Re: [Discuss-gnuradio] PSK31 (from audio to radio)

Hi Ron, Thank you for that tx grc graph, it is super helpful! I am just trying to get a receive work now. I am using the 6_psk.grc from the tutorial folder in the github repo you were using [1]. I have modified mine for using a hackrf on tx side and on rx side I modified to use the same

Re: [Discuss-gnuradio] Getting the Count of FFTs

Hi Marcus, That's what I'm currently doing. It's not very efficient as I have to constantly check the file size. If I can have a counter that is increments each time an FFT is written to the file by the flow graph I would be able to trigger an event based on the counter value. That was my

Re: [Discuss-gnuradio] Getting the Count of FFTs

But how would that triggering work, and what would be triggered? There's no other way than looking at the file itself to know how much has been written already; this boils down to the very Unix discussion of how atomic write() system calls should be in effect. Best regards, Marcus Am 19.

[Discuss-gnuradio] 32bit version motivations

Hi, I need a 32bit version because of this : [1] I have a W10 tablet but it is only 32bit processor, like the majority of them in this type of product [2] These tablets are very cheap and can go very fast to manage gnuradio [3] These tablets are locked and don't permit to boot from USB

[Discuss-gnuradio] Introducing gr-lora

All, I am pleased to present gr-lora, an open source OOT transceiver that is compatible with the LoRa PHY. Source code is available here: http://github.com/BastilleResearch/gr-lora As an LPWAN, LoRa is designed to provide long range and low power connectivity to embedded and "Internet of Things"

[Discuss-gnuradio] Module development and debugging

Further to some suggestions here a few months ago, I've switched gnuradio from my Windows laptop to a dedicated desktop computer running Ubuntu. It is setup in the attic with the receivers and antenna. I use my laptop and Remote Desktop Connection to run the desktop in a 'headless' fashion. So

Re: [Discuss-gnuradio] Introducing gr-lora

Matt, Very nice work. Can't wait to get home and see how many active gr-Lora are in Ohio, Atlanta and Miami. Another interesting protocol to explore is IEC 62591' Wireless Hart. Builds self define mesh network. Greg Sent from my iPad > On Sep 19, 2016, at 2:45 PM, Matt Knight

Re: [Discuss-gnuradio] 32bit version motivations

Dario, Can you send a link to the tablets in question? I'm curious what CPU is installed and how they are locked down. Building a 32-bit version would be a significant effort, not particularly because of GNURadio itself, but because of the dependencies. I'd like to see what other options there

Re: [Discuss-gnuradio] Getting the Count of FFTs

Hi Nathan, That's not quite what I want. I do not want the file to have a certain number of FFTs. I want to have a counter which is dynamically updated as the FFTs are written to a file. Ideally I want to know when a new FFT is written to the file so I can trigger another function to process it.
