PuTTY unable to open serial port over Bluetooth connection to Raspberry pi 4b Mon 6:48 am I am trying to access my terminal through a Bluetooth connection on my windows 10 laptop to my raspberry pi 4b. I have tried connecting to the port with both computers from PuTTY and both computers give the same error: The device shows up on both in the Device Manager under 'Ports (COM & LPT)' and driver says it is Cypress v.2.0.0.2 I have installed PSoC Creator on two different computers both running Windows 10.

I wonder if this is some hangover from the old driver getting picked up when you put in a new device. I using the PSoc 6 Pioneer kit to go through the PSoC 101 video series. When I did, Windows reported that there was a problem and could not start the serial port driver.
