Important Notes for Portenta_H7

LittleFS

The LittleFS of the new Portenta_H7 board currently tested OK with only maximum 8 files. The files, from 9 and up, somehow strangely can't be written and / or read. This is possibly a bug in the ArduinoCore-mbed mbed_portenta core. The same behaviour is observed from core v2.0.0 up to v2.5.2.

If LittleFS size is reduced to 1024KB, test is OK with only maximum 4 files.

Beware and keep checking for updates.

WiFi.status() bug

The current mbed_portenta core v2.6.1 has bug that once WiFi is connected, WiFi.status() always reports WL_CONNECTED even if WiFi is lost.

The current workaround for this WiFi.status() bug is to use it with WiFi.RSSI(), such as

bool WiFiConnected()
{
  return ( (WiFi.status() == WL_CONNECTED) && (WiFi.RSSI() != 0) );
}

This not-100%-perfect workaround is working only whenever the WiFi is totally powered down (RSSI == 0), but still better than nothing.

Check

WiFi.begin() bug

The current mbed_portenta core v2.6.1 has bug that once WiFi is connected and lost, WiFi.begin() can't never reconnect even if WiFi is restored.

The current fix for this bug is to use WiFi.end() before WiFi.begin(), such as

// Must have to reconnect after WiFi lost
WiFi.end();
  
// Now WiFi.begin() can reconnect to WiFi after lost and restored  
status = WiFi.begin(ssid, pass);

Why do we need this WiFiManager_Portenta_H7_Lite library

Features

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

  1. Tzapu WiFiManager
  2. Ken Taylor WiFiManager
  3. Khoi Hoang ESP_WiFiManager

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

This library is a Light Weight Credentials / WiFi Manager for Portenta_H7 built-in WiFi (Murata) modules/shields, specially designed to support Portenta_H7 running on M7 core.

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 LittleFS, shared with DoubleResetDetector_Generic library.

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

New recent features:

  • MultiWiFi feature for configuring/auto(re)connecting Portenta WiFi shields to the available MultiWiFi APs at runtime.
  • DoubleDetectDetector feature to force Config Portal when double reset is detected within predetermined time, default 10s.
  • 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.
  • Optional default Credentials as well as Dynamic parameters to be optionally autoloaded into Config Portal to use or change instead of manually input.
  • Dynamic custom parameters to be saved automatically in non-volatile LittleeFS memory.
  • Configurable Config Portal Title to be either BoardName or default undistinguishable names.
  • Examples are designed to separate Credentials / Defines / Dynamic Params / Code so that you can change Credentials / Dynamic Params quickly for each device.
  • Control Config Portal from software or Virtual Switches
  • To permit autoreset after configurable timeout if DRD/MRD or non-persistent forced-CP
  • Use new Portenta_H7 LittleFS features
  • Scan WiFi networks for selection in Configuration Portal

WiFiMulti_Generic library usage

  1. Install VS Code
  2. Install PlatformIO
  3. Install WiFiManager_Portenta_H7_Lite library by using Library Manager. Search for WiFiManager_Portenta_H7_Lite in Platform.io Author's Libraries
  4. Use included platformio.ini file from examples to ensure that all dependent libraries will installed automatically. Please visit documentation for the other options and examples at Project Configuration File

Packages' Patches

1. For Portenta_H7 boards using Arduino IDE in Linux

To be able to upload firmware to Portenta_H7 using Arduino IDE in Linux (Ubuntu, etc.), you have to copy the file portenta_post_install.sh into mbed_portenta directory (~/.arduino15/packages/arduino/hardware/mbed_portenta/3.4.1/portenta_post_install.sh).

Then run the following command using sudo

$ cd ~/.arduino15/packages/arduino/hardware/mbed_portenta/3.4.1
$ chmod 755 portenta_post_install.sh
$ sudo ./portenta_post_install.sh

This will create the file /etc/udev/rules.d/49-portenta_h7.rules as follows:

# Portenta H7 bootloader mode UDEV rules

SUBSYSTEMS=="usb", ATTRS{idVendor}=="2341", ATTRS{idProduct}=="035b", GROUP="plugdev", MODE="0666"

Supposing the ArduinoCore-mbed core version is 3.4.1. Now only one file must be copied into the directory:

  • ~/.arduino15/packages/arduino/hardware/mbed_portenta/3.4.1/portenta_post_install.sh

Whenever a new version is installed, remember to copy this files into the new version directory. For example, new version is x.yy.zz

This file must be copied into the directory:

  • ~/.arduino15/packages/arduino/hardware/mbed_portenta/x.yy.zz/portenta_post_install.sh

How It Works

  • The Portenta_H7_WiFi example shows how it works and should be used as the basis for a sketch that uses this library.
  • The concept of Portenta_H7_WiFi is that a new WiFi 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.
  • Generic WiFi 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 Generic WiFi 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.

