Error on ESP8266 OTA in VisualStudio 2017

Hi,

I'm trying to use OTA to upload my sketch out of VisualStudio 2017.
I have a working sketch and even the OTA Upload is possible when I use the Arduino IDE to upload.
When I use the same sketch in VMicro the ESP is not detected. (Bonjour is not installed) To overcome this I have put in the (correct) IP-Adr. into the port box. When I now hit upload i get the following error:

Code
Select All
Uploading 'wlanManager_n_OTA' to 'NodeMCU 1.0 (ESP-12E Module)' using '192.168.178.40'
The uploader returned an error
Usage: espota.py [options]
espota.py: error: option -p: invalid integer value: '{network.port}'


I can't find a solution for that. Running VS as Admin or disabling the firewall doesn't help.

VMicro Version is: 1709.6.0
Python 2.7 is installed and in the path.

I'm confused about the error message. "Invalid integer..."

Best regards,
  MrLight

Hi,

The error is because you have not provided the IP port that the esp is waiting on. You will see that your esp code will probably use the default esp example of 8266

You should also provide authentication setting, especially if you configure a password in your esp code.

Both the port and password can be supplied in a board.txt that can be added to your project. You will see an example of how to do that at the end of the esp8266 documentation page on visualmicro.com

It's something like this:-

Code
Select All
  network.port=8266


and with password like this:-

Code
Select All
  network.port=8266
  network.password=123
  network.auth_upload=yes


tip: when you make changes to a board.txt click save before build/upload. VS does auto save but after the build/upload has completed ( can be confusing ).

ahhh... Thank you very much for that fast answer!

Everything is working fine now. I have always tried to use IP:port... 

THX! MrLight

Great thanks for the update.

ip:port, that's a natural idea  Smiley  I guess I should support that. Will try to add to future releases
