Hi, your issue is quite similar to https://github.com/StevenMHernandez/ESP32-CSI-Tool/issues/111 . Assuming you use the toolkit without any modification, I can't really help since I couldn't reproduce it on my side. I suggest you go the link and state your similar problem there.

yes we are in the same group. if ever, I think the problem is how the collected data is saved in my laptop, will there be a problem in collecting data if I directly collect it in esp32? I kinda have no idea, if ever the problem is in my laptop then we can just manually delimited and put it into machine learning or???

There won't be a problem with directly collecting CSI data in the esp32, you only need to make sure it has enough storage space and a way to get the data later. Delimiting the data manually is fine too, just make sure the CSI data column isn't changed by the process.

An update:

• we have collected CSI DATA successfully. There are no problems with the coding at all. We used the wrong powershell that is why the findstr is not working. When we decided to switch and command the findstr in CMD, the collected CSI DATA was saved in correct CSV which is it is not in one column anymore, the data's are now delimited. We tried some CSI DATAs and tried filtering and it was also successful too; we are now moving in machine learning; we will update you more if we encounter an issue again. For now, we can close this issue.

The only problem is that the findstr doesn't work in Esp-IDF Powershell so we switch to CMD.
