Arduino disconnect and reconnect causes exception when uploading if serial monitor left open

Open pfeerick opened this issue 10 years ago • 24 comments

Related partly to #3379 (actually discovered due to testing repeatability).

An exception error will occur if the serial monitor is opened, the arduino is unplugged, plugged back in, and then uploaded to. When you click upload a second time, it disables the serial monitor properly and uploads.

A fix to #3379 has just been pushed. Can you retry with the latest hourly build? http://www.arduino.cc/en/Main/Software#hourly

Just tested the Arduino 1.6.6 2015/06/23 05:51 hourly build, the exception message is gone, but now all that happens is the status area says 'Uploading to I/O Board...' - it doesn't compile and upload. If I click on upload a second time it does work.

Does avrdude say the com port in unavailable?

ffissore avatar Jul 02 '15 08:07 ffissore

I've just tried again with the latest hourly build, please ignore my previous message about it the message going away... with Hourly 1.6.6 2015/07/03 10:41 it is still there... I mustn't have waited long enought or held my tongue right before :-o error log reproduced below just in case it has moved....[which it has - AbstractMonitor and Editor are showing different line numbers]

Running the debug version of the IDE didn't give any more information. It looks like the gremlin is still in the IDE - which clears when clicking the compile button a second time.

The problem still occurs in 1.6.9 on Windows 10. It seems to alternate between Can't Set Mask and Port Not Found.

bcraigie avatar Nov 26 '16 20:11 bcraigie

Does it occur in 1.6.13?

oqibidipo avatar Nov 28 '16 00:11 oqibidipo

I am experiencing the same error on an Arduino Leonardo Clone w/built in CC3000 Wifi (DFRobot WiDo) Board. I'm trying to determine if it is related to the issue I'm experiencing where the board will run for a few seconds after it I flash it, then halts in its tracks with a red light steady and pin 13 stuck in on position. It will report an attempt to initialize the Blynk library and communicate via Wifi, but stops before it can ever actually establish a network connection.

Same for me, after an update of windows 10. IDE 1.8.5, on Arduino Due.

axellettieri avatar Jan 07 '18 03:01 axellettieri

is there any fix for this issue? (IDE 1.8.5 on ESP8266)

rugo100 avatar Feb 23 '18 17:02 rugo100

Exactly same proplem! (IDE 1.8.5 on ESP-WROOM-32)

PCees4u avatar Mar 16 '18 14:03 PCees4u

Same here. (IDE 1.8.7 on Adruino Uno w/ ESP8266-01 connected)

Thanks pfeerick , I had a similar issue and your comment helped

simitenbiri avatar Jan 08 '19 10:01 simitenbiri

same issue here arduino 1.8.8 on esp8266-01

SergiuToporjinschi avatar Feb 06 '19 21:02 SergiuToporjinschi

same issue in Arduino 1.8.8 on esp32

Lopes2700 avatar Mar 14 '19 14:03 Lopes2700

Same issue with Tongze ESP8266/FTD232R Bridge and Ardurino IDE 1.8.9 Sensitive to Serial Monitor being on when uploading?

Buzzardbait avatar Jul 11 '19 23:07 Buzzardbait

Oh, that was silly (and embarrassing)! The FTD FT232R looked like it could power the Tongze shield when not mounted on the UNO/MEGA but it eventually overheated and symptoms were as described above. Ended up powering shield by mounting on the MEGA board and being careful to only connect Tx, Rx and Gnd (not 3.3v) from FT232R to the serial debug port. Shield works fine now (but probably not via MEGA D0 and D1 pins). Need to work on that.

@deviprasannaraju did you solve ?

Jeevesh8 avatar Sep 20 '20 15:09 Jeevesh8

That was a long time ago and I haven't had any problems with the MEGA or UNO boards in a long time.

Buzzardbait avatar Sep 20 '20 17:09 Buzzardbait

The problem is still relevant

Makcal avatar Sep 28 '21 21:09 Makcal

The problem is still there and relevant. Is there a fix for it? Thank you.

TomMandle avatar Jan 04 '22 03:01 TomMandle

Hi, did someone find the solution to this problem?

Still relevant (1.8.16) and looking desperately for a solution.

ireluq avatar Mar 24 '22 10:03 ireluq

same here. using arduino IDE 1.8.19 and arduino pro micro.

bwanaaa avatar Apr 18 '22 20:04 bwanaaa

Hi all. Please try with the latest version of Arduino IDE 2.x and comment here to let us know whether the problem still occurs.

The Arduino IDE 2.x download links are listed here:
