I am regularly having trouble that an application is unable to connect to a nearby bluetooth device without an obvious reason. The connection is made each 5 minutes. The distance is only 10 to 20 cm. In order to make things work, I have a monitoring script that each 15 minutes does a "timeout -k 10s 1m hcitool scan". When it times out after 1 minute, which occurs a few times per day, the script reloads the driver and things are OK again. The system is a Raspberry Pi 1B, with linux kernel 4.1.6, bluez-5.33-1.1, libbluetooth3-5.33-1.1, and bluez-firmware-1.2-148.1. The bluetooth device is: Bus 001 Device 004: ID 0cf3:3005 Atheros Communications, Inc. AR3011 Bluetooth Should I use bluetoothctl? If so, where do I find comprehensive documentation on it? -- fr.gr.
