I have a RapsberryPi3 running windows iot. I am using the Rfcomm chat example to communicate with it using an android device over bluetooth. I managed to establish the connection successfully but after running the application for sometime(about 20-25 minutes), if I try to connect my android device to the Pi, the two devices are unable to connect. If I reboot the application, it connects again. I tried running the chat example on my desktop and have my phone connect to it and it works fine. Is this a know issue with RasberryPi?
