Hi brain112,

GAPRole_SetParameter(GAPROLE_ADVERT_DATA, sizeof(advertData), advertData);
This function is designed to be called in the initialization state，so it may cause status errors when called in other stages.

You can use this function to update the advertising data:

/**
 * @brief   Setup or change advertising and scan response data.
 *
 * @note    if the return status from this function is SUCCESS,the task isn't complete
 *          until the GAP_ADV_DATA_UPDATE_DONE_EVENT is sent to the calling application task.
 *
 * @param   taskID - task ID of the app requesting the change
 * @param   adType - TRUE - advertisement data, FALSE  - scan response data
 * @param   dataLen - Octet length of advertData
 * @param   pAdvertData - advertising or scan response data
 *
 * @return  SUCCESS: data accepted
 *          bleIncorrectMode: invalid profile role
 */
extern bStatus_t GAP_UpdateAdvertisingData( uint8_t taskID, uint8_t adType, uint16_t dataLen, uint8_t *pAdvertData );

This function wiil send a message to a valid taskID, if you use the Peripheral_TaskID, you can handle the message here:

static void Peripheral_ProcessGAPMsg(gapRoleEvent_t *pEvent)
{
    switch(pEvent->gap.opcode)
    {
        case GAP_ADV_DATA_UPDATE_DONE_EVENT:
            PRINT("%s data update status: %#x\n",
                       pEvent->dataUpdate.adType ? "adv" : "scan", pEvent->dataUpdate.hdr.status);
            break;
        ...
