Hi all! I introduce myself, my name is Osvaldo, I was recently learning to use Xamarin C # (I only knew how to use Java), I'm doing a hybrid application where from an iPhone or an Android phone can connect via bluetooth to a Raspberry pi zero w, the application has worked but only to a certain extent, first I commented that the application reads LE devices, but not the Raspberry, second the application is only working so far on Android and I do not know why it does not work on IOS, and third I have to extract from the Raspberry the SSID and the wifi password to which it is connected, if you can guide me and help me solve this, I would appreciate a lot !!!
PD: sorry for my English, but I'm still practicing.
