@ -41,9 +41,9 @@ The following SpanPoint methods are used to transmit and receive messages from a
* if a message is available, it is **moved** from the internal message queue into *dataBuf* and the method returns **true**
* the size of the message will always be equal to the *receiveSize* parameter specified when the SpanPoint object was created, so make sure *dataBuf* is sufficiently sized to store such a message
Note that whether or or not you call the `get()` method, SpanPoint is configured to store in an internal queue any SpanPoint messages it receives from *other* devices, provided that (a) there is room in the internal queue, and (b) the size of the message received matches the *receiveSize* parameter specified when the relevant SpanPoint object was instantiated. Each SpanPoint object maintains its own internal queue, which can be set tro hold more than one message by setting the *queueDepth* parameter to something greater than 1 when instantating the SpanPoint object.

If the internal queue is full when a message is received, the message is not moved to the queue and will thus never be retrievable by the `get()` method. Regardless of whether or not the queue if full, if the size of a received messages does not match the *receiveSize* parameter specified for this instance of the SpanPoint object, the message will be discarded and if *receiveSize* is greater than zero, a non-fatal run-time warning about size mismatches will be output on the Serial Monitor.
