Bluetooth with iOS

K. First time with bluetooth here… trying to understand how it works. My serial monitor keeps saying connection failed. Does that mean I need to connect my uno to the internet before bluetooth will connect to my phone? Maybe its just to late over here!

Never used BT, but I thought you used the BT widget to connect to the device (HC-05 ?).
If the device isn’t visible then check the connections and baud rate settings.
