johnb | 0:b0f8e1a438e0 | 55 | This function is generally used when employing the non-blocking API in order to |
johnb | 0:b0f8e1a438e0 | 56 | kick off the process of retrieving the data. Once the request has been sent |
johnb | 0:b0f8e1a438e0 | 57 | the method returns and the response is processed asynchronously. Once received |
johnb | 0:b0f8e1a438e0 | 58 | the data's available via the getXXX methods. |

johnb | 0:b0f8e1a438e0 | 63 | methods even when employing the blocking API is timing - the getXXX functions do not |
johnb | 0:b0f8e1a438e0 | 64 | have to communicate with the XBee and can use the previously retrieved data |
