I am having an oddity of some sort with OTA. I Pulled the BasicOTA Sample into the Arduino IDE and it works fine.

Then I close the IDE and open it is VS2017 with VM, and the same code fails....

Sometimes, occasionally, it will work once, but usually just fails. It's never worked a second time in VS, today.

This worked fine previously... (Well, OTA can be a bit finicky, but worked as fine as ever).

I assume this is the code catching the error:

  ArduinoOTA.onError([](ota_error_t error) {
    Serial.printf("Error[%u]: ", error);
    if (error == OTA_AUTH_ERROR) Serial.println("Auth Failed");
    else if (error == OTA_BEGIN_ERROR) Serial.println("Begin Failed");
    else if (error == OTA_CONNECT_ERROR) Serial.println("Connect Failed");
    else if (error == OTA_RECEIVE_ERROR) Serial.println("Receive Failed");
    else if (error == OTA_END_ERROR) Serial.println("End Failed");
  }); 

Any hints? Is there a simple way to reload the ESP toolchains and utilities?

Don't care about debug, particularly.
Need OTA to work though. Release does the same thing.
I need to use Serial for a RFID reader and it's a pain to swap wires. .... and it worked before the last update. Something of some sort has changed.

I have tried both.

Connected for power,

With all due respect, and as much as I love Visual Micro.

1. It worked before. Something changed.

2. It works just like it's supposed to in the Arduino IDE.

3. The Basic OTA Sample is about as simple as it gets for OTA. It should be pretty close to "just works".

It would seem to me that if it works in Arduino but not in VM, there is either a bug or a configuration error in my Visual Micro setup.

I do kind of depend on being able to compile in Arduino for those who may take my code and don't have VM.

In the Basic OTA example it was bonjour and/or typing the IP address directly in the combobox.

For the production sketch it was bonjour/mDNS with the p/w in the board.txt.

The sample has no password. Is a password "neeeded" to work?

Quote:

Yes. The sketch runs fine and puts the Serial.Print stuff to the serial window. Just OTA fails.

I have tried it with no serial monitor, using Putty as the serial monitor, and with the VM serial monitor. I don't recall the exact order when monitoring with VM, but I would guess serial is closed when the project opens. I can follow any steps you want.

Sorry for the delay.

I think this is resolved in the next release. If the usb driver on the serial defaulted RTS on then visual micro was not switching it off.

We didn't hit the issue but the code was wrong and probably affected you.

There has been a lot of testing with wemos esp32 + OTA combined with the WebManager project and it's been very reliable.

USB debug support has also been added. 

Thanks for the report.

Next release is here
