+ * @text The example shows how the SDP Client is used to get a list of 
+ * service records on a remote device. The address of the remote device is 
+ * fixed in the variable remote below.
+ * The SDP Client returns the results of the query in chunks. Each result
+ * packet contains the record ID, the Attribute ID, and a chunk of the Attribute
+ * value.
