GNU-Radio Clean Install
Hi everyone! I upgraded gnuradio to version 3.10 from 3.8 which seems to have broken some libraries which I can't uninstall via make because I'm missing swig. Is there a way to clean install gnuradio without any of the OOT modules? I tried "apt purge" doesn't seem to solve the problem Any help would be greatly appreciated Yotam
A Question About Gnuradio OOT Block Startup, Sleeping the Block
Hi! I am designing a message in-out OOT block that has a similar structure to the Message Strobe. It is ought to send packets as soon as the Gnuradio runtime permits. I realized that it is necessary to sleep the block off of any work for a short period of time to surpass the "block::start();" initialization. Otherwise, I am assuming, the thread is rushing an output before the Gnuradio scheduler initialization is settled therefore is breaking the runtime and forcing an exit. For now I am sleeping the block to solve the issue for an arbitrary duration, say 1000 ms. I was wondering if there is a recommended sleep duration, block specific or in general that is fixed to all blocks or calculable. Or is there a solid work around to sleeping the thread at all. I have looked for an explanation online and searched through the archives but could not find an answer. Any help would be appreciated. Thanks in advance! Brian.
Re: A Question About Gnuradio OOT Block Startup, Sleeping the Block
If your block is purely a message source, override start() and have it set an flag, e.g., a pthreads condition or Python threading.Event. The message generation portion (thread?) of your block should wait on the flag before sending anything. Otherwise, you would be sending messages out in response to work() or handle_msg() calls, which won't happen until the runtime is up and working.

HDLC block producing false packets
Hi everyone, I was using the HDLC block to receive AX25 packets of satellite signals. I noticed that the block can sometimes produce packets that are gibberish. This sounds very unlikely considering the CRC check in the block. Has anyone experienced this problem? Regards, Moses.

Hi Moses, The CRC is just a CRC-16, so getting false packets on a random input is relatively likely. I've seen this plenty of times with gr-satellites. Best, Daniel.

Re: GNU-Radio Clean Install
Hi Yotam - please state your OS and version, how gnuradio was installed, i.e., from source code or using apt, and which libaries are broken. Also, did you upgrade your OS before installing 3.10? -- Cinaed On 12/15/22 03:25, Yotam Rabin wrote: Hi everyone!

what is gateway.py
I am attempting to run a flowgraph that has a button. When the button is pressed, I get an error stating that ‘gateway.py has no attribute set_ft8button’ which is the callback for the button pressed. What is gateway.py and why is it being called? The only results I get in a search for gateway.py relate to the Gateway class in Python that appears related to an interface of some sort. I am not using anything like this. Thus, how can I correct this error? Jim -- This email has been checked for viruses by AVG antivirus software. www.avg.com
