    Data Length Extension (DLE) API in Bluetooth middleware: setting data length?

    JaPo_3883311

      Background: Using a PSoC 6 MCU as a BLE GATT server and trying to use Data Length Extension (DLE).

       

      The Bluetooth Low Energy PDL docs define the following event:

      CY_BLE_EVT_SET_DATA_LENGTH_COMPLETE: This event indicates completion of the Set data length command.

      But I don't see any set data length command in the API. It only has a function for getting the data length (Cy_BLE_GetDataLength) which triggers an analogous event (CY_BLE_EVT_GET_DATA_LENGTH_COMPLETE). This asymmetry strikes me as a a sign of incompleteness. Is the nonexistent set data length function in development or something?

       

      I also don't see a command corresponding to CY_BLE_EVT_SET_SUGGESTED_DATA_LENGTH_COMPLETE, but maybe I'm missing it because the PDL docs' search function only returns items that match from the start of the string, making it basically unusable.

       

      Hopefully this has a simple answer I'm just being an idiot here.
