Can't upload second sketch - could be com5 to com3 enumeration change

Official Hardware Retired 101

I got a tutorial to work but I can't upload a new sketch now. I have checked that the old sketch is still working and the USB serial port should be available to the Arduino IDE.

Perhaps a Win10 software update which apparently changed the COM enumeration from COM5 to COM3 is the culprit. Is there something in a file that I need to check/change? I'll update after trying some more things.

This is the tutorial I got to work first:

I'll try more things and look for script/text files to modify after rebooting my desktop.

This looks like it's in the main troubleshooting post. I'll find another USB port and see if it enumerates differently, etc.

I didn't see it there before I posted.

I moved the cable to a different USB port and it still enumerated as COM3.

I found the COM3 and COM4 ports apparently reverted to windows drivers after a Win10 update. I went to the board manager and updated the Intel Curie Boards by Intel v1.0.4 on top of itself.

I can upload sketches now.

If you go to Windows Device Manager and see USB Serial Port (COM3) it won't work (but a lot of serial communications still will). It now says "Arduino 101 Serial Monitor (COM3)" in Windows Device Manager.

I had it working and then saw core 1.0.5 was available. After installing it, I don't seem to have an arduino101load:

This command:

C:\Users\fred\AppData\Local\Arduino15\packages\Intel\tools\arduino101load\1.6.4+1.18/arduino101load

From this command line:

I got core 1.0.5 to install, and successfully ran the heart rate BLE sketch.
