Advertise a BLE Service
Expose your ESP32 so a phone can find it.
Make Your Board Findable
Before a phone can connect, your ESP32 must announce itself. This shouting into the air is called advertising. 📣
What Advertising Sends
Advertising broadcasts tiny packets with your device name and what it offers, so nearby phones can list it without connecting yet.
