Dear List, I have an iPazzport bt mini keyboard that won´t connect. Bluez is version 5.58, kernel 5.11.11. Below I put the output from btmon. The battery in the keyboard is charged, checked twice. BT adapter is an onboard Qualcomm/Atheros 0cf3:e500 device in a laptop. Could it be, the adapter needs to be put in HID mode? How can I find out, what mode the adapter uses? I could not see in lsusb -v what mode the adapter uses. Below I put btmon output, the same output as screen shot, more eye friendly there: https://ibb.co/NZC3zKD Thanks a lot in advance ! ~$ btmon Bluetooth monitor ver 5.58 = Note: Linux version 5.11.11-1.tpad (x86_64) 0.070249 = Note: Bluetooth subsystem version 2.22 0.070257 = New Index: 00:F4:8D:C9:40:5E (Primary,USB,hci0) [hci0] 0.070261 = Open Index: 00:F4:8D:C9:40:5E [hci0] 0.070269 = Index Info: 00:F4:8D:C9:40:5E (Qualcomm) [hci0] 0.070273 @ MGMT Open: bluetoothd (privileged) version 1.19 {0x0001} 0.070278 = bluetoothd: profiles/input/device.c:ioctl_is_connected() Can't get HIDP connection info 46.562408 < HCI Command: Create Connection (0x01|0x0005) plen 13 #1 [hci0] 46.562467 Address: 54:46:6B:01:99:DA (Shenzhen CZTIC Electronic Technology Co., Ltd) Packet type: 0xcc18 DM1 may be used DH1 may be used DM3 may be used DH3 may be used DM5 may be used DH5 may be used Page scan repetition mode: R2 (0x02) Page scan mode: Mandatory (0x00) Clock offset: 0x0000 Role switch: Allow slave (0x01) > HCI Event: Command Status (0x0f) plen 4 #2 [hci0] 46.565296 Create Connection (0x01|0x0005) ncmd 1 Status: Success (0x00) > HCI Event: Connect Complete (0x03) plen 11 #3 [hci0] 51.687430 Status: Page Timeout (0x04) Handle: 2 Address: 54:46:6B:01:99:DA (Shenzhen CZTIC Electronic Technology Co., Ltd) Link type: ACL (0x01) Encryption: Disabled (0x00) @ MGMT Event: Connect Failed (0x000d) plen 8 {0x0001} [hci0] 51.687500 BR/EDR Address: 54:46:6B:01:99:DA (Shenzhen CZTIC Electronic Technology Co., Ltd) Status: Connect Failed (0x04) = bluetoothd: profiles/input/device.c:control_connect_cb() connect to 54:46:6B:01:99:DA: Host is down (112) 51.688047
