[Ivan Voras] shows how to use interrupts to service the ESP32 analog to digital converters when sampling sound. Interestingly, he uses the Arduino IDE mixed with native ESP-IDF APIs to get the ...

Arduino boards get a Bluetooth Smart dev kit from Nordic Semiconductor. The SDK is compatible with a range of Arduino, ChipKIT shields that employ the nRF8001 Bluetooth Smart connectivity device.

As [bdring] explains, Grbl pushes the capability of the Arduino ... would nuke Bluetooth and Wi-Fi so obviously not an ideal solution. Eventually he figured out how to get interrupts more or ...
