Why do we need this BlynkEthernet_Manager library

Features

This is a Blynk and WiFiManager Library for configuring/auto(re)connecting boards to available MultiBlynk servers at runtime. Connection is with or without SSL. Configuration data to be saved in either LittleFS, SPIFFS, EEPROM, DueFlashStorage or FlashStorage. Default Credentials as well as Dynamic custom parameters can be added and modified easily without coding knowledge.

DoubleResetDetector is used to force Config Portal opening even if the Credentials are still valid.

This is the new library, adding to the current Blynk_WiFiManager. It's designed to help you eliminate hardcoding your Blynk credentials in Teensy, SAM DUE, SAMD21, SAMD51, nRF52, ESP8266, ESP32, RP2040-based, etc. boards using Ethernet shields (W5200, W5500, ENC28J60, Teensy 4.1 NativeEthernet, etc). It's currently not supporting SSL.

  • It's not supporting UNO/Nano/Mega and other AVR boards for not enough memory.
  • You can update Blynk Credentials any time you need to change via Configure Portal. Data are saved in configurable locations in LittleFS, SPIFFS, EEPROM, DueFlashStorage or FlashStorage
  • Teensy LC, 2.0++ and 2.0 not supported.
  • 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

The RP2040-based boards, such as Nano_RP2040_Connect, RASPBERRY_PI_PICO, are currently supported using Earle Philhower's arduino-pico core v1.4.0+ or Arduino-mbed RP2040 core with Blynk/WiFiManager features thanks to LittleFS support.

New recent features:

  • MultiBlynk feature for configuring/auto(re)connecting boards to one of the available MultiBlynk Servers 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

HOWTO Install esp32 core for ESP32-S2 (Saola, AI-Thinker ESP-12K) and ESP32-C3 boards into Arduino IDE

These are instructions demonstrating the steps to install esp32-s2/c3 core on Ubuntu machines. For Windows or other OS'es, just follow the the similar principles and steps.

https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json

and have Board Manager auto-install the development esp32 core. For example : esp32 core v2.0.0-alpha1


If you're already successful in testing the core, after installing by using the above procedures, you don't need to follows the hereafter manual steps.


Assuming you already installed Arduino IDE ESP32 core and the installed directory is

/home/your_account/.arduino15/packages/esp32

1. Save the original esp32 core

First, copy the whole original esp32 core to another safe place. Then delete all the sub-directories of

/home/your_account/.arduino15/packages/esp32/hardware/esp32/1.0.4


2. Install esp32 core v1.0.6

2.1 Install esp32 core

Just use Arduino IDE Board Manager to install ESP32 Arduino Release 1.0.6 based on ESP-IDF v3.3.5. This official v1.06 core doesn't have esp32-s2/s3 support. You have to download and use the latest master branch.

2.2 Download latest zip with esp32-s2 support

As of April 16th 2021, the esp32-s2/c3 board support has been included in master branch of esp32 core. Download esp32 core, master branch in the zip format.

2.3 Unzip

2.4 Update esp32 core directories

Copy all subdirectories of esp32 core into /home/your_account/.arduino15/packages/esp32/hardware/esp32/1.0.6


3 Download tools for ESP32-S2

3.1 Download Toolchain for Xtensa (ESP32-S2) based on GCC

Download esp32-s2 Toolchain corresponding to your environment (linux-amd64, win64, etc.).

For example xtensa-esp32s2-elf-gcc8_4_0-esp-2020r3-linux-amd64.tar.gz, then un-archive.

3.2 Download esptool

Download esptool int the zip format:

then copy whole riscv32-esp-elf directory into /home/your_account/.arduino15/packages/esp32/hardware/esp32/1.0.6/tools

6. esp32-s2 WebServer Library Patch

Necessary only for esp32 core v1.0.6-

If you haven't installed a new version with WebServer.handleClient delay PR #4350 or haven't applied the above mentioned PR, you have to use the following patch.

To be able to run Config Portal on ESP32-S2 boards, you have to copy the files in esp32-s2 WebServer Patch directory into esp32-s2 WebServer library directory (~/.arduino15/packages/esp32/hardware/esp32/1.0.4/libraries/WebServer).