How to use

1. Basic usage

  • Include in your sketch
#include <WiFiManager_Portenta_H7_Lite.h>

WiFiManager_Portenta_H7_Lite* WiFiManager_Portenta_H7;

2. Add custom parameters

  • To add custom parameters, just add
#include "defines.h"

// USE_DYNAMIC_PARAMETERS defined in defines.h

/////////////// Start dynamic Credentials ///////////////

//Defined in <WiFiManager_Portenta_H7_Lite.h>
/**************************************

#if USE_DYNAMIC_PARAMETERS

#define MAX_BLYNK_SERVER_LEN      34
#define MAX_BLYNK_TOKEN_LEN       34

char Blynk_Server1 [MAX_BLYNK_SERVER_LEN + 1]  = "account.duckdns.org";
char Blynk_Token1  [MAX_BLYNK_TOKEN_LEN + 1]   = "token1";

};

uint16_t NUM_MENU_ITEMS = sizeof(myMenuItems) / sizeof(MenuItem);  //MenuItemSize;

#else

MenuItem myMenuItems [] = {};

uint16_t NUM_MENU_ITEMS = 0;

#endif    //USE_DYNAMIC_PARAMETERS

3. Not using custom parameters

  • If you don't need to add dynamic parameters, use the following in sketch
#define USE_DYNAMIC_PARAMETERS      false

4. To open Config Portal

  • When you want to open a config portal, just add
WiFiManager_Portenta_H7 = new WiFiManager_Portenta_H7_Lite();
WiFiManager_Portenta_H7->begin();

5. To use different AP WiFi Channel

  • To not use default AP WiFi Channel 10 to avoid conflict with other WiFi APs :
WiFiManager_Portenta_H7->setConfigPortalChannel(newChannel);
  • To use random AP WiFi Channel to avoid conflict with other WiFi APs :
WiFiManager_Portenta_H7->setConfigPortalChannel(0);

6. To use different static AP IP from default

  • To use different static AP IP (not use default 192.168.4.1), call
WiFiManager_Portenta_H7->setConfigPortalIP(IPAddress(xxx,xxx,xxx,xxx));

7. To use custom DHCP HostName

  • To set custom DHCP HostName :
// Set customized DHCP HostName
WiFiManager_Portenta_H7->begin("SAMD_ABCDEF");

or just use the default Hostname, for example "SAMD_XXXXXX" for SAMD

//Or use default Hostname "WIFI_GENERIC_XXXXXX"
//WiFiManager_Portenta_H7->begin();

8. To use custom HTML Style

const char NewCustomsStyle[] /*PROGMEM*/ = "<style>div,input{padding:5px;font-size:1em;}input{width:95%;}body{text-align: center;}\
button{background-color:blue;color:white;line-height:2.4rem;font-size:1.2rem;width:100%;}fieldset{border-radius:0.3rem;margin:0px;}</style>";

...

WiFiManager_Portenta_H7->setCustomsStyle(NewCustomsStyle);

9. To use custom Head Elements

WiFiManager_Portenta_H7->setCustomsHeadElement("<style>html{filter: invert(10%);}</style>");

10. To use CORS Header

WiFiManager_Portenta_H7->setCORSHeader("Your Access-Control-Allow-Origin");

While in AP mode, connect to it using its SSID (WIFI_GENERIC_XXXXXX) / Password ("MyWIFI_GENERIC_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.

11. To use and input only one set of WiFi SSID and PWD

11.1 If you need to use and input only one set of WiFi SSID/PWD

// Permit input only one set of WiFi SSID/PWD. The other can be "NULL or "blank"
// Default is false (if not defined) => must input 2 sets of SSID/PWD
#define REQUIRE_ONE_SET_SSID_PW       true

But it's always advisable to use and input both sets for reliability.

11.2 If you need to use both sets of WiFi SSID/PWD

// Permit input only one set of WiFi SSID/PWD. The other can be "NULL or "blank"
// Default is false (if not defined) => must input 2 sets of SSID/PWD
#define REQUIRE_ONE_SET_SSID_PW       false

12. To enable auto-scan of WiFi networks for selection in Configuration Portal

12.1 Enable auto-scan of WiFi networks for selection in Configuration Portal

#define SCAN_WIFI_NETWORKS                  true

The manual input of SSIDs is default enabled, so that users can input arbitrary SSID, not only from the scanned list. This is for the sample use-cases in which users can input the known SSIDs of another place, then send the boards to that place. The boards can connect to WiFi without users entering Config Portal to re-configure.

