So now I compiled a 4.101 version of bluez. And I'm a bit surprised, but I Cannot see the bluetoothctl binary... Which means 1. I misconfigured sg or 2. the bluetoothctl is a futuristic dream which comes with a newer version... I think the second is the truth. But no problem if I Can connect to my device. The "hcitool scan" Can see my device, but when I try to connect it looks like worked, but nothing: root@NSA320S:~# hcitool scan Scanning ... 00:11:22:33:44:55 My_Test_device root@NSA320S:~# hcitool cc 00:11:22:33:44:55 root@NSA320S:~# hcitool con Connections: And the 'lescan' also not works: root@NSA320S:~# hcitool lescan Set scan parameters failed: Input/output error The dmesg is clear...
