RSSI Start problem NRF_ERROR_SOFTDEVICE_NOT_ENABLED

[Yoojin.Jang]

Hello. I want RSSI check. so added source code as below.

test_rssi_start = sd_ble_gap_rssi_start(m_conn_handle,BLE_GAP_RSSI_THRESHOLD_INVALID,0x00); if(test_rssi_start==NRF_SUCCESS){ app_uart_put(0x53); }

but, rssi_start NRF_SUCCESS is fail. error occur NRF_ERROR_SOFTDEVICE_NOT_ENABLED. Please solve the above problem and give me rssi example. thank you.

thank you for your support. when Central and Peripheral is connect, start sd_ble_gap_rssi_start in the ble_db_discovery_on_ble_evt function. my source code as below. How to enable softdevice?

switch (p_ble_evt->header.evt_id)

{
    case BLE_GAP_EVT_CONNECTED:
				p_db_discovery->conn_handle = p_ble_evt->evt.gap_evt.conn_handle;
				 test_rssi_start = sd_ble_gap_rssi_start(m_conn_handle,BLE_GAP_RSSI_THRESHOLD_INVALID,0x00);
			if(test_rssi_start==NRF_SUCCESS){
				app_uart_put(0x53);
			}				
        break;
    
    case BLE_GAP_EVT_DISCONNECTED:
        memset(p_db_discovery, 0, sizeof(ble_db_discovery_t));
        p_db_discovery->conn_handle = BLE_CONN_HANDLE_INVALID;
			sd_ble_gap_rssi_stop(m_conn_handle);
			app_uart_put(0x45);
        break;
