WiFiManager_NINA_Lite (Light Weight Credentials / WiFi Manager for WiFiNINA modules/shields)

New recent features:

MultiWiFi feature for configuring/auto(re)connecting WiFiNINA shields to the available MultiWiFi APs at runtime.
DoubleDetectDetector feature to force Config Portal when double reset is detected within predetermined time, default 10s.
Configurable Config Portal Title to be either BoardName or default undistinguishable names.
Examples are redesigned to separate Credentials / Defines / Dynamic Params / Code so that you can change Credentials / Dynamic Params quickly for each device.

New Release v1.0.5

Modify LOAD_DEFAULT_CONFIG_DATA logic.
Enhance MultiWiFi connection logic.
Add Adafruit MQTT examples.

Major Release v1.0.4

Configurable Config Portal Title to be either HostName, BoardName or default undistinguishable names.
Optional default Credentials as well as Dynamic parameters to be optionally autoloaded into Config Portal to use or change instead of manually input.
DoubleDetectDetector feature to force Config Portal when double reset is detected within predetermined time, default 10s.
Examples are redesigned to separate Credentials / Defines / Dynamic Params / Code so that you can change Credentials / Dynamic Params quickly for each device.
Add Board Name

Thanks to thorathome in GitHub to test, suggest and encourage to add those new features in Blynk_WM, such as Default Credentials/Dynamic Params, Configurable Config Portal Title, DRD. Now those features are speading fast into libraries having similar functionalities.

Major Release v1.0.3

Multiple WiFi Credentials (SSID, Password) and system will autoconnect to the available WiFi AP. It will then autoreconnect to the remaining WiFi AP if the current connection is lost.
Add support to nRF52 boards, such as AdaFruit Feather nRF52832, nRF52840 Express, BlueFruit Sense, Itsy-Bitsy nRF52840 Express, Metro nRF52840 Express, NINA_B302_ublox, NINA_B112_ublox, etc.
WiFi Password max length is 63, according to WPA2 standard
Permit to input special chars such as % and # into data fields.
Add option to have built-in, yet configurable RFC-952-conformed DHCP hostname.
Fix bug

New in v1.0.2

Fix bug
Add support to SAM51 (Itsy-Bitsy M4, Metro M4, Grand Central M4, Feather M4 Express, etc.).

New in v1.0.1

Use new WiFiNINA_Generic library to provide support to many more boards (Teensy, AVR Mega, SAM DUE, SAMD51, STM32, etc.) running WiFiNINA. The original WiFiNINA library only supports Nano-33 IoT, Arduino MKR WiFi 1010, Arduino MKR VIDOR 4000 and Arduino UNO WiFi Rev.2.
Use new FlashStorage_SAMD library to provide EEPROM/FlashStorage support to SAMD51 boards (Itsy-Bitsy M4, etc).

New in v1.0.0

New powerful-yet-simple-to-use feature to enable adding dynamic custom parameters from sketch and input using the same Config Portal. Config Portal will be auto-adjusted to match the number of dynamic parameters.
Dynamic custom parameters to be saved automatically in EEPROM, SAMD EEPROM-emulated FlashStorage or SAM DUE DueFlashStorage.

Features

This library is a Light Weight Credentials / WiFi Manager for WiFiNINA modules/shields, specially designed to support Teensy, SAM DUE, SAMD21 (Nano-33 IoT, Itsy-Bitsy M0, etc), SAMD51 (Itsy-Bitsy M4, Metro M4, Grand Central M4, Feather M4 Express, etc.), STM32F (F1, F2, F3, F4, F7, Nucleo-144, etc.), nRF52 (Adafruit NRF52840_FEATHER, NRF52832_FEATHER, NRF52840_FEATHER_SENSE, NRF52840_ITSYBITSY, NRF52840_CIRCUITPLAY, NRF52840_CLUE, NRF52840_METRO, NRF52840_PCA10056, PARTICLE_XENON, NINA_B302_ublox, NINA_B112_ublox, etc.), etc. boards running WiFiNINA modules/shields. with smaller memory (64+K bytes)

The AVR-family boards (UNO, Nano, etc.) are not supported as they don't have enough memory to run Config Portal WebServer.

