johnb 0:b0f8e1a438e0 58 This function is generally used when employing the non-blocking API in order to
johnb 0:b0f8e1a438e0 59 kick off the process of retrieving the data. Once the request has been sent
johnb 0:b0f8e1a438e0 60 the method returns and the response is processed asynchronously. Once received
johnb 0:b0f8e1a438e0 61 the data's available via the getXXX methods.
johnb 0:b0f8e1a438e0 62
johnb 0:b0f8e1a438e0 63 In the case that the blocking API is used the requestXXX methods are optional
johnb 0:b0f8e1a438e0 64 because the getXXX methods will send the request and then block until the response
johnb 0:b0f8e1a438e0 65 is received. The main potential advantage to still (selectively) using the requestXXX
johnb 0:b0f8e1a438e0 66 methods even when employing the blocking API is timing - the getXXX functions do not
johnb 0:b0f8e1a438e0 67 have to communicate with the XBee and can use the previously retrieved data
johnb 0:b0f8e1a438e0 68 meaning that there is no need to block on a communication exchange */
