Failed to connect to peripheral xx:xx:xx:xx:xx:xx, addr type: random/public

Hi,
I wanted to understand why this exception appears? However when i try to force to connect to peripheral and enumerate it several time it sometimes works and show desired output, but most of the time i got the error - Failed to connect to peripheral xx:xx:xx:xx:xx:xx, addr type: random
or
Failed to connect to peripheral xx:xx:xx:xx:xx:xx, addr type: public

Edit: I use Bluetooth adapter.

Same issue here. I use my internal WLAN/Bluetooth adapter.

Update: I bought a Bluetooth adapter. Program works without problems. The issue you have is most likely because some process is using your adapter. Is it the only hci on your computer?

You could try:

sudo service bluetoothd stop
sudo hciconfig hci0 down
sudo hciconfig hci1 down (if you have a second adapter)
sudo hciconfig hci0 up
sudo hciconfig hci1 up
sudo service bluetoothd start

Please give me feedback to this solution!
Note: There is no right solution in the Bluetooth world. What a shitty protocol...
