This article describes modification of Arduino NINA firmware to wirelessly transmit I2S microphone data.
Uncompressed 32bit 44.1kHz audio transmission wirelessly is not possible from Arduino MKR WiFi 1010 with existing NINA firmware and WiFiNINA library due to latency introduced by its communication protocol. This article describes minor modifications to firmware enabling high data-rate UDP transmissions.
