The installation script calls a tool that expects python to be of version 2. Please consult the search engine of your choice to figure out how to get the environment...

The tool we are talking about uses a shebang [here](https://github.com/seemoo-lab/nexmon/blob/29d990bdaea869cb32f5eaa2dbb7efacdcd405aa/buildtools/b43-v3/debug/b43-beautifier#L1). So if you manage to install python2 on your system you can also edit this to use version 2 directly.

I guess you are referring to `frame.header.ts_sec` and `frame.header.ts_usec` read from a pcap in `utils/matlab/readpcap.m`? That timestamp is generated by `tcpdump` when capturing frames and does not represent the time...

A bit more patience required.

Hi @TQMatvey, no, I don't provide already patched firmware. You have to build it yourself. But you can try using the one for the Pixel 7 Pro, might work as...

Try with NDK r11c ([download here](https://github.com/android/ndk/wiki/Unsupported-Downloads#r11c)) as stated [here](https://github.com/seemoo-lab/nexmon#how-to-build-the-utilities).
