 Once you have the device's MAC address, create a MetaWear object with the MAC address and connect to the device.
 
 .. code-block:: python
 
     device = MetaWear(address)
-    status = device.connect()
+    device.connect()
 
 Upon a successful connection, you can begin calling any of the functions from the C++ SDK, for example, blinking the LED green.
