hi when i record an IQ file using rtl sdr and send it back it says Warning samplerate too high decimation by 2 will be performed and i dont get anything on the device am trying to make the replay attack on i truly wish you'll help me ! the frequency is 433mhz and the second one is 315 mhz knowing that i have tried everything i found on the issues guide and am using a raspberry pi 3 model B+

same thing here, using raspberry 3b+ (Buster)and I get the same message, the transmitted signal is longer (in ms) than original one. Any idea why this happens?

Here is a solution that worked for me:

1. Delete the installed version.
2. Clone the repo again.
3. Before running install.sh, open src/sendiq.cpp file.
4. Search for #define MAX_SAMPLERATE 200000
5. Change it to 250000
6. Run install.sh as usual.

It worked for me on Kali-2019.1-rpi3-nexmon

is this still working on kali 2020? i kept getting the same error after I change the Sample rate in sendiq.cpp file

you might want to check the path to the IQ file because it looks like this "samplerate too high decimation by 2 will be performed" when the file is nowhere to be found. Usually saved in another directory.
