ESP32 Dual Core with Arduino IDE | Random Nerd Tutorials
November 26, 2025 - For my project I currently use Arduino (controls etc) and ESP8266 (Wifi) with RX/TX links but would like to investigate the 2 x core ESP32 option Reply · Hi Bob. We don’t go deep into that subject in our course. As Tony mentioned in a previous comment “both tasks can use the same variables declared in the sketch, so this is the easiest way to communicate between the cores.”. I hope this helps.

Creating a Thread/Matter device with ESP32 C6 and Arduino Core · Issue #9240 · espressif/arduino-esp32
February 13, 2024 - Using Espressif ZeroCode is no option, since the ESP32 C6 seems not to be supported (why???). Using the Espressif IDF would be another option, but seems to be much more complicated than using the Arduino Core.

OpenThread - - — Arduino ESP32 latest documentation
Arduino OpenThread sketches read ESP-IDF sdkconfig symbols (CONFIG_OPENTHREAD_*). The ESP-IDF OpenThread port maps many of them to OpenThread core macros (OPENTHREAD_CONFIG_*) in openthread-core-esp32x-ftd-config.h. Some library features also depend on macros that are not direct menu toggles and must be set in a custom OpenThread header when using Arduino as an ESP-IDF component. CoAPS builds: enable Thread Extensioned Features → Use a header file defined by customer, define OPENTHREAD_CONFIG_COAP_SECURE_API_ENABLE 1 in that header, and enable mbedtls PSK ciphers — see README.md.

Setting up RTOS for dual-core and multi-threaded operation
On a single core, often, one thread has to wait for the other to pause before it can begin execution. On two cores, parallel execution is literally parallel, because they are literally occupying different processors. Sounds exciting? Let's get started with a real example, that demonstrates how to create two tasks and assign them to specific cores within ESP32. ... To use FreeRTOS within the Arduino ...

r/esp32 on Reddit: Easy threading on the ESP32
July 29, 2022 -
It's really difficult to chase down race conditions, even with a debugger.
Because of that, you may hesitate to use the secondary core on applicable ESP32s.
I've created a PlatformIO library to make it almost foolproof to write code that targets the secondary core or just a secondary thread on the primary core.
The library is easy to use and examples are included.
Add this to your platformio.ini
lib_ldf_mode = deep lib_deps = codewitch-honey-crisis/htcw_freertos_thread_pack
Or visit this link to download the code manually (necessary if using Arduino IDE)
https://github.com/codewitch-honey-crisis/htcw_freertos_thread_pack
Included is a thread class, a thread pool class, a thread safe message queue class, and something called a "synchronization_context". The latter was a concept I "borrowed" from .NET that allows you to dispatch code on a waiting thread. Basically you feed it a lambda from the primary thread and it will run whatever code was inside of it on the thread that's waiting. It often makes it unnecessary to roll your own synchronization.
Examples are included under /examples

r/esp32 on Reddit: ESP32 device with thread (matter) support?
January 9, 2023 -
Are there any ESP32 devices which support thread (matter)? And in addition, are there any libraries like homespan which can be used for building such a device to be used with apple HomeKit?

Matter sdk is available on esprissif idf, but I have no idea if thr support is added to arduino ide(I think so not). And matter splution can work with you esp32-c and s series. But the thread devices like esp32-h2 is still not avaible.
