I have an custom Bluetooth LE application running on the Raspberry Pi 3, that does a lot of connecting/disconnecting of bluetooth connections and seem to be having connectivity problems. I get a lot of "Function not implemented (38)" and " Device or resource busy (16)" errors. The application runs error great on other platforms, or if I use a usb bluetooth adapter on the RPi 3. The problem also seems to be a lot worse when I have bluetooth operating concurrently with wifi.
I was wondering if anyone else was having similar problems or has any suggestions on what could be causing the problem.
Thanks in advance.
