PlatformIO, version 4.0.0a3
MacOS 10.14.3
In my platformio.ini file, I have the serial port for my device defined as upload_port = /dev/cu.usbserial-14413440, which matches what I see in ls /dev/cu.* output and matches what I see in pio device list:
/dev/cu.usbserial-14413430

Hardware ID: USB VID:PID=1A86:7523 LOCATION=20-4.1.3.4.3
Description: USB2.0-Serial
However, when I try to upload my project (an ESP8266/Arduino project), PIO tries to upload via OTA. This is a new problem. Just 3 days ago, uploading by serial worked fine. I did not make changes to the platformio.ini file in that time.
Iām not sure what the issue is, but is there a way to force PIO to perform serial upload? Iāve also tried with the tty version of the port (/dev/tty.usbserial-14413430), but it has the same issue.
What command are you using for uploading? Via the CLI or an IDE? What is the verbose output of that procedure?
Happens in both IDE (VSCode) and CLI, using command pio run --target upload.
The non-verbose output is:
Configuring upload protocol...

I just tried to enable verbose, and now it correctly finds the serial port and uploads properly. I made no changes to the code or settings, the host computer was not even restarted, the hardware (NodeMCU) was not uplugged. Odd.
Can you show your full platformio.ini?

This happens on Windows platforms too and is a serious issue.
The new 2.0.x releases appear to break the upload_port setting in platformio.ini: it looks like it now interprets the upload_port as an IP address instead of a COM port. This is very easy to reproduce: for example, using the auto-generated platformio.ini configuration and adding just the upload port specification:
[env:esp12e]
platform = espressif8266
board = esp12e
framework = arduino
upload_port=COM5
Attempts to upload to target now result in:

Any ideas? I didnāt see anything helpful in the release notes. How do I tell it to use a specific serial port for upload? (Note: if no upload port is specified, it auto-detects the first serial port, but thatās not the one I need to use).
I cannot reproduce this on my Windows PC.

Can you try via the terminal?
Same problem when run from the terminalā¦it is 100% reproducible. If I comment out the upload_port (and the target is the first serial port), it uploads over serial. However if I un-comment that line, it attempts an OTA upload.

Time to compare versions then. Can you please upgrade the core to the latest dev version using pio upgrade --dev in the terminal? Also whatās the platform-esp8266 version when you type in pio platforms show espressif8266? Itās Version: 2.0.1 for me.
Itās 2.0.1 for me too. Note: Iāve tried falling back to 2.0.x and it has the same issue.

There is a suspicious commit Branch for espota if port resolved (#97) Ā· platformio/platform-espressif8266@54cd0fb Ā· GitHub which might have caused this. The previous logic only allowed IP address strings to be OTA upload ports. The new logic checks if it can resolve the name. Can you try to write upload_protocol = esptool in the platformio.ini?
You might also try to platform = espressif8266@1.8.0 where this commit wasnāt yet present.
Iāll try that. I should mention in case itās related that Iām getting a task error when I launch the upload:
Error: The PlatformIO task detection didnāt contribute a task for the following configuration:
{
ātypeā: āPlatformIOā,
ātaskā: āUpdate installed platforms, packages and librariesā,
āproblemMatcherā: [
ā$platformioā
]
}
The task will be ignored.
The commit you mentioned certainly looks like the problem.
1.8.0 worked fine (although I had to change some other code that is incompatible between 1.8.0 and 2.0.x (I access the main task to get the stack size and cont.h has changed).
After pio upgrade --dev, I canāt seem to access the platforms anymore; how do I roll back to release version?
What exact error message did you get? Do you have two PIO cores installed maybe? (VScode-internal and one externally installed via pip?)
When I try to access the platforms from PIO home, I just get the loading circle indefinitely. How do I get off the development branch?
(and no,Iāve installed nothing via pip)
Well thereās no integrated way to get back :S. Restart the IDE maybe? Iād just re-install the plugin from scratch if it doesnāt work.
Never mind, restarting VSCode cleared the problem with accessing the Platforms. Iāll try again with 1.8.0
platform = espressif8266@1.8.0 works as expected (properly with upload_port=COM5)
It fails with platform = espressif8266@2.0.0 or 2.0.1
ā¦and I think you nailed the problem commit. Is there any easy way for me to patch that locally until it gets resolved?
BTW, thanks so much for all of your help!

I think too. Now the real next question is why the python code socket.gethostbyname("COM5") doesnāt throw a socket.error exception for you, preventing an OTA upload. Can you ping COM5 or nslookup COM5 on the command line just for fun? Part of the problem is also that this is somehow a resolvable name for your PC.
When using the newer platform version youād have to manually fix the platform-espressif8266/builder/main.py unfortunately 
.
