Subscribe to the DroneBot Workshop Newsletter and be the first to find out about new projects and new features on the website. Serial Bridge Using ESP32. My question is, will it be possible to use one core of ESP32 to run the clock mechanism, and another core to control LED animation (so the clock is not waiting in the meantime). [AdaGFX helper] Fix a missing conditional compilation check Im sure you can see how useful this will be when developing your own Bluetooth applications. I had issues with the repeat timer as well, and I traced it to the push button code that checks for LOW and changed it to HIGH (Im guessing this is due to a different type of push button being used N/C vs N/O). I am tinkering with an ESP32-DEVKITC-32D-F ($10 from DigiKey) and I ran into an issue using Arduino on my Mac. If you look online for instructions for setting up the IDE you may run into a long and complex procedure that actually isnt necessary anymore. [P037] Optimize string handling/passing [P037] Actually store the NaN value if applicable As its name would indicate Classic Bluetooth has been around for quite a while and is likely the Bluetooth that you are most familiar with. It should also be possible to use a separate SD card support. To test the code, simply compile it and upload it to your ESP32 board.
