bool connectToPinPad()

This function begins a connection to the Bluetooth PIN pad. The device must be turned on before the function is called, or the connection attempt will fail. After calling it, getIsBusy() should be called on a timer until it returns false. A connection must be opened to the PIN pad before any transaction is run. This function can safely be called, even when a connection is already open.

Return

True if success, false otherwise.
