    UART - BLE project, CyBle_GattsNotification()

      Hi,

         

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

         

      http://www.cypress.com/blog/100-projects-100-days/project-020-uart-ble-bridge.

         

      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 ?

         

       

         

      Regards,
