Using BLE 4.2 and DLE

Does the ESP32 support the DLE (Data Length Extension)? This is different than the MTU, in that DLE actually allows BLE packets up to 251 bytes, whereas (in my understanding) MTU just allows multiple packets to be combined to a larger payload size.

From this article: https://punchthrough.com/maximizing-ble ... ion-dle-2/[/url] it appears that using DLE on devices that support BlueTooth 4.2 can significantly improve bandwidth. Up to 50 KB/sec per the article, which is over 10X faster than the best throughput I have been able to get on the ESP32 and an iPad.

Any information is appreciated.

Phil.
