I've got today new MSI X870E Tomahawk WiFi board and it comes with Qualcomm WCN785x for WiFi/Bluetooth. While Bluetooth is available and can scan for the devices, I cannot complete the pairing process with following errors in logs: Mar 19 00:56:01 bluetoothd[1456]: src/device.c:search_cb() EC:73:79:59:9A:4E: error updating services: Input/output error (5) Mar 19 00:56:17 bluetoothd[1456]: src/device.c:search_cb() EC:73:79:59:9A:4E: error updating services: Input/output error (5) Mar 19 00:56:17 bluedevil-wizard[40108]: kf.bluezqt: PendingCall Error: "br-connection-create-socket" I can see that device is added and set to trusted, but attempt to connect shows the same error: Mar 19 00:57:33 bluetoothd[1456]: src/device.c:search_cb() EC:73:79:59:9A:4E: error updating services: Input/output error (5) Mar 19 00:57:33 systemsettings[40016]: kf.bluezqt: PendingCall Error: "br-connection-create-socket" Please let me know what other information I can provide to help.
So, I seems to workaround the problem by passing bluetooth device into the Windows 11 VM and installing driver (https://download.msi.com/dvr_exe/mb/qualcomm_ncm865_bt.zip) for what is written as Qualcomm NCM865 (WCN785x is probably a WiFi part?) Is it probably a missing firmware (dfu files in the package) and now it's using the one windows loaded?
