I’ve had some serious problems upgrading from Arduino 1.8.6 to 1.8.9. After 3 re-installs I finally am able to Upload Sketches, but now I cannot get Serial Monitor to come up. I’ve been on the Arduino forum twice, but I get no response. I’ve checked all the settings – they seem to be OK. Any idea how to fix this problem?

Hi
https://github.com/arduino/Arduino/issues/3781
Arduino IDE exists at different parts of C: drive
Basic uninstall does not remove all of it
try
after uninstall
delete these folder or rename them
C:\Program Files (x86)\Arduino
C:\Users\******\Documents\Arduino // your Sketches are stored … best rename it
C:\Users\******\AppData\Local\Arduino15 // this is found in Preferences tab (at the bottom) strores Libs Preferences.txt
Reboot PC maybe required
then reinstall IDE
Might solve your problem

Hi,
DK…Well I followed all your suggestions except the one:
C:\Users\******\AppData\Local\Arduino15 // this is found in Preferences tab (at the bottom) strores Libs Preferences.txt – I did not understand where the preferences tab is. So I did a search on Arduino15 for the entire Users folder and got nothing!
I tried running the blink sketch with two lines added to activate the Serial Monitor – “HIGH” & “LOW”, where as the blink worked without the serial monitor output before, now the sketch would not upload, so I’ve taken a step backwards. Here is the error message:
Sketch uses 2000 bytes (6%) of program storage space. Maximum is 32256 bytes.
Global variables use 196 bytes (9%) of dynamic memory, leaving 1852 bytes for local variables. Maximum is 2048 bytes.

Any further help you can provide would be greatly appreciated.

Hi
C:\Users\******\AppData\Local\Arduino15 //
Preferences tab is File – Preferences in Toolbar

You need to install all packages again
Common mistakes I make when switching between pic is choosing the correct board (from Board Manager)that I using and its Port

Hi DK,
I’m making progress, but this last installation of 1.8.9 is a real stripped down version of basics only. Board-> shows only Arduino boards & I have a NodeMCU 1.0 (ESP-12E Module). Boards Manager normally shows hundreds of options, now it only shows 6. It’s been over a year since I installed my ESP 8266 and I forgot how I installed it, and most of the stuff on the internet is crap!
Once again, can you help me. 1.8.6 worked perfectly. Ever since 1.8.9 it’s been a nightmare.

Hi
there two ways of installing packages on Arduino IDE
esp8266 and esp32 all version

Hi DK,
Followed the ESP8266 install to the letter. Small progress – I now have a Serial monitor back. However the same old error messages are back:
Sketch uses 942 bytes (2%) of program storage space. Maximum is 32256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0xf5
avrdude: stk500_recv(): programmer is not responding
Will this nightmare ever end?

hi
try
choosing the esp8266 from Board Manager and use the Port assigned to it

Everything works!! All my sketches, finally. I had to remove the wire from pin 0 (GPIO16). Thank you so much for your patience.
P.S. The Arduino forum has been a real disappointment to me. Most of time my posts get ignored. When I do get a response, it’s usually total nonsense. The ESP8266 forum is not much better. This is the forum I have been able to rely on. Really good people like yourself. Once again, Thanks.
