+  Scan Callback
+
+  This example scans for BLE peripherals and prints out their advertising details:
+  address, local name, adverised service UUIDs. Unlike the Scan example, it uses
+  the callback style APIs and disables filtering so the peripheral discovery is
+  reported for every single advertisement it makes.
+
+  The circuit:
+  - Arduino MKR WiFi 1010, Arduino Uno WiFi Rev2 board, Arduino Nano 33 IoT,
+    Arduino Nano 33 BLE, or Arduino Nano 33 BLE Sense board.
+
+  This example code is in the public domain.
