Looks like they are working on it. https://github.com/platformio/platform-espressif32
@ivankravets any ETA?

[ivankravets]

We are waiting for ESP32 Dev Kits from Espressif System to test it. Espressif System has alerady shipped. 1-2 weeks...

[Testato]

Will platformio support the arduino core for esp32 and the espressif sdk also ?

[ivankravets]

Sure, see https://github.com/platformio/platform-espressif32/blob/develop/platform.json#L23:L32

Is this worth trying out yet? I have a SparkFun ESP32 Thing here and would be willing to test...

Well, to answer my own question, on PlatformIO, version 3.1.0, I tried installing platform-espressif32 manually and a blink sample builds but fails to link like this:

@blackketter need to sync https://github.com/platformio/platform-espressif32/blob/develop/builder/main.py#L72 with https://github.com/espressif/arduino-esp32/blob/master/platform.txt

[ivankravets]

Update! You can try initial implementation by @valeros. See https://github.com/platformio/platform-espressif32

The build results: https://travis-ci.org/platformio/platform-espressif32

[blackketter]

Awesome, blink builds, uploads and runs on my Sparkfun ESP32 Thing. I do find that I need to manually reset it after an upload, will look into that...

@ivankravets it looks like not all -D flags are set correctly: https://travis-ci.org/blynkkk/blynk-library/jobs/177357568

[ivankravets]

@vshymanskyy Thanks! Fixed in https://github.com/platformio/platform-espressif32/releases/tag/v0.1.1

P.S: v0.1.1 is released, just restart a Travis.CI Job.

[vshymanskyy]

Thank you! Fixed.