Supposing the esp32-s2 version is 1.0.4, these files WebServer.h/cpp must be copied into the directory to replace:

  • ~/.arduino15/packages/esp32/hardware/esp32/1.0.4/libraries/WebServer/src/WebServer.h
  • ~/.arduino15/packages/esp32/hardware/esp32/1.0.4/libraries/WebServer/src/WebServer.cpp

That's it. You're now ready to compile and test for ESP32-S2 and ESP32-C3 now



Note for Platform IO using ESP32 LittleFS

In Platform IO, to fix the error when using LittleFS_esp32 v1.0 for ESP32-based boards with ESP32 core v1.0.4- (ESP-IDF v3.2-), uncomment the following line

from

//#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */

to

#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */

It's advisable to use the latest LittleFS_esp32 v1.0.6+ to avoid the issue.

Thanks to Roshan to report the issue in Error esp_littlefs.c 'utime_p'



HOWTO Use analogRead() with ESP32 running WiFi and/or BlueTooth (BT/BLE)

Please have a look at ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to have more detailed description and solution of the issue.

1. ESP32 has 2 ADCs, named ADC1 and ADC2

2. ESP32 ADCs functions

  • ADC1 controls ADC function for pins GPIO32-GPIO39
  • ADC2 controls ADC function for pins GPIO0, 2, 4, 12-15, 25-27

3.. ESP32 WiFi uses ADC2 for WiFi functions

Look in file adc_common.c

In ADC2, there're two locks used for different cases:

  1. lock shared with app and Wi-Fi: ESP32: When Wi-Fi using the ADC2, we assume it will never stop, so app checks the lock and returns immediately if failed. ESP32S2: The controller's control over the ADC is determined by the arbiter. There is no need to control by lock.

  2. lock shared between tasks: when several tasks sharing the ADC2, we want to guarantee all the requests will be handled. Since conversions are short (about 31us), app returns the lock very soon, we use a spinlock to stand there waiting to do conversions one by one.

adc2_spinlock should be acquired first, then adc2_wifi_lock or rtc_spinlock.

  • In order to use ADC2 for other functions, we have to acquire complicated firmware locks and very difficult to do
  • So, it's not advisable to use ADC2 with WiFi/BlueTooth (BT/BLE).
  • Use ADC1, and pins GPIO32-GPIO39
  • If somehow it's a must to use those pins serviced by ADC2 (GPIO0, 2, 4, 12, 13, 14, 15, 25, 26 and 27), use the fix mentioned at the end of ESP_WiFiManager Issue 39: Not able to read analog port when using the autoconnect example to work with ESP32 WiFi/BlueTooth (BT/BLE).


Important Notes

  1. Code is restructured to provide flexibility to make it easy to support many more WiFi/Ethernet modules/shields in the future. Please delete the *.cpp files, replaced by *.hpp files, in the src directory, if *.cpp files still exist after installing new version.

  2. For Adafruit nRF52, use the SPI's pin as follows:

  • SS/CS = 10
  • SPI_MOSI = MO(SI)
  • SPI_MISO = MI(SO)
  • SPI_SCK = SCK
  1. For Adafruit SAMD21/SAMD51, use the SPI's CS/SS pin as follows:
  • Itsy-Bitsy M0/M4, Feather M0 (Express), Hallowing M0 Express, Zero, Metro M0 => use CS = 16 = pin A2
  • Feather M4 (SAMD51) => use SS/CS = 9
  • Grand Central M4 => use SS/CS = 53
  • Hallowing M4 => use SS/CS = 10
  • Metro M4 AirLift => use SS/CS = 36

To know the default CS/SS pins of not listed boards, check the related variant.h files in

~/.arduino15/packages/adafruit/hardware/samd/x.y.zz/variants/board_name/variant.h

  1. For Arduino SAM DUE, use the SPI's pin as follows:



Configuration Notes

1. How to select which built-in Ethernet or shield to use

The easiest way is to use

#define USE_ETHERNET_WRAPPER    true

then select one and only one Ethernet library to use as follows:

