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?

After adding this line head = (struct node *)malloc(sizeof(struct node)); I can't debug.

Which chip are you tested to work malloc?

I also test nRF51822AC, nRF52 malloc work fine with ble example code. But problem with nRF51822AA chip which not create dynamic memory in ble example code. Its work fine without ble example code like blinky example.

Any suggestion regrading, How to create Dynamic memory with malloc in nRF51822AA chip?
