need major help, here is what I have tried so far:
my goal:
App1Terminal: Waits for a mobile device to get in proximity
App2Device: Comes in proximity, opens channel with App1Terminal and sends some data
App1Terminal: Receives data from App2Device and responds with some level of decision as well as shows decision on its screen
App2Device:Gets the result of action from App1Terminal and shows it on the screen
Since it is NFC(I think it is nfc that is suited for this) App1Terminal will ONLY entertain a NFC connection from App2Device apps, and same for App2Device it will only send message to App1Terminal.
I create both applications, using nfc I am able to read a NFC tag, however I am not able to make a communication between 2 devices.
My test devices were samsung J7(app1terminal) and S9(app2device)
I have tried even HCE communication…but failed miserably…All the data that I search on these topics is older..eg few years old, and much of the code seems to have been deprecated.
Can some one please help, What I do not understand is that google wallet works exactly the same way on POS devices, they both communicate and send data between each other.
Please guide ..Thanks
