Can anyone please define for me what are the differences between GATT and ATT? I didn't manage to understand.
I know that they are both generic protocol to handle BLE services. but didn't really understand it. Please explain.
Thanks!
ATT is a much lower level mechanism that basically defines how to transfer a unit of data (an attribute). GATT is built on top of ATT and defines how higher level services are composed and the framework for operating on those services.
