    About the maximum size of data that can be notified by Notification of PSoC63 device


      I am implementing BLE Notification on a PSoC63 device.

      API of "Cy_BLE_GATTS_SendNotification" is used, but API returns "CY_BLE_ERROR_INVALID_PARAMETER" error when data is 20 bytes or more.

      If the data is less than 20 bytes, it will be notified correctly.

      Where should I modify to send 20 bytes or more data?


      I am using the following development environment.

      ・PSoC Creator : 4.2

      ・PDL : 3.0.4

      ・Device : CY8CPROTO-063-BLE


      Best regards.
