I am searching for an answer to the above question for many days. Some related questions have been asked in StackOverflow, for example: this and this. However, they suggest that it's not possible.
I want to use the RSS from Wi-Fi devices (access points) for indoor localization. It's quite easy with Android devices, where certain permission to access the Wi-Fi module is required. However, with iOS (iPhones), I couldn't find a way.
A published journal has reported the indoor localization result using iPhone6 with Wi-Fi signals. But it doesn't say how did they do it. I had sent an email to the author of the paper, however, I couldn't get a reply.
Is there any way to access the Wi-Fi (scan the RSS of Wi-Fi devices) using iPhone? Has anybody done it?
If it's possible, a small hint or a small code snippet would be very helpful.
Thank you.
