Sleep in connected mode

[Reshmi Marimganti]

Question:

From ble device I have to send some data or character to mobile in connected mode. After sending that data the device is not going to sleep mode while connected condition.

if I use sleep mode function, the device gets disconnected with the mobile. so how can I make the device go to sleep mode while in connected mode.

What function I have to use?

I have added the sleep code inside BLE_GAP_EVENT_CONNECTED

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_advertising_mode = BLE_NO_ADV;   
        m_conn_handle      = p_ble_evt->evt.gap_evt.conn_handle;    
			
	nrf_delay_ms(2000);   
		      
uint32_t err_code = bsp_indication_set(BSP_INDICATE_IDLE);
APP_ERROR_CHECK(err_code);

// Prepare wakeup buttons.    
err_code = bsp_btn_ble_sleep_mode_prepare();    
APP_ERROR_CHECK(err_code);      

// Go to system-off mode (this function will not return; wakeup will cause a reset).    
err_code = sd_power_system_off();    
APP_ERROR_CHECK(err_code);   
	       
 break;
