Invalid Preamble when reading the BIN file through GNSS SDR (MATLAB) #325

Hi, first of all, I am extremely sorry for asking so many questions again and again

Actually, I have generated the BIN (signal) file and when I transmit it through USRP I can see PRNs on the phone which means the acquisition is successful but there is no tracking and no navigation solution...

I tried testing the signal with MATLAB-based SDR (developed by Kai Borre) but it says invalid preambles. I am so confused what could be the problem behind this issue?

Please see the following images for further clarification.

Thank you image

This should be fixed in the latest code.
