+/**
+ * This is an example program that's using the SimpleBLE library
+ * to expose some variables to the outside world using BLE.
+ * Written by Jan Jongboom (jan.jongboom@arm.com)
+ */
+
+#include "mbed.h"
+#include "SimpleBLE.h"
+
+// The first thing we need to do is create a SimpleBLE instance:
+// * first argument is the device name
+// * second is the advertisement interval in ms. (default 1000 ms.)
+SimpleBLE ble("DEVICE_NAME", 1000);
+
+// Now we can declare some variables that we want to expose.
+// After you created the variable you can use it like any other var,
+// but it's value will be automatically updated over Bluetooth!
+
+// F.e. here we declare service 0x180d (heartrate), char 0x2a37 (curr. value) as uint8_t
+SimpleChar<uint8_t> heartrate = ble.readOnly<uint8_t>(0x180D, 0x2A37, true /* notify */, 100 /* default value */);
+
+// now we can use this variable everywhere in our code like a normal uint8_t
+void updateHeartrate() {
+    // we just loop between 100 and 180
+    heartrate = heartrate + 1;
+    if (heartrate > 180) {
+        heartrate = 100;
+    }
+}
+
+// And here we create a custom service (0x9310) and char (0x9311) with a callback
+void callback(uint32_t newValue) {
+    // whenever someone updates this var over Bluetooth, this function will be called
+    printf("My value was updated to %d\n", newValue);
+}
+// FYI, you can also use UUIDs here instead of short services :-)
+SimpleChar<uint32_t> writeMe = ble.readWrite<uint32_t>(0x9310, 0x9311, &callback);
+
+int main(int, char**) {
+    // update the heart rate every second
+    Ticker t;
+    t.attach(updateHeartrate, 1.0f);
+    
+    // here's how we kick off our loop
+    ble.start();
+    while (1) {
+        ble.waitForEvent();
+    }
+
