s132 maximum throughput

Hello There,

As mentioned in the S132 specification (S132_SDS_v0.5.pdf), when acted as a peripheral and the connection time interval is 7.5ms, for the case of a GATT server, the maximum throughput values are:

a) Send Notification 42.6 kbps

b) Simultaneous send Notification and receive Write command 50.8 kbps (each direction)

I have 3 questions:

  1. Since 2x20x8/0.0075=42666.6 kps, so the maximum number of packets that could be sent at each connection is 2, is that correct?

  2. Why the throughput in b) is larger than that in a) ?

  3. Can I assume the same throughput values for S332?

Regards, Joseph
