BLE advertising not working

[Rajneesh]

Hello Everyone,

When i use malloc function in on_ble_event function ble advertising get stuck and not working

below is my implement code:

static void on_ble_evt(ble_evt_t * p_ble_evt) { uint32_t err_code; struct Addnode *rssi_node; int8_t strengthnew_signal = 0; bool new_addr = 0; bool f_match = 0; rssi_node = head;

switch (p_ble_evt->header.evt_id)
{
    case BLE_GAP_EVT_CONNECTED:
        err_code = bsp_indication_set(BSP_INDICATE_CONNECTED);
        APP_ERROR_CHECK(err_code);

        m_conn_handle = p_ble_evt->evt.gap_evt.conn_handle;
        
        break;

    case BLE_GAP_EVT_DISCONNECTED:
        err_code = bsp_indication_set(BSP_INDICATE_IDLE);
        APP_ERROR_CHECK(err_code);

        err_code = bsp_indication_set(BSP_INDICATE_ALERT_OFF);
        APP_ERROR_CHECK(err_code);
        break;
			case BLE_GAP_EVT_ADV_REPORT: 
			{
											// Advertising data received
					const ble_gap_evt_adv_report_t *p_adv = &p_ble_evt->evt.gap_evt.params.adv_report;
			
					
						
						
	// create node for every new ble address

	  new_node=(struct node *)malloc(sizeof(struct node));   ---> this will stop the bluetooth (I think its get stuck to initialize heap memory)

       }
      break;

Any help will be appreciate.

Hi

Simply ignore every things just i call malloc to create dynamic memory in main() loop. The BLE advertising get stop.

Its very difficult to me find out proper solution what's actually problem?

I think when malloc goes to create dynamic memory its get stuck and BLE adv. get stop. After Implementing malloc I can't debug my program.

See bellow code this will give more idea,

Please help any one whats wrong?

Since your app is working on 32 RAM device (nrf51 AC), but not on 16k (nrf51 AA) it could be a problem with your RAM configuraion. Since you are using makefile, check your linker script under MEMORY section -> RAM: The sum of ORIGIN and LENGTH should equal 0x20004000.

EDIT: For Keil: Go to target options, Read/Write Memory Areas: Start and Size of IRAM1 fields should equal 0x20004000
