Compile error with Arduino Nano RP2040

[Sirpercal]

Arduino:1.8.15 Hourly Build 2021/05/19 12:35 (Mac OS X 10.14.6), Board : "Arduino Nano RP2040 Connect"
mbed_nano/2.4.1

I've try to compile the simple WebSocket Client example with the changes:

#if ( defined(ARDUINO_ARDUINO_NANO33BLE) || defined(ARDUINO_ARCH_SAMD) || defined(ARDUINO_ARCH_MBED_RP2040) || defined(ARDUINO_ARCH_RP2040) )
#define WEBSOCKETS_USE_WIFININA           true
#else
#error This code is intended to run only on the RP2040 boards ! Please check your Tools->Board setting.
#endif

#if defined(WEBSOCKETS_WIFININA_USE_NRF52)

#if defined(ARDUINO_ARDUINO_NANO33BLE)
#define BOARD_TYPE      "ARDUINO_ARDUINO_NANO33BLE"
#elif defined(ARDUINO_ARCH_SAMD)
#define BOARD_TYPE      "ARDUINO_ARCH_SAMD"
#elif defined(ARDUINO_ARCH_MBED_RP2040)
#define BOARD_TYPE      "ARDUINO_ARCH_MBED_RP2040"
#elif defined(ARDUINO_ARCH_RP2040)
#define BOARD_TYPE      "ARDUINO_ARCH_RP2040"
#else
#define BOARD_TYPE      "RP2040 Unknown"
#endif

#endif

And get this compile error:

Hi Robert,

Thanks for your interest in the library.

Currently, Nano_RP2040_Connect board is not supported, as somehow I forgot to add its support and will do it ASAP.
Some modifications in the library, in addition to those in the sketch, are necessary.

Will let you know soon,

Best,

Hi Robert,

The new WebSockets2_Generic releases v1.8.0 has just been published.

Check the new RP2040 examples

Your contribution has been noted in Contributions and Thanks

Please test and report any issue

Best Regards,

---

Major Release v1.8.0

1. Add support to RP2040-based boards, such as Nano_RP2040_Connect, RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040, using WiFiNINA
2. Add examples with new features
3. Update many Packages' Patches
