    Monster,

    Since SPPLE is a custom service created to perform SPP over a BLE link, most apps don't support it natively. I would suggest downloading the LightBlue app and working through the section in the wiki page you referenced for getting data transfer.

    Best Regards,

    Vince

    Hi Sir,

    I want set Characteristic like CC2541 simpleperipheral. Please help check code.

    #define SIMPLEPROFILE_SERV_UUID 0xFFF0

    // Key Pressed UUID
    #define SIMPLEPROFILE_CHAR1_UUID 0xFFF1

    static BTPSCONST GATT_Primary_Service_16_Entry_tSPPLE_Service_UUID =
    {
    SIMPLEPROFILE_SERV_UUID
    };

    /* The Tx Characteristic Declaration. */
    static BTPSCONST _tagGATT_Characteristic_Declaration_16_Entry_t SPPLE_Tx_Declaration =
    {
    GATT_CHARACTERISTIC_PROPERTIES_NOTIFY|GATT_CHARACTERISTIC_PROPERTIES_WRITE|GATT_CHARACTERISTIC_PROPERTIES_READ,
    SIMPLEPROFILE_CHAR1_UUID 
    };

    /* The Tx Characteristic Value. */
    static BTPSCONST GATT_Characteristic_Value_16_Entry_t SPPLE_Tx_Value =
    {
    SIMPLEPROFILE_CHAR1_UUID ,
    0,
    NULL
    };

    Sending Data from LightBlue/Receiving Data in SPPLEDemo

    At this point the client (LightBlue) can send data to the server (SPPLEDemo). To send data from LightBlue to SPPLEDemo do the following:

    1. Open the Rx Characteristic (0x8B00ACE7-EB0B-49B0-BBE9-9AEE0A26E1A3).
    2. Choose Write new value.
    3. Type 414243 (ABC in ASCII).
    4. Choose Done

    Will trigger  SPPLE_RX_CHARACTERISTIC_ATTRIBUTE_OFFSET in GATT_ServerEventCallback when Lightbule Write new value?
