I am working on embedded linux platform and I want to increase data length in BLE communication but I can't find an api function to change data packet length. The module used is SparkLAN AP6256. Is there any configuration parameter to enable DLE (Data Length Extension).

Currently I am using gattool to connect to the device (configured as ble device) and the data length is set to 23 bytes by default. Also tried using btgatt-server and btgatt-client but didn't see any option to enable DLE.
