I downloaded and compiled bluez-5.34.tar.xz. uname -a says: Linux raspberry 4.1.6-v7+ #810 SMP PREEMPT Tue Aug 18 15:32:12 BST 2015 armv7l GNU/Linux My BLE-stick is recognized and hci0 is up and running. I can scan for advertising peripherals with "sudo hcitool lescan". This works. But if I try to connect to a peripheral I always get Connection refused (111). So I looked at the output of hcidump and found that after the connection is completed, I get disconnected by remote. < HCI Command: LE Create Connection (0x08|0x000d) plen 25 bdaddr 34:B1:F7:D4:FE:F3 type 0 interval 4 window 4 initiator_filter 0 own_bdaddr_type 0 min_interval 15 max_interval 15 latency 0 supervision_to 3200 min_ce 1 max_ce 1 > HCI Event: Command Status (0x0f) plen 4 LE Create Connection (0x08|0x000d) status 0x00 ncmd 1 > HCI Event: LE Meta Event (0x3e) plen 19 LE Connection Complete status 0x00 handle 72, role master bdaddr 34:B1:F7:D4:FE:F3 (Public) < HCI Command: LE Read Remote Used Features (0x08|0x0016) plen 2 0000: 48 00 H. > HCI Event: Command Status (0x0f) plen 4 LE Read Remote Used Features (0x08|0x0016) status 0x00 ncmd 1 > HCI Event: LE Meta Event (0x3e) plen 12 LE Read Remote Used Features Complete status 0x00 handle 72 Features: 0x01 0x00 0x00 0x00 0x00 0x00 0x00 0x00 < HCI Command: Disconnect (0x01|0x0006) plen 3 handle 72 reason 0x13 Reason: Remote User Terminated Connection > HCI Event: Command Status (0x0f) plen 4 Disconnect (0x01|0x0006) status 0x00 ncmd 1 > HCI Event: Disconn Complete (0x05) plen 4 status 0x00 handle 72 reason 0x16 Reason: Connection Terminated by Local Host I tried three different peripherals and I always get "Connection refused (111)". Any ideas would be appreciated. Best regards, Mike
