Arduino Nano ESP32 Multiple Board Project Setup

Development Platforms
3

Hello! Something got lost in translation with the question marks :grin: but I was able to get it working with a merge of what you had and what I had.

[env:arduino_nano_esp32]
platform = espressif32
board = arduino_nano_esp32
framework = arduino
build_src_filter = -<*>

[env:Sender]
platform = espressif32
board = arduino_nano_esp32
framework = arduino
build_src_filter = +<Sender.cpp>
upload_port = /dev/cu.usbmodem3485187ABD482
monitor_port = /dev/cu.usbmodem3485187ABD482

[env:Receiver]
platform = espressif32
board = arduino_nano_esp32
framework = arduino
build_src_filter = +<Receiver.cpp>
upload_port = /dev/cu.usbmodem3485187AA41C2
monitor_port = /dev/cu.usbmodem3485187AA41C2

The arduino_nano_esp32 environment does not build successfully but I am not worried about it.

Thank you again!
