Hi @Shade21, Thanks for your feedback ! I'm afraid this is an old project I did for school on a older version of android, and I don't have much time to spend on it... My apologies ! I think the problem comes from the NFCAdapter library I use, maybe you can try to use it another way. I wish you good luck debugging it ! And let me know if you fix the issue ;)

Thanks for your answer. I want to ask another question. I have a beacon and Is your project can detect it's uuid, major, minor, RSSI ? or distance?

ThibaudCrespin commented 7 years ago

UUID, major, minor and RSSI yes I guess, it's provided by the NFCAdapter library. But distance you'll need to create a function, I wanted to do it but totally forgot !
