### <iclass="fa fa-caret-right"></i> Change menu title
Although the default menu title is **AutoConnect**, you can change the title by setting [*AutoConnectConfig::title*](apiconfig.md#title). To set the menu title properly, you must set before calling [*AutoConnect::begin*](api.md#begin).
```cpp hl_lines="6 7"

Executing the above sketch will rewrite the menu title for the **FSBrowser** as the below.
You can change the label text for each menu item but cannot change them at run time. There are two ways to change the label text, both of which require coding the label literal.
1. Overwrite the label literal of library source code directly.
You can change the label of the AutoConnect menu item by rewriting the default label literal in [AutoConnectLabels.h](https://github.com/Hieromon/AutoConnect/blob/master/src/AutoConnectLabels.h) macros. However, changing menu items literal influences all the sketch's build scenes.

!!! note "**buld_flags** with PlatformIO will no effect"
The mistake that many people make is to use PlatformIO's build_flags to try to redefine any literal at compile time.<br>
The AutoConnect library statically contains the label literals which are embedded as binary data when compiling the library code. The label literals will not change without compiling the library source.<br>
And PlatformIO is a build system. Library sources will not be compiled unless AutoConnectLabels.h is updated.
You can change the label of the AutoConnect menu item by rewriting the default label letter in [AutoConnectLabels.h](https://github.com/Hieromon/AutoConnect/blob/master/src/AutoConnectLabels.h) macros. However, changing menu items letter influences all the sketch's build scenes.
2. Change the label literals for each Arduino project
```cpp
#define AUTOCONNECT_MENULABEL_CONFIGNEW "Configure new AP"
Another way to change the label literal is to provide a header file that defines the label literals, as mentioned in [Appendix](changelabel.md#change-the-items-label-text). You can also use this method to display label text and fixed text in the local language on the AutoConnect page.

### <iclass="fa fa-caret-right"></i> Connects depending on the WiFi signal strength
When the ESP module found the multiple available access points (ie. AutoConnect has connected in the past), the default behavior AutoConnect will attempt to connect to the least recent one. However, If the ESP module can operate properly with any access point, it is advantageous to establish a connection with the best one of the reception sensitivity.
The [*AutoConnectConfig::principle*](apiconfig.md#principle) parameter has the connection disposition, and specifying **AC_PRINCIPLE_RSSI** will attempt to connect to one of the highest RSSI value among multiple available access points. Also You can expect stable WiFi connection by specifying the lower limit of signal strength using [*AutoConnectConfig::minRSSI*](apiconfig.md#minrssi).
Combining these two parameters allows you to filter the destination AP when multiple available access points are found.
[*AutoConnectConfig::principle*](apiconfig.md#principle) affects the behavior of both 1st-WiFi.begin and [**autoReconnect**](advancedusage.md#automatic-reconnect). If you specify **AC_PRINCIPLE_RECENT** for the [**principle**](apiconfig.md#principle), it will try according to the conventional connection rules, but if you specify **AC_PRINCIPLE_RSSI**, it will try to connect to the access point that is sending the strongest WiFi signal at that time instead of the last accessed AP. Also, the static IPs will be restored from a saved credential instead of AutoConnectConfig. (The values specified by AutoConnectConfig is ignored)

### <iclass="fa fa-caret-right"></i>Move the saving area of EEPROM for the credentials
### <iclass="fa fa-caret-right"></i>On-demand start the captive portal
By default, the credentials saving area is occupied from the beginning of EEPROM area. [ESP8266 Arduino core document](http://arduino-esp8266.readthedocs.io/en/latest/filesystem.html?highlight=eeprom#flash-layout) says that:
The [default behavior of AutoConnect::begin](lsbegin.md) gives priority to connect to the least recently established access point. In general, We expect this behavior in most situations, but will intentionally launch the captive portal on some occasion.
Here section describes how to launch on demand the captive portal, and suggests two templates that you can use to implement it.
> The following diagram illustrates flash layout used in Arduino environment:
1. Offline for usual operation, connect to WiFi with an external switch
> Sketch OTA update File system EEPROM WiFi config (SDK)
> ```
You can use this template if the ESP module does not connect to WiFi at an ordinal situation and need to establish by a manual trigger. In this case, it is desirable that AutoConnect not start until an external switch fires. This behavior is similar to the [WiFiManager's startConfigPortal](https://github.com/tzapu/WiFiManager#on-demand-configuration-portal) function.
[*AutoConnectConfig::immediateStart*](apiconfig.md#immediatestart) is an option to launch the portal by the SoftAP immediately without attempting 1st-WiFi.begin. Also, by setting the [*AutoConnectConfig::autoRise*](apiconfig.md#autorise) option to false, it is possible to suppress unintended automatic pop-ups of the portal screen when connecting to an ESP module SSID.
