This uses Bluetooth Low Energy. Under dual boot Windows 8.1 I can connect this mouse, and it will reconnect just fine if I turn the mouse off/on or Bluetooth off/on. In Fedora rawhide I have Bluez 5.18-2. I can pair this mouse just fine, and it will continue to work until I turn the mouse off/on or turn the computer off/on. Then it won't reconnect automatically. If I go into bluetoothctl I can connect it again and it will then work. I looked at bluetoothd and it seems to be doing the LE scan with: bluetoothd[2356]: src/adapter.c:trigger_passive_scanning() bluetoothd[2356]: src/adapter.c:passive_scanning_complete() status 0x00 bluetoothd[2356]: src/adapter.c:discovering_callback() hci0 type 6 discovering 1 I look also at hcidump and I see: < HCI Command: LE Set Random Address (0x08|0x0005) plen 6 bdaddr 39:6D:E2:EC:17:37 > HCI Event: Command Complete (0x0e) plen 4 LE Set Random Address (0x08|0x0005) ncmd 1 status 0x00 < HCI Command: LE Set Scan Parameters (0x08|0x000b) plen 7 type 0x01 (active) interval 11.250ms window 11.250ms own address: 0x01 (Random) policy: All > HCI Event: Command Complete (0x0e) plen 4 LE Set Scan Parameters (0x08|0x000b) ncmd 1 status 0x00 < HCI Command: LE Set Scan Enable (0x08|0x000c) plen 2 value 0x01 (scanning enabled) filter duplicates 0x01 (enabled) > HCI Event: Command Complete (0x0e) plen 4 LE Set Scan Enable (0x08|0x000c) ncmd 2 status 0x00 < HCI Command: LE Set Scan Enable (0x08|0x000c) plen 2 value 0x00 (scanning disabled) filter duplicates 0x00 (disabled) It doesn't seem to be finding anything? Is there something else I should try? Thanks, Ryan
