Administrators Hervé Posted March 20, 2018 Administrators Share Posted March 20, 2018 Again... [...] Check your SysProfiler for an eventual Bluetooth device under USB. If the card is combo indeed, the Bluetooh module should be listed there, whether it works or not. Posting your PCI list is of no use for USB-based Bluetooth! You'll have to tell us what you see under SysProfiler->USB to identify the eventual BT chip in place and give us its displayed PCI ids. Is it a DW1701 card?

Administrators Hervé Posted March 21, 2018 Administrators Share Posted March 21, 2018 There's no Bluetooth device listed so it's probably disabled in BIOS or the card is in a WLAN slot, not a WWAN one. Combo cards must be installed in combo mini-PCIe/USB slots such as WWAN for the BT module to operate. Once you've done the needful, you'll see that the listed BT module is of Broadcom BCM2070 (BT3.0 I think) nature which is normally supported under OS X/macOS. You may require Rehabman's firmware-related add-on kexts to get BT working properly, albeit with some limitations in terms of application support (since it's not BT4.0 or higher). https://github.com/RehabMan/OS-X-BrcmPatchRAM All in all, you'd have much to gain by simply replacing this card by a fully supported and more modern card (DW1701 is 9yrs old, as is BT3.0+HS technology).
