I am trying to utilize the facility in Chrome to be able to use passkeys stored on an Android phone with the demo site at passkeys.io. I have tried this on 3 computers I have access to and it only seems to work on one of them and the Bluetooth operation fails on two of them. The one that works is running Fedora 38 with bluez-5.70-5.fc38.x86_64 on a: Bus 001 Device 005: ID 8087:0026 Intel Corp. AX201 Bluetooth BT adapter. One that is not working is running Fedora 39 with bluez-5.71- 1.fc39.x86_64 on a: Bus 003 Device 004: ID 0a5c:2121 Broadcom Corp. BCM2210 Bluetooth BT adapter. The other one that is not working is also Fedora 39 with bluez-5.71- 1.fc39.x86_64 but I cannot seem to see a BT adapter in the output of either lspci or lsusb. But I can see that it has a BT adapter: $ bluetoothctl Waiting to connect to bluetoothd...[bluetooth]# hci0 new_settings: powered bondable ssp br/edr [bluetooth]# Agent registered [bluetooth]# [CHG] Controller 70:F3:95:3E:92:34 Pairable: yes Any clues or hints on how to further debug why these two non-working systems are non-working given that this does work on the third system? Cheers, b.