This is a Credentials / WiFi Connection Manager, permitting the addition of custom parameters to be configured in Config Portal. The parameters then will be saved automatically, without the complicated callback functions to handle data saving / retrieving.

You can also specify DHCP HostName, static AP and STA IP. Use much less memory compared to full-fledge WiFiManager. Config Portal will be auto-adjusted to match the number of dynamic custom parameters. Credentials are saved in EEPROM, FlashStorage or DueFlashStorage.

If you have used the full-fledge WiFiManager such as :

and have to write complicated callback functions to save custom parameters in SPIFFS, you'd appreciate the simplicity of this Light-Weight Credentials / WiFiManager.

The web configuration portal, served from the WiFiNINA modules/shields is operating as an access point (AP) with configurable static IP address or use default IP Address of 192.168.4.1

How It Works

The SAMD_WiFiNINA example shows how it works and should be used as the basis for a sketch that uses this library.
The concept of SAMD_WiFiNINA is that a new WiFiNINA module/shield will start a WiFi configuration portal when powered up, but has no valid stored Credentials or can't connect to WiFi APs after a pre-determined time.
There are 6 more custom parameters added in the sketch which you can use in your program later. In the example, they are: 2 sets of Blynk Servers and Tokens, Blynk Port and MQTT Server.
Using any WiFi enabled device with a browser (computer, phone, tablet) connect to the newly created AP and type in the configurable AP IP address (default 192.168.4.1). The Config Portal AP channel (default 10) is also configurable to avoid conflict with other APs.
The Config Portal is auto-adjusted to fix the 4 static parameters (WiFi SSIDs/PWDs) as well as 6 more dynamic custom parameters.
After the custom data entered, and Save button pressed, the configuration data will be saved in host's non-volatile memory, then the board reboots.
If there is valid stored Credentials, it'll go directly to connect to one of the MultiWiFi APs without starting / using the Config Portal.
WiFiNINA module/shield will try to connect. If successful, the dynamic DHCP and/or configured static IP address will be displayed in the configuration portal.
The WiFiNINA module/shield WiFi Config Portal network and Web Server will shutdown to return control to the sketch code.
In the operation, if the current WiFi connection is lost because of any reason, the system will auto(Re)connect to the remaining WiFi AP.
If system can't connect to any of the 2 WiFi APs, the Config Portal will start, after some pre-determined time, to permit user to update the Credentials.

Quick Start

The best and easiest way is to use Arduino Library Manager. Search for WiFiManager_NINA_Lite, then select / install the latest version. You can also use this link for more detailed instructions.

Manual Install

Another way to install is to:

Navigate to WiFiManager_NINA_Lite page.
Download the latest release WiFiManager_NINA_Lite-master.zip.
Extract the zip file to WiFiManager_NINA_Lite-master directory
Copy whole WiFiManager_NINA_Lite-master/src folder to Arduino libraries' directory such as ~/Arduino/libraries/.

Using

Include in your sketch

// Must be before #include <WiFiManager_NINA_Lite_SAMD.h>
// Start location in EEPROM to store config data. Default 0
// Config data Siz, not including your custom data, currently is 84 bytes)
#define EEPROM_START      0

#include <WiFiManager_NINA_Lite_SAMD.h>

WiFiManager_NINA_Lite* WiFiManager_NINA;

To add custom parameters, just add

#define USE_DYNAMIC_PARAMETERS      true

#else

MenuItem myMenuItems [] = {};

uint16_t NUM_MENU_ITEMS = 0;

