This new GATT protocol implements the following features:

  • chunking of big messages
  • creating a chunk header
  • reassembling of chunks
  • creating a flow control protocol tracking, reordering, resending chunks
  • split very large messages into smaller message parts before chunking
  • Dynamically adjust chunk size to MTU size