12.2 Disable manually input SSIDs

// To disable manually input SSID, only from a scanned SSID lists
#define MANUAL_SSID_INPUT_ALLOWED           false

This is for normal use-cases in which users can only select an SSID from a scanned list of SSIDs to avoid typo mistakes and/or security.

12.3 Select maximum number of SSIDs in the list

The maximum number of SSIDs in the list is selectable from 2 to 15 (for ESP8266/ESP32-AT shields, from 2-6). If invalid number of SSIDs is selected, the default number of 10 will be used.

// From 2-15
#define MAX_SSID_IN_LIST                    8

13. To avoid blocking in loop when WiFi is lost

13.1 Max times to try WiFi per loop

To define max times to try WiFi per loop() iteration. To avoid blocking issue in loop()

Default is 1 if not defined, and minimum is forced to be 1.

To use, uncomment in defines.h.

Check retries block the main loop #18

#define MAX_NUM_WIFI_RECON_TRIES_PER_LOOP     2

13.2 Interval between reconnection WiFi if lost

Default is no interval between reconnection WiFi times if lost WiFi. Max permitted interval will be 10mins.

Uncomment to use. Be careful, WiFi reconnection will be delayed if using this method.

Only use whenever urgent tasks in loop() can't be delayed. But if so, it's better you have to rewrite your code, e.g. using higher priority tasks.

Check retries block the main loop #18

#define WIFI_RECON_INTERVAL                   30000     // 30s

Examples

  1. Portenta_H7_WiFi
  2. Portenta_H7_WiFi_MQTT

So, how it works?

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

After you connected, please, go to http://192.168.3.1, you'll see this Main page:

Enter your credentials,

1. Without SCAN_WIFI_NETWORKS

2. With SCAN_WIFI_NETWORKS

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

  1. 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.
  2. 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.
  3. 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

1. 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;

2. 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;

3. Example of Default Credentials

/// Start Default Config Data //////////////////

/*

{
  char wifi_ssid[SSID_MAX_LEN];
  char wifi_pw  [PASS_MAX_LEN];

};

#else

bool LOAD_DEFAULT_CONFIG_DATA = false;

Important Notes for using Dynamic Parameters' ids

  1. These ids (such as "mqtt" in example) must be unique.

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

Troubleshooting

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

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

Issues

Submit issues to: WiFiManager_Portenta_H7_Lite issues

TO DO

  1. Support more boards, shields and libraries
  2. Bug Searching and Killing

DONE

  1. Add support to Portenta_H7 built-in Murata WiFi using ArduinoCore-mbed mbed_portenta core
  2. More flexible to configure reconnection timeout.
  3. For fresh config data, don't need to wait for connecting timeout before entering config portal.
  4. If the config data not entered completely (SSIDs, Passwords, etc.), entering config portal
  5. Add configurable Config Portal IP, SSID and Password
  6. Change Synch XMLHttpRequest to Async
  7. Add configurable Static IP, GW, Subnet Mask and 2 DNS Servers' IP Addresses.
  8. Add checksums
  9. Add MultiWiFi features with auto(re)connect
  10. Easy-to-use Dynamic Parameters without the necessity to write complicated ArduinoJSon functions
  11. Permit to input special chars such as % and # into data fields.
  12. Default Credentials and dynamic parameters
  13. DoubleDetectDetector to force Config Portal when double reset is detected within predetermined time, default 10s.
  14. Configurable Config Portal Title
  15. Re-structure all examples to separate Credentials / Defines / Dynamic Params / Code so that you can change Credentials / Dyamic Params quickly for each device.
  16. Add Table of Contents and Version String
  17. Configurable Customs HTML Headers, including Customs Style, Customs Head Elements, CORS Header
  18. Add functions to control Config Portal from software or Virtual Switches.
  19. Permit optionally inputting one set of WiFi SSID/PWD by using REQUIRE_ONE_SET_SSID_PW == true
  20. Enforce WiFi Password minimum length of 8 chars
  21. Enable scan of WiFi networks for selection in Configuration Portal
  22. Add LibraryPatches for Adafruit_MQTT_Library to fix compiler error for Portenta_H7, RP2040-based and many other boards.
  23. Fix the blocking issue in loop() with configurable WIFI_RECON_INTERVAL
  24. Workaround for core WiFi.status() bug, which does not detect WiFi lost.
  25. Use WiFiMulti_Generic library to connect to the best of multi-WiFi APs, with auto-checking / auto-reconnecting features when WiFi connection is lost
  26. Rewrite for new mbed_portenta core v3.0.1+
  27. Add lib_ldf_mode = chain+ in platformio.ini
