+  SigFox Send Boolean tutorial
+
+  This sketch demonstrates how to send a simple binary data ( 0 or 1 ) using a MKRFox1200.
+  If the application only needs to send one bit of information the transmission time
+  (and thus power consumption) will be much lower than sending a full 12 bytes packet.
+
+  This example code is in the public domain.
