Visual Micro does not operate DTR on NodeMCU

While Arduino IDE flashes the device without any human intervention, in case of Visual Micro it is necessary to keep Flash button pressed at the beginning. Obviously there are some adjustments to solve this. Does anybody know?
Thanks in advance.

Hi,

Thanks for the report. 

I can see there are some relatively new settings in the esp config to instruct dtr/rts to be disabled to cause a reset.

Which version of the arduino ide are you using? Where downloaded from?

Thanks

Thanks. Your solution that you mention is unrelated to visual micro. These are internal settings for the toolchain which means that Arduino and vm should do the same things.

Where did you download 1.6.4?

Strange question. https://www.arduino.cc/en/Main/Software

Ok.

If you search the issue on the web esp8266 made a hybrid arduino.exe to get around the issue (and others)

Since Arduino 1.6.2 they have standardized and now use the main arduino ide however not everyone knows that and it can cause confusion when people say they are using the arduno ide.

We need to log a question on the esp site because the change you made is not something that affects visual micro. One question is why did it work in the arduino ide with the standard config but not in visual micro and what is the difference between the two options you used?

I have two Visual Micro installation: at home and at office.
The office one works fine, at home PC required to push the Flash button. Did not inspect boards.txt at home PC yet.

Can you confirm that on the home pc the arduino ide works?

Yesterday I published a new version of visual micro which responds differently to a few flags in the espconfig serial.disableDTR=true and serial.disableRTS=true.  These settings might be redundant since the newest esptools manage the reset and not visual micro.

The changes might have no effect what so ever, might fix it or might break it. I would appreciate your trying it out so that I can revert the changes of they don't work

If you try it and find the upload is worse than before then you can revert to the last release here https://visualstudiogallery.msdn.microsoft.com/069a905d-387d-4415-bc37-665a5ac9c...

I would also be interested to know the version of esp firmware you have installed at home and at work (see boards manager)

Thanks

Well,
reset method in boards.txt affects only on Arduino IDE programming behavior. 
At home PC I have two versions of ESP packages installed:
1.6.5-1160-gef26c5f and
1.6.5-947-g39819f0
the first one is the active. They have different reset methods: 
1.6.5-1160 
nodemcu.upload.resetmethod=nodemcu
nodemcuv2.upload.resetmethod=nodemcu
1.6.5-947
nodemcuv.upload.resetmethod=ck
nodemcuv2.upload.resetmethod=ck

Changing to ck makes Arduino IDE programming impossible
with no affect to Visual Micro. 

I also have ESP8266 generic 8-pin modules. I connect them to FTDI chip as following:
DTR - GPIO0
RTS - RESET
in the boards.txt al settings for ESP generic are set to ck.
These modules are flashed perfect in Adruino and Visual Micro.

That is all for the moment.

I reverted the visual micro build yesterday but the changes can be enabled for testing from boards.txt

Before we do this it would help to have clarification from the esp site about how their reset methods are supposed to work. I cant see how with method one and two visual micro has any control
