Your lucky day:

> ESP32 Arduino core from here: [https://github.com/espressif/arduino-esp32](https://github.com/espressif/arduino-esp32) by default runs the RF/radio/protocols on CORE0 while the Arduino code runs on CORE1. For most scenarios, this scheme works reasonably well. I reworked Neil Kolban's example a few years ago for an article I wrote, I think it simplifies things la bit by using an Arduino multi-tab example: /\* This sketch runs the same load on both cores of the ESP32 ArduinoIDE 1.8.5 Linux Mint 18.3 Sketch uses 162569 bytes (…

Yes, the ESP32 has 3 cores.
