    UART - BLE project, CyBle_GattsNotification()



      I'm developing an application based on this UART TO BLE BRIDGE project:




      When data com from the UART interface, function CyBle_GattsNotification() is used to send data to the Central device.


      For small frames ( tested with 15-16 bytes), it's works well.


      For bigger frames ( tested with 24 bytes ), CyBle_GattsNotification() return an error ( CYBLE_ERROR_INVALID_PARAMETER ).

      • My MTU is bigger than 24 ( actually 300 set on GAP settings , BLE component )
      • Data characteristic size is bigger than 24 (30)

      Do you have any idea about this problem ? Why i can't send more datas ?
