Remark on "Arduino Nano RP2040 Connect" of "Arduino Mbed OS Boards" vs "Arduino Mbed OS Nano Boards"

It's my case of selecting "Arduino Nano RP2040 Connect" of "Arduino Mbed OS Boards" vs "Arduino Mbed OS Nano Boards".

The case is:

I have both Arduino Nano RP2040 Connect and Seeed XIAO BLE (Sense).

To program in Arduino IDE (1.8.15), follow this post (in my another blogspot) to install Arduino Mbed OS Nano Boards for Arduino Nano RP2040 Connect, and follow former post to install Seeed nRF52 Boards for Seeed XIAO nRF52840 Sense.

After then, there are two selection of "Arduino Nano RP2040 Connect" from "Arduino Mbed OS Boards" and "Arduino Mbed OS Nano Boards".

Case I - "Arduino Nano RP2040 Connect" from "Arduino Mbed OS Boards", actually it come from Seeed nRF52 Boards 2.6.1:

Select board "Arduino Nano RP2040 Connect" from "Arduino Mbed OS Boards"

If you have ArduinoBLE library installed, its examples is located within INCOMPATIBLE.

If you compile any example, even Blink, error will be reported!

Arduino: 1.8.15 (Linux), Board: "Arduino Nano RP2040 Connect"

WARNING: library ArduinoBLE claims to run on samd, megaavr, mbed, apollo3, mbed_nano, mbed_portenta architecture(s) and may be incompatible with your current board which runs on nrf52 architecture(s).

Error compiling for board Arduino Nano RP2040 Connect.


This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Case II - "Arduino Nano RP2040 Connect" from"Arduino Mbed OS Nano Boards" 2.8.0:

Select board "Arduino Nano RP2040 Connect" from "Arduino Mbed OS Nano Boards"

Now ArduinoBLE example is located under Custom Libraries.

Compile and Upload without error.
