Re: Transmitting is finished Sooner than promised, How I can compute the time of transmitting for a file that is set to no-repeat

Hello stackprogrammer: HackRF does not support 32ks/s, and Osmocom Sink does not resample the data for you (and sometimes does not give you a clear warning when something is wrong). So, I would check whether the stream is really being transmitted at 32ks/s (by using something like Probe Rate).

Hi Verónica, in your long/short_sync_block's __init__, you set the in_sig to [np.complex64], which is of a complex number composed of two 32 bit floats. You can change that to other types! But: your wifi_phy block outputs something specific, it needs to match that. Best regards, Marcus On

Hi Martin, Yes, that could definitely be the case. I don't have my radios right now with me, but I'll try it tomorrow. And sorry for the silly question, but how should I define it in Python to be fixpoint? On Thu, Nov 25, 2021 at 6:25 PM Martin Braun wrote: > Verónica, > > have you maybe misma

Verónica, have you maybe mismatched data types? Like, the real signals are fixpoint, but your Python is doing floating point? --M On Thu, Nov 25, 2021 at 2:59 PM Verónica Toro Betancur wrote: > Hi, > > I am trying to detect and decode WiFi and ZigBee signals in GNURadio. For > the detection, I

I'm doing a similar thing for something that works like zigbee. Do you have a link to your code? I think it should be working better than what you're seeing. -Michelle W5NYV On Thu, Nov 25, 2021 at 5:59 AM Verónica Toro Betancur wrote: > Hi, > > I am trying to detect and decode WiFi and Zig

RF signals are pure noise in Python implementation

Hi, I am trying to detect and decode WiFi and ZigBee signals in GNURadio. For the detection, I have implemented my own blocks in Python. It all works well with simulated signals but the problem comes when I use radios to acquire real signals. I'm using Pluto SDR and it works perfectly when I use i
