I modified the code in
gr_message_source. I added a tx_sob tag and a tx_time tag to the first
byte of the message, and a tx_eob tag to the last byte of the message.
Assuming:
1. there are 100 bytes in a message(or we call it a packet)
2. bpsk modulation i

Late packets get dropped. Think of this as a catch-up mechanism.
Otherwise, all subsequent packets would also be late.
The late packet error follows the same policy as the

Hi Josh,
The "late" packet gets sent anyway. Right? At least I have verified this at the
receive side. Further, I hope that one L is printed for each "late" burst
(i.e., no. of L's equals no. of late "bursts"). Correct? Finally, how can one
print the metadata to find which of the bursts were la

All,
I have an application where I need to send timed-bursts, so, I have
modified tags_demo.cc a bit according to my needs. Now, when I run the
transmitter flow-graph in order to send timed-bursts, I occasionally see a
sequence of "L..." in the console. I assume it is some sort of error

Hi,

As 3.6 brings in a new build system, I decided to give it a go on the
AIS module. I based everything on gr-howto-write-a-block
I can build and install everything, here is what get installed:

Hello,
I am working on a C++ block which will call the set_center_freq method
of a uhd_usrp_source or uhs_usrp_sink passed to the block with a

so from an identity standpoint it really doesn't matter which one is

Hi all,
CGRAN has grown significantly beyond my expectations over the past 4 years!
It started off as two personal projects with the hope of providing
somewhere for people to develop applications outside of the main GNU Radio

Dear Stefano,
Thank you for your guidance - I realized I downloaded the binary version of
GNURadio from apt-get, which did not come with the folder gnuradio-core.
After installing GNURadio from source I managed to find the corresponding
C++ file.
