So im basing my project on your Android-nRF-UART-master example found in github, i don't know if its a app bug or issue regarding the circuit, but first connection is always done correctly, fully functional, but once i disconnect and re connect to the same device as soon as I write on the TX channel it will pop the tittle message, really weird, happens on both my app and your example code. the app needs to be re launched.Any idea of what might be happening?
