Whenever a new version is installed, remember to copy these files into the new version directory. For example, new version is x.yy.z These files must be copied into the directory:

• ~/.arduino15/packages/adafruit/hardware/nrf52/x.yy.z/platform.txt
• ~/.arduino15/packages/adafruit/hardware/nrf52/x.yy.z/boards.txt
• ~/.arduino15/packages/adafruit/hardware/nrf52/x.yy.z/variants/NINA_B302_ublox/variant.h
• ~/.arduino15/packages/adafruit/hardware/nrf52/x.yy.z/variants/NINA_B302_ublox/variant.cpp
• ~/.arduino15/packages/adafruit/hardware/nrf52/x.yy.z/variants/NINA_B112_ublox/variant.h
• ~/.arduino15/packages/adafruit/hardware/nrf52/x.yy.z/variants/NINA_B112_ublox/variant.cpp

• ~/.arduino15/packages/Seeeduino/hardware/samd/x.yy.zz/platform.txt

7. To use Serial1 on some STM32 boards without Serial1 definition (Nucleo-144 NUCLEO_F767ZI, Nucleo-64 NUCLEO_L053R8, etc.) boards, you have to copy the files STM32 variant.h into STM32 stm32 directory (~/.arduino15/packages/STM32/hardware/stm32/1.9.0). You have to modify the files corresponding to your boards, this is just an illustration how to do.

Supposing the STM32 stm32 core version is 1.9.0. These files must be copied into the directory:

• ~/.arduino15/packages/STM32/hardware/stm32/1.9.0/variants/NUCLEO_F767ZI/variant.h for Nucleo-144 NUCLEO_F767ZI.

How to configure to use different WiFi Libraries

1. Please change the pin-to-pin connection in ~/Arduino/libraries/src/WiFiNINA_Pinout_Generic.h to match actual connection if using WiFiNINA with WiFiNINA_Generic library.

For example

#elif ( defined(NRF52840_FEATHER) || defined(NRF52832_FEATHER) || defined(NRF52_SERIES) || defined(ARDUINO_NRF52_ADAFRUIT) || \
        defined(NRF52840_FEATHER_SENSE) || defined(NRF52840_ITSYBITSY) || defined(NRF52840_CIRCUITPLAY) || defined(NRF52840_CLUE) || \
        defined(NRF52840_METRO) || defined(NRF52840_PCA10056) || defined(PARTICLE_XENON) || defined(NINA_B302_ublox) || defined(NINA_B112_ublox) )

  #warning You have to modify pin usage accoring to actual connection for NRF528XX
  // To define pin out for WiFiNINA here

  //#define PINS_COUNT           (60u)
  //NINA
  #define NINA_GPIO0  (26u)                             //26
  #define NINA_RESETN (27u)
  #define NINA_ACK    (28u)

  #define SPIWIFI_SS       24   //PIN_SPI1_SS            //24
  #define SPIWIFI_ACK      28   //NINA_ACK               //28 
  #define SPIWIFI_RESET    27   //NINA_RESETN            //27

2. How to select which built-in WiFi or shield to use

• To use W102-based WiFiNINA, define in the sketch:

#define USE_WIFI_NINA         true

• To use built-in WiFi101 or shield:

#define USE_WIFI_NINA         false
#define USE_WIFI101           true

• To use MKR1000 with built-in WiFi101:

// Don't care false ot true
#define USE_WIFI_NINA         false

• For boards other than MKR1000, to use another WiFi library with the standard WiFi.h, such as WiFiEspAT library library

#define USE_WIFI_NINA         false

• To use another WiFi library without the standard WiFi.h

For example, WiFi_XYZ library uses WiFi_XYZ.h

#define USE_WIFI_NINA         false
#define USE_WIFI_CUSTOM       true

...
//Must be placed before #include <WiFiWebServer.h>
#include <WiFi_XYZ.h>
#include <WiFiWebServer.h>

Important:

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

Contributions and Thanks

1. Based on and modified from Ivan Grokhotkov's ESP8266WebServer
2. Thanks to good work of Miguel Alexandre Wisintainer for initiating, inspriring, working with, developing, debugging and testing. Without that, support to nRF52, especially U-Blox B302 running as nRF52840 and U-Blox B112 running as nRF52832, has never been started and finished. See u-blox nina b
