Hi, the Data Length Extension (DLE), a feature from Bluetooth 4.2 (as I understand this is the LL_LENGTH_PDU, am I correct?) is supported on newer phones with Android 6*, as far as I remember. There is no any API to enable or disable it. Android will use it if MTU > 23 and both sides support it. Android only allows to request MTU, which the library is doing, as this is now supported by the DFU bootloader since SDK 15.
* Newer phones = some phones got update to Android 6 and they may not support it.

Hi ,
This is good news!
However my peripheral requires the central to explicitly request that the PDU length be extended via
a LL_LENGTH_REQ.
My peripheral is mbed based, however would a Nordic peripheral no also require such a request before it would extend the PDU length?

@philips77 has his been answered in DevZone, can you share any reference.
We were using NRF52 - would like to know - from iOS/Android phones how to do MTU negotiation v/s PDU size.
