Some information is collected here. You need to configure:

    NRF_SDH_BLE_GAP_DATA_LENGTH 251
    NRF_SDH_BLE_GAP_EVENT_LENGTH 400 //not necessary, depends on application requirements
    NRF_SDH_BLE_GATT_MAX_MTU_SIZE 247

This will change the ram start and size settings for the application. So those will also have to be updated

Hi Thanks for quick reply.

Yes, I see the ble_app_att_mtu_throughput example. But it seems like working on peripheral and central example. Is there any other example code available or any service support the data length extension or any documentation?

Hi,

Have you looked at: nRF5_SDK_15.2.0_9412b96\examples\ble_central_and_peripheral\experimental\ble_app_att_mtu_throughput

Example documentation here.
