Detailed Description
The Read Blob Response is sent in reply to a received Read Blob Request and contains part of the value of the attribute that has been read.
If the offset requested is equal to the length of the attribute then the response contains no data and the size of the data returned is equal to 0.
If the value of the attribute starting at the offset requested is longer than (mtu - 1) octets then the first (mtu - 1) will be present in the response. The remaining octets will be acquired by another Read Blob Request with an updated index.