  • Standard W5x00 Ethernet library is used by default, in the sketch, just be sure to comment out or leave these #defines to be false :
#define USE_UIP_ETHERNET        false

// Only one if the following to be true
#define USE_ETHERNET          true
#define USE_ETHERNET2         false

#define USE_ETHERNET_ESP8266    false
#define USE_ETHERNET_ENC        true
#define USE_CUSTOM_ETHERNET     false
  • To use ENC28J60 Ethernet, using UIPEthernet library:

#define USE_ETHERNET_ESP8266    false
#define USE_ETHERNET_ENC        false
#define USE_CUSTOM_ETHERNET     false
  • To use any of the Ethernet libraries, such as Ethernet2, Ethernet3, EthernetLarge, EthernetENC:
#define USE_UIP_ETHERNET        false

// Only one if the following to be true
#define USE_ETHERNET            false
#define USE_ETHERNET2           false

#define USE_ETHERNET_LARGE      false
#define USE_ETHERNET_ESP8266    false
#define USE_ETHERNET_ENC        false
#define USE_CUSTOM_ETHERNET     false
  • To use another Ethernet library For example, Ethernet_XYZ library uses Ethernet_XYZ.h
#define USE_UIP_ETHERNET        false

// Only one if the following to be true
#define USE_ETHERNET            false
#define USE_ETHERNET2           false

//Must be placed before #include <EthernetWebServer.h>
#include <Ethernet_XYZ.h>
...

#include <EthernetWebServer.h>
  • Only for Teensy 4.1, to use NativeEthernet library
#if defined(__IMXRT1062__)
    // For Teensy 4.1/4.0
    #if defined(ARDUINO_TEENSY41)
      #define BOARD_TYPE      "TEENSY 4.1"
      // Use true for NativeEthernet Library, false if using other Ethernet libraries
      #define USE_NATIVE_ETHERNET     true

      #define BOARD_TYPE      "TEENSY 4.0"
    #else
      #define BOARD_TYPE      "TEENSY 4.x"
    #endif      
  #elif defined(__MK66FX1M0__)
  ....
  • Only for Teensy 4.1, to use another Ethernet library, for example Ethernet3 library
#if defined(__IMXRT1062__)
  // For Teensy 4.1/4.0
  #if defined(ARDUINO_TEENSY41)
    #define BOARD_TYPE      "TEENSY 4.1"

#define USE_ETHERNET_LARGE      false
#define USE_ETHERNET_ESP8266    false
#define USE_ETHERNET_ENC        false
#define USE_CUSTOM_ETHERNET     false  

Important:

  • The Ethernet_Shield_W5200, EtherCard, EtherSia libraries are not supported. Don't use unless you know how to modify those libraries.
  • Requests to support for any future custom Ethernet library will be ignored. Use at your own risk.

2. How to select another CS/SS pin to use

The default CS/SS pin is GPIO4(D2) for ESP8266, GPIO22 for ESP32, 10 for all other boards.

If the default pin is not corect, the easiest way is to change is to use

#define USE_ETHERNET_WRAPPER    true

then select the CS/SS pin (e.g. 22) to use as follows:

// To override the default CS/SS pin. Don't use unless you know exactly which pin to use
#define USE_THIS_SS_PIN   22

3. How to use W5x00 with ESP8266

To avoid using the default but not-working Ethernet library of ESP8266, rename the Ethernet.h/cpp to Ethernet_ESP8266.h/cpp to avoid library conflict if you're using the Arduino Ethernet library. The Ethernet2, Ethernet3, EthernetLarge library can be used without conflict.

