Arduino Nano RP2040 with ArduinoBLE-library

Development Platforms

I am trying to use RP2040 board with ArduinoBLE-library. This lib accesses HCIUartTransport, giving error

.pio\libdeps\nanorp2040connect\ArduinoBLE\src\utility\HCIUartTransport.cpp:33:2: error: #error "Unsupported board selected!"
   33 | #error "Unsupported board selected!"
      |  ^~~~~
*** [.pio\build\nanorp2040connect\libd5f\ArduinoBLE\utility\HCIUartTransport.cpp.o] Error 1

Looking at the code in that file:

#if !defined(ARDUINO_ARCH_MBED) || defined(TARGET_NANO_RP2040_CONNECT)

#include "HCIUartTransport.h"

#if defined(ARDUINO_SAMD_MKRWIFI1010) || defined(ARDUINO_AVR_UNO_WIFI_REV2)
#define SerialHCI Serial2
#elif defined(ARDUINO_SAMD_NANO_33_IOT) || defined(ARDUINO_NANO_RP2040_CONNECT)
// SerialHCI is already defined in the variant
#elif defined(ARDUINO_PORTENTA_H7_M4)
// SerialHCI is already defined in the variant
#elif defined(ARDUINO_PORTENTA_H7_M7)
#define SerialHCI Serial2
#else
#error "Unsupported board selected!"
#endif

I added the following build flags to platform.ini:

build_flags = -DTARGET_NANO_RP2040_CONNECT
                     -DARDUINO_NANO_RP2040_CONNECT

But it still gives the same error.

This is related to my previous
question: Arduino Nano RP2040 Connect, blinking RGB led does not compile - #4 by maxgerhardt

What is wrong in my build-flags ?

I have no problems building a sketch with ArduinoBLE and the current raspberrypi platform version.

platformio.ini does not need to be specially modified with build flags.

[env:nanorp2040connect]
platform = raspberrypi
board = nanorp2040connect
framework = arduino
lib_deps =
     arduino-libraries/ArduinoBLE @ ^1.2.1

with src\main.cpp

#include <Arduino.h>
#include <ArduinoBLE.h>

void setup() {}
void loop() {}

gives me

Try opening a CLI and execute

pio platform update raspberrypi

to make sure you have the latest version.

If that does not help, post the complete platformio.ini and minimal code.

Thanks a lot, updating from 1.1.0 to version 1.2.0 solved the issue,
and build flags are not needed anymore !
