Where are the print statements for the RTT output shown in BLE Services tutorial

[Renix]

The RTT output screenshot shows messages for BLE_GAP_EVT_CONNECTED, BLE_GAP_EVT_DISCONNECTED, BLE_GAP_EVT_CONN_PARAM_UPDATE

I would guess it's something like this:

case BLE_GAP_EVT_CONNECTED:

	SEGGER_RTT_WriteString(0, "GAP Evt: BLE_GAP_EVT_CONNECTED\n");
	SEGGER_RTT_printf(0, "\tConn handle: 0x%02x\n", p_ble_evt->evt.gap_evt.conn_handle);
	SEGGER_RTT_printf(0, "\tMIN_CONN_INTERVAL: %d\n", p_ble_evt->evt.gap_evt.params.connected.conn_params.min_conn_interval);
	SEGGER_RTT_printf(0, "\tCONN_SUP_TIMEOUT: %d\n", p_ble_evt->evt.gap_evt.params.connected.conn_params.conn_sup_timeout);
	SEGGER_RTT_printf(0, "\tSLAVE_LATENCY: %d\n", p_ble_evt->evt.gap_evt.params.connected.conn_params.slave_latency);
	break; // BLE_GAP_EVT_CONNECTED

case BLE_GAP_EVT_DISCONNECTED:

	SEGGER_RTT_WriteString(0, "GAP Evt: BLE_GAP_EVT_DISCONNECTED\n");
	SEGGER_RTT_printf(0, "\tConn handle: 0x%02x\n", p_ble_evt->evt.gap_evt.conn_handle);
	SEGGER_RTT_printf(0, "\t%d\n", p_ble_evt->evt.gap_evt.params.disconnected.reason);
   
	break; // BLE_GAP_EVT_DISCONNECTED

case  BLE_GAP_EVT_CONN_PARAM_UPDATE:

	SEGGER_RTT_WriteString(0, "GAP Evt: BLE_GAP_EVT_CONN_PARAM_UPDATE\n");
	SEGGER_RTT_printf(0, "\tConn handle: 0x%02x\n", p_ble_evt->evt.gap_evt.conn_handle);
	SEGGER_RTT_printf(0, "\tMIN_CONN_INTERVAL: %d\n", p_ble_evt->evt.gap_evt.params.conn_param_update.conn_params.min_conn_interval);
	SEGGER_RTT_printf(0, "\tCONN_SUP_TIMEOUT: %d\n", p_ble_evt->evt.gap_evt.params.conn_param_update.conn_params.conn_sup_timeout);
	SEGGER_RTT_printf(0, "\tSLAVE_LATENCY: %d\n", p_ble_evt->evt.gap_evt.params.conn_param_update.conn_params.slave_latency);

	break; // BLE_GAP_EVT_CONN_PARAM_UPDATE

Note that this will only print the status number of the disconnect reason. You can compare it against this list.

Sorry, I did not see that file. Yes, you should be able to call print_evt() in on_ble_evt() handler if you include msgs.h in the application.
