I am new to raspberry pi and still in the learning phase. I have a small project which requires the communication between pi and android app. I need to accomplish the following task - establish a connection between the app and the pi over the wifi. After that, I need to employ some object detection on the pi to identify what objects the user has picked and later display the items on the user's app. I have seen some tutorials on object detection on pi using on tensor flow and I believe I can do it. Where I am stuck is how do it send the data from the pi to the user's app. I have searched for links on the same but still am unable to figure out how to do it. Do I need to make the pi as a web server to accomplish this? Please don't mind if the question is silly. Any links to similar tutorials like these or any steps I should follow to achieve the task would be very much appreciated. Thanks in advance.