These pins are tested OK with ESP8266 and W5x00

  // For ESP8266
  // Pin                D0(GPIO16)    D1(GPIO5)    D2(GPIO4)    D3(GPIO0)    D4(GPIO2)    D8
  // Ethernet           0                 X            X            X            X        0
  // Ethernet2          X                 X            X            X            X        0
  // Ethernet3          X                 X            X            X            X        0
  // EthernetLarge      X                 X            X            X            X        0
  // Ethernet_ESP8266   0                 0            0            0            0        0
  // D2 is safe to used for Ethernet, Ethernet2, Ethernet3, EthernetLarge libs
  // Must use library patch for Ethernet, EthernetLarge libraries
  //Ethernet.setCsPin (USE_THIS_SS_PIN);
  Ethernet.init (USE_THIS_SS_PIN);

4. How to increase W5x00 TX/RX buffer

  • For Ethernet3 library only, use as follows
  // Use  MAX_SOCK_NUM = 4 for 4K, 2 for 8K, 1 for 16K RX/TX buffer
  #ifndef ETHERNET3_MAX_SOCK_NUM
    #define ETHERNET3_MAX_SOCK_NUM      4
  #endif
  
  Ethernet.setCsPin (USE_THIS_SS_PIN);
  Ethernet.init (ETHERNET3_MAX_SOCK_NUM);


How to use

In your code, replace

  1. BlynkSimpleEthernet.h with BlynkSimpleEthernet_WM.h for board using W5x00 without SSL
  2. BlynkSimpleEthernet2.h with BlynkSimpleEthernet2_WM.h for board using only W5500 without SSL
  3. BlynkSimpleEthernetV2_0.h with BlynkSimpleEthernetV2_0_WM.h for board using only W5500 without SSL
  4. BlynkSimpleUIPEthernet.h with BlynkSimpleUIPEthernet_WM.h for board using ENC28J60 and UIPEthernet library without SSL
  5. BlynkSimpleEthernetSSL.h with BlynkSimpleEthernetSSL_WM.h for other boards (not Mega) using W5200, W5500 with SSL (not working yet)
  6. BlynkSimpleEthernetSSL.h with BlynkSimpleUIPEthernetSSL_WM.h for other AVR boards (not Mega) using ENC28J60 with SSL (not working yet)
  7. BlynkSimpleEthernet.h with BlynkSimpleEthernetENC_WM.h for board using ENC28J60 and EthernetENC library without SSL
// Start location to store config data to avoid conflict with other functions
#define EEPROM_START   0

Then replace Blynk.begin(...) with :

  1. Blynk.begin()

in your code. Keep Blynk.run() intact.

That's it.

5. If you don't need to add dynamic parameters

Use the following in sketch

#define USE_DYNAMIC_PARAMETERS     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:

"sv"    for Blynk Server
"tk"    for Blynk Token
"sv1"   for Blynk Server1
"tk1"   for Blynk Token1
"pt"    for Blynk Port
"ip"    for Static IP Address
"nm"    for Board Name


Why using this BlynkEthernet_Manager with MultiBlynk features

You can see that the system automatically detects and connects to the avaiable Blynk Servers, whenever interruption happens. This feature is very useful for systems requiring high degree of reliability.

Moreover, this Blynk.begin() is not a blocking call, so you can use it for critical functions requiring in loop().

Anyway, this is better for projects using Blynk just for GUI (graphical user interface).

In operation, if WiFi or Blynk connection is lost, Blynk.run() will try reconnecting automatically. Therefore, Blynk.run() must be called in the loop() function. Don't use:

void loop()
{
  if (Blynk.connected())
     Blynk.run();
     
  ...
}

just

void loop()
{
  Blynk.run();
  ...
}

So, how it works?

If no valid config data are stored in EEPROM, it will switch to Configuration Mode. Connect to access point at the IP address displayed on Terminal or Router's DHCP server as in the following picture:

After you connected to, for example, 192.168.2.86, the Browser will display the following picture:

Enter your credentials (Blynk Servers/Tokens and Port). If you prefer static IP, input it (for example 192.168.2.220) in the corresponding field. Otherwise, just leave it blank or nothing to use auto IP assigned by DHCP server.

Then click Save. After the board auto-restarted, you will see if it's connected to your Blynk server successfully as in the following picture:

This Blynk.begin() is not a blocking call, so you can use it for critical functions requiring in loop(). Anyway, this is better for projects using Blynk just for GUI (graphical user interface).

In operation, if Ethernet or Blynk connection is lost, Blynk.run() will try reconnecting automatically. Therefore, Blynk.run() must be called in the loop() function. Don't use:

void loop()
{
  if (Blynk.connected())
     Blynk.run();
     
  ...
}

just

void loop()
{
  Blynk.run();
  ...
}

Debug

Debug is enabled by default on Serial.

