Teensy 3.2 Serial Monitor Problem

Visual Micro with Visual Studio 2015 looks like a great development platform for helping take my Teensy project to the next level of complexity, but I'm having an issue with the Serial Monitor.

When I connect the board to the COM port and upload the sketch, everything is fine...input and debugging output work great.  When I disconnect the Serial COM port from the board, by unplugging it, clicking the CONNECT button or "stopping" the Serial monitor, the sketch freezes and won't restart, even after power down and resetting the board.

Is there any advice on how to gracefully disconnect the board and have it run the sketch properly?  I really don't want to have to comment and uncomment my Serial.println() code, and re-upload  every time I wan to run the sketch standalone.  It seems that is what is being suggested at the bottom of this page:

Thanks for any help.  If I can solve this problem, then I'm sold and will buy the pro license.

Hi,

I am not sure this is anything to do with Visual Micro. Let;s try a few tests

Switch the tool bar from Debug to Release then upload and confirm if problem still exists.

Your own serial should be the only factor to consider in this test.

Thanks

Great thanks for the update.

What was happening was that one or more of the breakpoints (red spots next to code) where set to "stop and wait for the Continue/F5 command". 

So it is always best to make a "Release" upload when you finish debugging, as you have done. 

fyi:

  • Check the "Continue Execution" checkbox on each break-point if you ever want "Trace Only" debugging. 
  • The "vMicro>Debugger>Trace only" command is another alternative which forces all breaks points to continue.
