I have a Dell Latitude E7250 with
Bus 001 Device 003: ID 8087:0a2a Intel Corp. Bluetooth wireless interface
and Bluetooth seems to work fine minus some Linux warnings [1] and a problem transferring greater than some bytes files with the Nokia N9 [2].
Linux 5.16-rc3, Dell Inc. Latitude E7250/0TVD2T, BIOS A19 01/23/2018:
``` $ sudo dmesg | grep -i bluet [ 8.173417] calling bt_init+0x0/0xb3 [bluetooth] @ 301 [ 8.173439] Bluetooth: Core ver 2.22 [ 8.173463] NET: Registered PF_BLUETOOTH protocol family [ 8.173464] Bluetooth: HCI device and connection manager initialized [ 8.173467] Bluetooth: HCI socket layer initialized [ 8.173470] Bluetooth: L2CAP socket layer initialized [ 8.173473] Bluetooth: SCO socket layer initialized [ 8.173475] initcall bt_init+0x0/0xb3 [bluetooth] returned 0 after 35 usecs [ 8.216875] Bluetooth: hci0: Legacy ROM 2.5 revision 1.0 build 3 week 17 2014 [ 8.233515] bluetooth hci0: firmware: direct-loading firmware intel/ibt-hw-37.8.10-fw-1.10.3.11.e.bseq [ 8.233520] Bluetooth: hci0: Intel Bluetooth firmware file: intel/ibt-hw-37.8.10-fw-1.10.3.11.e.bseq [ 8.540884] Bluetooth: hci0: unexpected event for opcode 0xfc2f [ 8.558942] Bluetooth: hci0: Intel BT fw patch 0x32 completed & activated ```