You can also change the debugging level from 0 to 4

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

// Debug Level from 0 to 4
#define _ETHERNET_WEBSERVER_LOGLEVEL_       1

#if ( defined(ESP32) || defined(ESP8266) )
  #define DOUBLERESETDETECTOR_DEBUG     false   //true
#else
  #define DRD_GENERIC_DEBUG             false   //true
#endif

#define BLYNK_WM_DEBUG                      0

Troubleshooting

If you get compilation errors, more often than not, you may need to install a newer version of the core for Arduino boards.

Sometimes, the library will only work if you update the board core to the latest version because I am using newly added functions.



Issues

Submit issues to: BlynkEthernet_Manager issues


TO DO

  1. Same features for other boards with new Ethernet shields.
  2. Add SSL/TLS Client and Server support. Currently, Ethernet SSL is not supported by Blynk code yet.
  3. Bug Searching and Killing
  4. Support more non-compatible Ethernet Libraries such as Ethernet_Shield_W5200, EtherCard, EtherSia.

DONE

  1. Permit EEPROM size and location configurable to avoid conflict with others.
  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 (Serves, HardwarePort and Blynk tokens), entering config portal
  5. Change Synch XMLHttpRequest to Async
  6. Reduce memory usage.
  7. Support ENC28J60 as well as W5200/W5500 Ethernet shields
  8. Add checksums
  9. Support SAM DUE, SAMD, Teensy boards
  10. Support STM32 boards
  11. Add MultiBlynk features with Auto(Re)Connect to the available Server.
  12. Easy-to-use Dynamic Parameters without the necessity to write complicated ArduinoJSon functions
  13. Permit to input special chars such as % and # into data fields.
  14. Support more types of boards using Ethernet shields : nRF52 boards, such as AdaFruit Feather nRF52832, nRF52840 Express, BlueFruit Sense, Itsy-Bitsy nRF52840 Express, Metro nRF52840 Express, NINA_B302_ublox, etc. Default Credentials and dynamic parameters
  15. DoubleDetectDetector to force Config Portal when double reset is detected within predetermined time, default 10s.
  16. Configurable Config Portal Title
  17. Re-structure all examples to separate Credentials / Defines / Dynamic Params / Code so that you can change Credentials / Dynamic Params quickly for each device.
  18. Add LittleFS support to ESP8266 as SPIFFS deprecated since ESP8266 core 2.7.1.
  19. Auto format SPIFFS/LittleFS for first time usage
  20. Add support to Seeeduino SAMD21/SAMD51 boards (SEEED_WIO_TERMINAL, SEEED_FEMTO_M0, SEEED_XIAO_M0, Wio_Lite_MG126, WIO_GPS_BOARD, SEEEDUINO_ZERO, SEEEDUINO_LORAWAN, SEEED_GROVE_UI_WIRELESS, etc.)
  21. Add support to new EthernetENC library for ENC28J60.
  22. Add support to LittleFS for ESP32 using LITTLEFS Library
  23. Add support to NativeEthernet Library for Teensy 4.1
  24. Add Table of Contents and Version String
  25. Add support to ESP32-S2 (ESP32-S2 Saola, AI-Thinker ESP-12K, etc.)
  26. Add support to RP2040-based boards, such as RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040, using Earle Philhower's arduino-pico core to use LittleFS with or without Blynk/WiFiManager features.
  27. Add support to RP2040-based boards, such as Nano_RP2040_Connect, RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040, using Arduino-mbed RP2040 core to use LittleFS with or without Blynk/WiFiManager features.


Contributions and Thanks

  1. Thanks to thorathome in GitHub to test, suggest and encourage to add those new features to Blynk_WM, such as Default Credentials/Dynamic Params, Configurable Config Portal Title, DRD. Those features are included in this library now.
  2. Thanks to Miguel Alexandre Wisintainer for initiating, inspriring, working with, developing, debugging and testing. See ESP32-based U-BLOX NINA W102 running ENC28J60.
