Bose QC35 II keeps forgetting USB Bluetooth device on Windows!
I have a QC35 II with the latest firmware (4.5.2) and a computer with a Onvian Bluetooth 4.0 adapter. I notice that every time I turn on the headset, I will need to go through the pairing process again on my Windows desktop to connect to the computer. In Settings on Windows, it has QC35 II as one of the paired devices. The windows device name will show up in the Bose Connect app right after pairing. But it does not show up after I power cycle the headset. It seems that the headset cannot remember the Windows device.
As I check further, the headset can correctly remember my iPhone and my MacBook, but has difficulties remembering the Windows device. I tried to clear the Bluetooth device list in the headset and re-setup the device list. The problem is still there.
So far I have had three QC35 devices. For my QC35 I had before, I recall that it could remember all the Bluetooth devices include Windows desktop. And with my first QC35 II, reconnecting to Windows devices are not reliable. About 90% of the time the reconnecting won't work. I asked for a repair and Bose sent me another QC35 II with a later manufacture date (06/19). However, with this newer headset, reconnecting to Windows device never works.
This sound like a firmware issue to me. Can Bose fix this issue in the coming firmware update?
