First boot & Wi-Fi setup

The device starts an open access point named ESP32-RTSP-Mic-AP. Connect to it and enter your Wi-Fi SSID and password in the captive portal. The board saves your settings and rejoins your network.

If the portal does not open, visit http://192.168.4.1. Then reconnect to your normal network. Find the board’s IP in your router, or use its unique mDNS name, such as esp32mic-a1b2c3.local, shown in its Web UI.

Connect to BirdNET

After Wi-Fi setup, add the device’s RTSP stream to BirdNET-Go or BirdNET-Pi.

rtsp://<device-ip>:8554/audio1
rtsp://<device-ip>:8554/audio2

These paths also work with the device’s unique mDNS hostname when mDNS is available.

How are downloads counted?

One complete firmware file transfer counts as one download. USB flashing counts only the app image; bootloaders and partition files are excluded. Device OTA and direct downloads are counted separately. Retries and repeat downloads can count again; these numbers do not measure unique devices or successful installations.

Website history is limited to retained server logs. GitHub totals cover published firmware assets.

Website checks by our release scripts, HEAD requests, failed and incomplete transfers are excluded. GitHub provides raw asset download counts, including historical tests and automation that cannot be separated. A release’s total adds its four boards and all download types. Historical transfers whose version cannot be verified are listed as “Unassigned”.