To implement this, execute AutoConnect::config within the **setup()** function as usual, and handle AutoConnect::begin inside the **loop()** function.
and
```cpp hl_lines="9"
#define TRIGGER_PIN 5 // Trigger switch should be LOW active.

AutoConnect Portal;
AutoConnectConfig Config;
Also, in ESP32 arduino core 1.0.2 earlier, the placement of the EEPROM area of ESP32 is described in the [partition table](https://github.com/espressif/arduino-esp32/blob/master/tools/partitions/default.csv). So in the default state, the credential storage area used by AutoConnect conflicts with data owned by the user sketch. It will be destroyed together saved data in EEPROM by user sketch and AutoConnect each other. But you can move the storage area to avoid this.
void setup() {
pinMode(5, INPUT_PULLUP);
Config.immediateStart = true;
// Config.autoRise = false; // If you don't need to automatically pop-up the portal when connected to the ESP module's SSID.
Portal.config(Config);
}
The [**boundaryOffset**](apiconfig.md#boundaryoffset) in [AutoConnectConfig](apiconfig.md) specifies the start offset of the credentials storage area. The default value is 0.
void loop() {
if (digitalRead(TRIGGER_PIN) == LOW) {

}
!!! info "The boundaryOffset ignored with AutoConnect v1.0.0 later on ESP32 arduino core 1.0.3 later"
For ESP32 arduino core 1.0.3 and later, AutoConnect will store credentials to Preferences in the nvs. Since it is defined as the namespace dedicated to AutoConnect and separated from the area used for user sketches. Therefore, the [boundaryOffset](apiconfig.md#boundaryoffset) is ignored with the combination of AutoConnect v1.0.0 or later and the arduino-esp32 1.0.3 or later.

### <iclass="fa fa-caret-right"></i> On-demand start the captive portal
// Main process of your sketch
If you do not usually connect to WiFi and need to establish a WiFi connection if necessary, you can combine the [**autoRise**](apiconfig.md#autorise) option with the [**immediateStart**](apiconfig.md#immediatestart) option to achieve on-demand connection. This behavior is similar to the [WiFiManager's startConfigPortal](https://github.com/tzapu/WiFiManager#on-demand-configuration-portal) function. In order to do this, you usually configure only with AutoConnectConfig in *setup()* and [*AutoConnect::begin*](api.md#begin) handles in *loop()*.
Portal.handleClient(); // If WiFi is not connected, handleClient will do nothing.
}
```
```cpp hl_lines="5 6"
AutoConnect Portal;
AutoConnectConfig Config;
!!! note "It will not be automatic reconnect"
The above example does not connect to WiFi until TRIGGER\_PIN goes LOW. When TRIGGER\_PIN goes LOW, the captive portal starts and you can connect to WiFi. Even if you reset the module, it will not automatically reconnect.
void setup() {
Config.autoRise = false;
Config.immediateStart = true;
Portal.config(Config);
}
2. Register new access points on demand
void loop() {
if (digitalRead(TRIGGER_PIN) == LOW) {
while (digitalRead(TRIGGER_PIN) == LOW)
yield();
Portal.begin();
}
Portal.handleClient();
}
```
The above example does not connect to WiFi until TRIGGER\_PIN goes LOW. When TRIGGER\_PIN goes LOW, the captive portal starts and you can connect to WiFi. Even if you reset the module, it will not automatically reconnect.
The following template is useful for controlling the registration of unknown access points. In this case, the ESP module establishes a WiFi connection using WiFi.begin natively without relying on AutoConnect.
Known access point credentials are saved by AutoConnect, to the ESP module can use the saved credentials to handle WiFi.begin natively. This means that you can explicitly register available access points when needed, and the ESP module will not use unknown access points under normal situations.
```cpp
AutoConnect* portal = nullptr;
bool detectSwitch() {
/*
Returns true if an external switch to configure is active.
if (connectWiFi(config.ssid, config.password, 30000))
break;
}
if (WiFi.status() != WL_CONNECTED) {
// Here, do something when WiFi cannot reach.
}
}
void loop() {
if (detectSwitch()) {

config.immediateStart= true;
if (!portal) {
portal = new AutoConnect;
}
portal->config(config);
if (portal->begin()) {
portal->end();
delete portal;
portal = nullptr;
}
}
// Here, ordinally sketch logic.

Appropriately specifying the WiFi channel to use for ESP8266 and ESP32 is essential for a stable connection with the access point. AutoConnect remembers the WiFi channel with a credential of the access point once connected and reuses it.
The default channel when a captive portal starts and AutoConnect itself becomes an access point is the [*AutoConnectConfig::channel*](apiconfig.md#channel) member. If this channel is different from the channel of the access point you will attempt to connect, WiFi.begin may fail. The cause is that the ESP module shares the same channel in AP mode and STA mode. If the connection attempt is not stable, specifying a proper channel using AutoConnectConfig::channel may result in a stable connection.
