LP-EM-CC2340R5: how to automatically connect peripheral to central

I want connect like without menu 

so my board will connect automatically if device(peripheral) found at the time of scanning will be start.  

my query is not like that.

I want to know how to scan automatically when board is on or power up. like that without menu

regards

Hello Umesh,

I would suggest checking the Scanning and Advertising basics SLA and see if that is a good starting point for you.

What is not working for you exactly?

Best regards,

David.

I want scan directly without any menu or press button.

Automatically start scanning power-up.

Hello Umesh,

I assume you are working with the basic_ble project and that you have modified the project for peripheral and central as mentioned in the thread Central to Peripheral Automatically Connect.

The modified app_central.c can start scanning without menu after power up by adding the following to the Central_Start() function.

status = BLEAppUtil_scanStart(&centralScanStartParams);
    if(status != SUCCESS)
      {
          // Return status value
          return(status);
     }

Have you tried this? What exactly is not working?

Best regards,

David.

Hello David,

Thankyou for your reponse, but have I already tried this one but that is not working.

So when my board is powered-up that time I am pressing  the button and scanning  will start that is predefine but I want to work  my board as soon as I  powered-up at the same  time scanning should start automatically.

So now what is  happening  I am going to tis file app_menu.c and calling  to menu_start() function.

I have mentioned it below for your reference. 

bStatus_t Menu_start()
{
  bStatus_t status = SUCCESS;

#if !defined(Display_DISABLE_ALL)
  MenuModule_params_t params = {
#if ( HOST_CONFIG & ( CENTRAL_CFG | OBSERVER_CFG | PERIPHERAL_CFG ) )
    .mode = MenuModule_Mode_MENU_WITH_BUTTONS
#else
    .mode = MenuModule_Mode_PRINTS_ONLY
#endif // #if ( HOST_CONFIG & ( CENTRAL_CFG | OBSERVER_CFG | PERIPHERAL_CFG ) )
  };

#if ( HOST_CONFIG & ( CENTRAL_CFG | OBSERVER_CFG | PERIPHERAL_CFG ) )
  status = MenuModule_init(&mainMenuObject, &params);
#else
  status = MenuModule_init(NULL, &params);
  if(status == SUCCESS)
  {

    // Print the application name
    MenuModule_printf(APP_MENU_GENERAL_STATUS_LINE, 0,
                      MENU_MODULE_COLOR_BOLD MENU_MODULE_COLOR_CYAN
                      "Basic BLE" MENU_MODULE_COLOR_RESET);
  }
#endif // #if ( HOST_CONFIG & ( CENTRAL_CFG | OBSERVER_CFG | PERIPHERAL_CFG ) )

#endif // #if !defined(Display_DISABLE_ALL)
  return status;
}

than after calling the function  MenuModule_init(&mainMenuObject, &params); then the  function below is getting called 

//*****************************************************************************
//! Globals
//*****************************************************************************
#if ( HOST_CONFIG & ( CENTRAL_CFG | PERIPHERAL_CFG ) )
// The current connection handle the menu is working with
static uint16 menuCurrentConnHandle;
#endif // #if ( HOST_CONFIG & ( CENTRAL_CFG | PERIPHERAL_CFG ) )

#if ( HOST_CONFIG & ( CENTRAL_CFG | OBSERVER_CFG ) )
// Scan Menu
const MenuModule_Menu_t scanningMenu[] =
{
 {"Scan", &Menu_scanStartCB, "Scan for devices"},
 {"Stop Scan", &Menu_scanStopCB, "Stop Scanning for devices"}
};

MENU_MODULE_MENU_OBJECT("Scanning Menu", scanningMenu);
#endif // #if ( HOST_CONFIG & ( CENTRAL_CFG ) )

#if ( HOST_CONFIG & ( CENTRAL_CFG | PERIPHERAL_CFG ) )
// Connection Menu
const MenuModule_Menu_t connectionMenu[] =
{
#if ( HOST_CONFIG & ( CENTRAL_CFG ) )
 {"Connect", &Menu_connectCB, "Connect to a device"},
#endif // #if ( HOST_CONFIG & ( CENTRAL_CFG ) )
 {"Work with", &Menu_workWithCB, "Work with a peer device"}
};

MENU_MODULE_MENU_OBJECT("Connection Menu", connectionMenu);

// Work with menu
const MenuModule_Menu_t workWithMenu[] =
{
 {"Change conn phy", &Menu_connPhyCB, "1M, Coded or 2M"},
 {"Param update", &Menu_paramUpdateCB, "Send connection param update req"},
 {"Disconnect", &Menu_disconnectCB, "Disconnect a specific connection"}
};

MENU_MODULE_MENU_OBJECT("Work with Menu", workWithMenu);

// Phy selection menu
const MenuModule_Menu_t connPhyMenu[] =
{
 {"1 Mbps", &Menu_connPhyChangeCB, ""},
 {"2 Mbps", &Menu_connPhyChangeCB, ""},
 {"1 & 2 Mbps", &Menu_connPhyChangeCB, ""},
 {"Coded", &Menu_connPhyChangeCB, ""},
 {"1 & 2 Mbps & Coded", &Menu_connPhyChangeCB, ""},
};

MENU_MODULE_MENU_OBJECT("Set Conn PHY Preference", connPhyMenu);

#endif // #if ( HOST_CONFIG & ( CENTRAL_CFG | PERIPHERAL_CFG ) )

// Main menu
#if ( HOST_CONFIG & ( CENTRAL_CFG | OBSERVER_CFG | PERIPHERAL_CFG ) )
const MenuModule_Menu_t mainMenu[] =
{
#if ( HOST_CONFIG & ( CENTRAL_CFG | OBSERVER_CFG) )
 {"Scanning", &Menu_scanningCB, "Scan menu"},
#endif // #if ( HOST_CONFIG & ( CENTRAL_CFG | OBSERVER_CFG ) )
#if ( HOST_CONFIG & ( CENTRAL_CFG | PERIPHERAL_CFG ) )
 {"Connection", &Menu_connectionCB, "Connection menu"},
#endif // #if ( HOST_CONFIG & ( CENTRAL_CFG | PERIPHERAL_CFG ) )
};

MENU_MODULE_MENU_OBJECT("Basic BLE Menu", mainMenu);
#endif // #if ( HOST_CONFIG & ( CENTRAL_CFG | OBSERVER_CFG | PERIPHERAL_CFG ) )

Then this function is getting called  MENU_MODULE_MENU_OBJECT("Connection Menu", connectionMenu);  and then I  press the  button and scanning will start. But I don't want this one I want scanning to be started automatically when powered-on.

Hello David,

 I tried disable the Display Module but scanning is  not working.

So in that case can I call directly scan function?
