I am looking for a good ESP32 audio development board to use for I'm using the ESP32 for an internship project, and I wanted to know if it was possible to use the mesh network of the ESP for sharing audio sent via bluetooth. If the channel is set to 0, data will be sent on the current channel. Extra. That is a broadcast address and you're giving up ACK packets and retransmittng at lower speeds (so you're giving up some range), but you're getting crazy speeds. Note that if AEC is not required, then there is no need for This sketch demonstrates how to receive broadcast messages from a master device using the ESP-NOW protocol. c -> void app_main will be triggered when you install the software on ESP32; nerdy_mac_address —provides a mac address of the device. 將 An example of recording audio onto a MicroSD card, using an INMP441 microphone and a XIAO ESP32-C3.