#endif    //USE_DYNAMIC_PARAMETERS

If you don't need to add dynamic parameters, use the following in sketch

#define USE_DYNAMIC_PARAMETERS      false

When you want to open a config portal, just add

WiFiManager_NINA = new WiFiManager_NINA_Lite();
WiFiManager_NINA->begin();

To not use default AP WiFi Channel 10 to avoid conflict with other WiFi APs, call

WiFiManager_NINA->setConfigPortalChannel(newChannel);

To use different static AP IP (not use default 192.168.4.1), call

WiFiManager_NINA->setConfigPortalIP(IPAddress(xxx,xxx,xxx,xxx));

To set custom DHCP HostName, cal

  // Set customized DHCP HostName
  WiFiManager_NINA->begin("SAMD-WiFiNINA-ABCDEF");

or just use the default Hostname, for example "SAMD-WiFiNINA-XXXXXX" for SAMD

  //Or use default Hostname "SAMD-WiFiNINA-XXXXXX"
  //WiFiManager_NINA->begin();

While in AP mode, connect to it using its SSID (WIFININA_XXXXXX) / Password ("MyWIFININA_XXXXXX"), then open a browser to the Portal AP IP, default 192.168.4.1, configure wifi then click Save. The Credentials / WiFi connection information will be saved in non-volatile memory. It will then autoconnect.

Once Credentials / WiFi network information is saved in the host non-volatile memory, it will try to autoconnect to WiFi every time it is started, without requiring any function calls in the sketch.

Also see examples:

So, how it works?

In Configuration Portal Mode, it starts an AP called WIFININA_XXXXXX. Connect to it using the configurable password you can define in the code. For example, MyWIFININA_XXXXXX (see examples):

After you connected, please, go to http://192.168.4.1 or newly configured AP IP, you'll see this Main page:

Enter your credentials,

then click Save.

The WiFi Credentials will be saved and the board connect to the selected WiFi AP.

If you're already connected to a listed WiFi AP and don't want to change anything, just select Exit from the Main page to reboot the board and connect to the previously-stored AP. The WiFi Credentials are still intact.

Important Notes

Now you can use special chars such as ~, !, @, #, $, %, ^, &, _, -, space,etc. thanks to brondolin to provide the amazing fix in Blynk_WM to permit input special chars such as % and # into data fields. See Issue 3.
The SSIDs, Passwords must be input (or to make them different from blank). Otherwise, the Config Portal will re-open until those fields have been changed. If you don't need any field, just input anything or use duplicated data from similar field.
WiFi password max length now is 63 chars according to WPA2 standard.

How to use default Credentials and have them pre-loaded onto Config Portal

See this example and modify as necessary

To always load Default Credentials and override Config Portal data

// Used mostly for development and debugging. FORCES default values to be loaded each run.
// Config Portal data input will be ignored and overridden by DEFAULT_CONFIG_DATA
bool LOAD_DEFAULT_CONFIG_DATA = true;

To load Default Credentials when there is no valid Credentials. Config Portal data input will be override DEFAULT_CONFIG_DATA

// Used mostly once debugged. Assumes good data already saved in device.
// Config Portal data input will be override DEFAULT_CONFIG_DATA
bool LOAD_DEFAULT_CONFIG_DATA = false;

Please be noted that the following reserved names are already used in library:

"id"    for WiFi SSID
"pw"    for WiFi PW
"id1"   for WiFi1 SSID
"pw1"   for WiFi1 PW
"nm"    for Board Name

Debug

Debug is enabled by default on Serial. To disable, add at the beginning of sketch

/* Comment this out to disable prints and save space */
#define DEBUG_WIFI_WEBSERVER_PORT Serial

#define WIFININA_DEBUG_OUTPUT     Serial

#define WIFININA_DEBUG            true

#define DRD_GENERIC_DEBUG         true

Troubleshooting

If you get compilation errors, more often than not, you may need to install a newer version of the board's core, WiFiNINA module/shield or this library version.

