Arduino / ESP32 and nrf52840 donglehttps://devzone.nordicsemi.com/f/nordic-q-a/56732/arduino-esp32-and-nrf52840-dongleGood evening, after a very long research I couldn&#39;t find any answer. Is (and if, how) it possible to connect an Arduino (or ESP32) via SPI, I2C etc. with the nrf52840 dongle? I simply want to transmit data from the nrf52840 to my Arduino / ESP32en-USTelligent Community 13Mon, 20 Jan 2020 14:36:30 GMTRE: Arduino / ESP32 and nrf52840 donglehttps://devzone.nordicsemi.com/thread/229900?ContentTypeID=1Mon, 20 Jan 2020 14:36:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c1084d52-3fc0-4c4f-bbc8-8a2044f5367fKenneth<p>Currently there is no official Nordic support for the nRF52-series in Zephyr, however it should be possible to look at the i2c drivers and samples in Zephyr on how to use i2c as examples. Just search for paths that contain i2c.</p> <p>For development you should get an nRF52840-DK that contain a debugger.</p><div style="clear:both;"></div>
