I am using the Nvidia nano board. But it can not scan the nano 33. I can see some other devices in my office though.
I can see the nano 33 on my android though. (I have disconnected the nano 33 from my phone before scanning from my Nvidia nano board)
The Intel chip product brief says this is a dual mode Bluetooth device. Dual mode means Bluetooth Classic and BLE. The two protocols are not compatible. Are you sure you are using BLE and not Bluetooth Classic?
Another potential issue is Linux. From what I have seen on Raspberry Pi there are access right issues stopping some BLE applications from working. But, I have not investigated this enough to tell you more.
