Topic: Can not upload to MKR FOX 1200 - COm port busy (Read 1 time) previous topic - next topic


Dear All,

I have uploaded a sketch to the MKR FOX 1200 and it works well, but I have made some changes to the code and now each time to try I get the following error:

   at cc.arduino.packages.uploaders.SerialUploader.uploadUsingPreferences(SerialUploader.java:152)

I have rebotted the PC several times, restarted Arduino app and reset the board.  I have dsicnnected all the pins from the device but nothing makes any difference.

Having read the guides on here, I have also disabled the bluetotth adaptor I have and and vitrual com ports.

Any help will be appreciated as I am stuck at the moment.
