i am trying to upload the ubitx v6 firmware to a v6 ubitx. . the sketch compiles ok but i get the following error when i try to upload?

upload error

arvdude: ser-open(): can't set com-state for "\\.\com4"

failed uploading: uploading error:exit status 1

with the mini usb cable connected from the arduino nano to the pc the device manager shows com 4 usb serial CH30, the arduino ide tools>ports>com4? (no ch30).

the device manager says? my driver is up to date

i fixed it thanks to another post here on same issue

no help needed

My issue was the baud rate, newer boards require 115200 which I found through the help of the group too.?