Sometimes, the library will only work if you update the WiFiNINA module/shield core to the newer or older version because some function compatibility.

TO DO

Support more boards

DONE

Adding dynamic custom parameters
Add MultiWiFi and Auto(Re)Connect feature
Add support to SAMD21, SAMD51, nRF52, etc.
Many more to list ( DHCP Hostname, WPA2 password length, special chars, etc.)
Add DRD
Add default Credentials
Add Dynamic parameters
Add Configurable Config Portal Title
Spilt each example into several manageable files.

New Release v1.0.5

Modify LOAD_DEFAULT_CONFIG_DATA logic.
Enhance MultiWiFi connection logic.
Add Adafruit MQTT examples.

Major Release v1.0.4

Configurable Config Portal Title to be either HostName, BoardName or default undistinguishable names.
Optional default Credentials as well as Dynamic parameters to be optionally autoloaded into Config Portal to use or change instead of manually input.
DoubleDetectDetector feature to force Config Portal when double reset is detected within predetermined time, default 10s.
Examples are redesigned to separate Credentials / Defines / Dynamic Params / Code so that you can change Credentials / Dynamic Params quickly for each device.
Add Board Name

Major Release v1.0.3

Multiple WiFi Credentials (SSID, Password) and system will autoconnect to the available WiFi AP. It will then autoreconnect to the remaining WiFi AP if the current connection is lost.
Add support to nRF52 boards, such as AdaFruit Feather nRF52832, nRF52840 Express, BlueFruit Sense, Itsy-Bitsy nRF52840 Express, Metro nRF52840 Express, NINA_B302_ublox, NINA_B112_ublox, etc.
WiFi Password max length is 63, according to WPA2 standard
Permit to input special chars such as % and # into data fields.
Add option to have built-in, yet configurable RFC-952-conformed DHCP hostname.
Fix bug

New in v1.0.2

Fix bug
Add support to SAM51 (Itsy-Bitsy M4, Metro M4, Grand Central M4, Feather M4 Express, etc.).

New in v1.0.1

Use new WiFiNINA_Generic library to provide support to many more boards (Teensy, AVR Mega, SAM DUE, SAMD51, STM32, etc.) running WiFiNINA. The original WiFiNINA library only supports Nano-33 IoT, Arduino MKR WiFi 1010, Arduino MKR VIDOR 4000 and Arduino UNO WiFi Rev.2.
Use new FlashStorage_SAMD library to provide EEPROM/FlashStorage support to SAMD51 boards (Itsy-Bitsy M4, etc).

New in v1.0.0

New powerful-yet-simple-to-use feature to enable adding dynamic custom parameters from sketch and input using the same Config Portal. Config Portal will be auto-adjusted to match the number of dynamic parameters.
Dynamic custom parameters to be saved automatically in EEPROM, SAMD EEPROM-emulated FlashStorage or SAM DUE DueFlashStorage.
This is a Light-Weight Credentials / WiFi Connection Manager with fallback web configuration portal. Completely new to support Teensy, SAM DUE, SAMD, STM32, etc. boards running WiFiNINA modules/shields. with small memory (64+K bytes)
Config Portal AP SSID and Password will use 4 bytes of hardware unique macAddress, only for Teensy.

Contributions and thanks

Thanks to Darvesh7 to report When Saved Network is unavailable or credential changed bug leading to the major release v1.0.3
Thanks to thorathome in GitHub to test, suggest and encourage to add those new features in Blynk_WM, such as Default Credentials/Dynamic Params, Configurable Config Portal Title, DRD. Now those features are speading fast into libraries having similar functionalities.
Thanks to great work of Miguel Alexandre Wisintainer for initiating, inspriring, working with, developing, debugging and testing. Without that, support to nRF52, especially U-Box B302, B112 running as nRF52840/nRF52832, has never been started and finished. See u-blox nina b
