    How can I configure CYW20719 to use Data Length Extension?

      Hello,

      I have the CYW20719Q40EVB-01 board and am trying to conduct througput tests over BLE and BR/EDR between the board an a Sony Xperia XZ2 Compact (supporting Bluetooth 5). The problems I'm experiencing only regards BLE. When connecting to the device I'm setting the preffered PHY to LE_2M which returns SUCCESS but when I'm sending bigger chunks of data and calculate the throughput, it seems that the PDU-size has not been extended to enable 251 byte payloads. The carachteristics for transmitting data have been setup for 247 bytes.

       

      Is there a way to increase the Link Layer RX/TX payload size in wiced studio?

       

      Best regards
