I'm analyzing a signal RF OOK with a RTL-SDR device. I'm a newbie with GnuRadio so I use it only for make a wave audio of the signal and analyze it. This is my flow graph taken from here
How I can extract the time in ms/us when there is modulation and when there is silence? I tried with audacity but is not easy to calculate.
I tried to use the project rtl_433 with command line
-a -s 1000000for analyzing but it with give me only:
*** signal_start = 8925959, signal_end = 9279917Is there a way for convert pulse length in time? I see if I change the sample rate change also the length.
signal_len = 353958, pulses = 191
Iteration 1. t: 483 min: 323 (87) max: 643 (104) delta 99289
Iteration 2. t: 486 min: 323 (89) max: 650 (102) delta 49
Iteration 3. t: 486 min: 323 (89) max: 650 (102) delta 0
Pulse coding: Short pulse length 323 - Long pulse length 650
Short distance: 320, long distance: 643, packet distance: 11349
I tried the project ook_decoder but doesn't work it see only rumors.
Sorry for my very newbie question and thank you for your suggestions.
