ModemManager RaspberryPi Bluetooth Issues
We experience problems using a D-Link USB Modem with ModemManager on a Raspberry Pi 3.
As soon as we start our application which uses the hci0 Bluetooth interface, ModemManager receives the signal to stop from the system and vice versa.
Do you have any idea why this could be the case? We have already run through the manual and documentation to investigate the device detection/discovery mechanisms and tried to disable it for the /dev/ttyAMA0 device, bluetooth subsystem, different block, or allow approach with udev without udev.
