Unable to connect to Micro:Bit using mbed serial to Putty

I'm using Windows 10 and Device Manager shows: mbed Serial Port (COM7) Port settings show: 115200, 8 None 1, flow control None

Putty uses serial COM7 115200. When I connect (started putty as admin) nothing displays, even after clicking enter numerous times.

I tried deleting and reinstalling mbed port / mbedWinSerial_16466.exe and also tried teraterm instead of putty. I know the microbit is com7 because when I physically remove it com7 disappears from Device Manager. I tried several different usb ports as well.

Any idea how I can connect to microbit serially?

THis is very strange indeed,

What is the example program you are using, is it specified at 115200 baud? mbed defaults to baud 9600, posting you code may help.

Have you also tried another cable?

Best Regards,

Andrea, team mbed

I am following this page to get this working: https://www.microbit.co.uk/td/serial-library "Using the serial library in your programs If the serial button is not available, you will need first to add the micro:bit serial library to your script: tap on add new tap on library select micro:bit serial"

What do they mean by "tap on add new"?
