ESP8266 OTA Upload
Mar 27th, 2016 at 10:48pm
Print Post  
Version 1.1603.20

In earlier versions there was an option in the menu to select if I want to upload using serial or OTA
This is now missing and when I select an OTA port in the "Serial port" selection it tries to upload using serial.

Code
Select All
Uploading to I/O board using '192.168.31.211'
The uploader returned an error
error: Failed to open 192.168.31.211
error: espcomm_open failed
error: espcomm_upload_mem failed


Is this an error or how does it work now?

Thanks in advance

Hi,

I am not sure how old your previous version was but the esp option should be on the "Visual Micro" menu.

Can you select "Option 6: Upload using OTA" on the "Visual Micro" menu?

Latest trunk from today.
Ohh, perhaps it was not the VisulMicro-update but the update of the arduino core I did today?

More likely, the esp is a moving target Smiley it's good but always changing.

I am using this board support url and the board manager show I have "2.1.0-rc2" installed
http://arduino.esp8266.com/staging/package_esp8266com_index.json

It's important to be clear about your version because the location of esp cores also changes. The last info  had was that staging was most current  Smiley

I gues I found what they did.
The removed this from boards.txt:
nodemcuv2.menu.UploadTool.esptool=Serial
nodemcuv2.menu.UploadTool.esptool.upload.tool=esptool
nodemcuv2.menu.UploadTool.esptool.upload.verbose=-vv
nodemcuv2.menu.UploadTool.espota=OTA
nodemcuv2.menu.UploadTool.espota.upload.tool=espota

At the top of the file
menu.UploadTool=Upload Using

and in the nocemcuv2 part
nodemcuv2.menu.UploadTool.esptool=Serial
nodemcuv2.menu.UploadTool.esptool.upload.tool=esptool
nodemcuv2.menu.UploadTool.esptool.upload.verbose=-vv
nodemcuv2.menu.UploadTool.espota=OTA
nodemcuv2.menu.UploadTool.espota.upload.tool=espota 

and I have the menu item back and OTA update is working

Thanks for the update.

I think there is some confusion somewhere. Maybe you have "visual micro>always use programmer for upload" checked. In early esp8266 versions they made use of the arduino programmer system which was fine for VS but cumbersome in the arduino ide.

Recent esp version have 9 options on the visual micro board options menu. One of the options switches between serial upload and OTA.

The same also applies to the nodeMCU board.

Did you install your esp using the board manager or by unzipping into the sketchbook/hardware folder?

Check out this version: https://github.com/esp8266/Arduino/trunk
It is the upcoming next version

copy it to <ArduinoIDE>\hardware\esp8266com\esp8266\

and you will see that the option "Upload using: ..." is gone

"visual micro>always use programmer for upload" is not checked.

Thanks for the info. 

Last question. Was the Arduino Ide was also missing the OTA feature until you added it?

Sorry, I never used the Arduino Ide because VisualMicro is better  Wink
So I can't tell.

Arduino Ide is 1.6.5

OK, did a test, reverted my change in Boards.txt and it disappeared in Arduino Ide

Yes.

But perhaps it's good to see what your next problem will be when it becomes a release.  Wink

Hello,

I have exactly the same error. Using Arduino IDE I can do OTA update without problems.

Regards,

On arduino IDE, when an ota firmware is running in the ESP, under SerialPort appear a NetworkPort.

for me is it not present the Network port, so if you do not select the Network Port the OTA use the COM port and it do not work.

You have the networkport present ?

Hi,

You can install "Apple Bonjour for Windows" then the ports will automatically appear. It's quite a commonly used app but I don't bother with it ....

OR easier ...

You can enter a known IP address in the Visual Micro "Project Properties>Upload Port".

whit Arduino IDE it is not necessary the Apple sw, it is only necessary phyton 2.7.1.1 installed

VisualMicro cannot work in the same way ?

p.s. thanks for the manual tip

No visual micro doesn't use python that's new for the esp8266. 

We use C# and historically it's only been the Arduino Yun that required ip discovery. The Arduino Ide also requires "Apple Bonjour for Windows" to be installed when uploading to the Yun.

It is the esp8266 guys who have released the python alternative and in the not too distant future it it probably makes sense for Visual Micro to use python which is becoming very popular.

It's quite easy to find the ip addresses on a network and hopefully you read my note about adding the Ip address to the "Upload Port" property and your OTA is working?
