Thanks a lot for such a detailed overview! There is just one thing I don’t get yet. It is DLE vs ATT MTU. In the example you gave - Optimizing throughput Example, you showed how to increase the throughput by increasing the connection interval so it will be aligned with LL packet transfer time, and you reached 5 full LL packets 251 byte each per connection interval. But if the maximum ATT MTU is 512 byte, this means that we can only utilize 2 full LL packets and 10 byte from another LL packet per one GATT characteristic in one connection interval. So if I get it correctly the full LL throughput utilization in example you gave I can only achieve when I have several GATT characteristics?
Thanks again.
