I want to be able to transmit live data from a sensor attached to the arduino to my iphone. Would i need a ble chip for that? I want the data to go to a custom ios app, not one on the app store already
Google for "Transmitting live data from sensor to iphone". There are lots of tutorials using a variety of BLE devices.
Are all Ble devices the same, or is there a preferred one?
Here's an example, uses HM-10 BLE and MIT App Inventor for the phone part:
I don’t think MIT app Inventor is ready for IOS - yet.I imagine there is another way to get a custom app on IOS.
