How about iPhone SE? Is it supposed to support data packet length extension, longer than the default 27 bytes?

If not, any plans to support this in the future?

The iPhone 6s tech spec state that it supports BT 4.2. Does that include the LE Data Packet Length Extension?

Specifically, can we expect an iPhone 6s, (iOS 9.3) to support negotiation of the maximum size via the exchange of LL_LENGTH_REQ_PDU & LL_LENGTH_RSP PDU¹s?

Thank you.
