Support for Arduino Nano 33 BLE (Sense)
Now that the Arduino Nano 33 BLE and Arduino Nano 33 BLE Sense have been released and introduce:
- First genuine Arduino board based on Nordic nRF52840
- Arduino core based on Mbed OS framework
Are there any plans to bring them to PlatformIO? What will be needed? How can it be supported?
What would be needed to add support and close this issue? We're designing a nano 33 shield, and I would love to add PlatformIO support to the library. Is it a matter of adding a configuration file to the boards folder? or are there other changes that need to be made? If there is any way we can help add the nano 33 BLE boards to the PlatformIO system we'd be happy to help.
Should it rely on the ArduinoCore running on MBEDos or directly on MBEDos ?
I would prefer if priority was given to the Arduino core based on Mbed OS framework. This is likely the better solution for most users and in particular for users coming from the Arduino IDE.
In case anyone starts to work on this: the Arduino guys managed to build the nRF52 Arduino core upon an untagged branch of the Arduino Core API, namely the arduino_namespace branch. Those sources are needed and not part of the Arduino core based on Mbed OS framework.
This have anything to do with anything? https://github.com/arduino/ArduinoCore-nRF528x-mbedos
We've added support for this board, but we didn't try it on real hardware, so it would be great if someone could try to compile and upload a basic example.
Thanks!
Thanks, @valeros! Please note that you will need to use development version of platform:
[env:myenv]
platform = https://github.com/platformio/platform-nordicnrf52.git
framework = arduino
board = nano33ble
I just happened to play with a NANO33BLE board this evening and ran into this thread. Using the platformio config above, it compiles for me.
Uploading didn't work for me yet. The first problem is that ~/.platformio/platforms/nordicnrf52/builder/main.py has an unresolved symbol basename (line 48). I fixed that by changing a line from from os.path import isdir, join to from os.path import isdir, join, basename
The second problem is some kind of uploading problem:

I do have the same problem as @bertrik. Importing basename from os.path fixed initial Python Error, but now I am getting No device found on ... error. I have manually selected upload_port in ini file but the problem remains. Building seems alright.

Thanks @bertrik @vaetas. I fixed missing basename import and also added some modifications to the upload process. Could you please pull the latest changes and try again? Simple pio update command should be enough if there is no conflicts with your changes.
Thanks for the work on the Arduino Nano 33. I've tested it and it looks quite good already. The project compiles and compilation times are much faster than in Arduino IDE (where it's extremly slow).
There are a number of issues though:
1. Upload
Same problem as @bertrik and @vaetas. The path to the USB port is correct. And upload works from the Arduino IDE.
The output from pio run -v -t upload is:
<lambda>(["upload"], [".pio/build/nano33ble/firmware.bin"])
AVAILABLE: cmsis-dap, jlink, nrfjprog, nrfutil, sam-ba
CURRENT: upload_protocol = sam-ba

No device found on cu.usbmodem144401

Send auto-baud

*** [upload] Error 1
As a comparison, the Arudino IDE uses the below command:
/Users/me/Library/Arduino15/packages/arduino/tools/bossac/1.9.1-arduino1/bossac --port=cu.usbmodem144401 -U -i -e -w /var/folders/z2/t5tl6v7d2k95p70t98gd_wqw0000gn/T/arduino_build_635165/BatteryMonitor.ino.bin -R
I tried a similar command using the PlatformIO's bossac, and it worked once and then stopped to work (No device found...).
But PlatformIO's upload task works if I double click the board's reset button first. The LED then goes in a fade in / fade out mode.
2. Intellisense
In a simple Blink sketch, #include <Arduino.h> has squiggly red lines and the error message is
#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit (/Users/me/Documents/PlatformIO/Projects/Nano-33-BLE/src/main.cpp).
cannot open source file "USBDescriptor.h" (dependency of "Arduino.h")
The missing file changed over time. It was mbed.h earlier.
In c_cpp_properties.json, the following include paths are listed:
"/Users/me/Documents/PlatformIO/Projects/Nano-33-BLE/include",
"/Users/me/Documents/PlatformIO/Projects/Nano-33-BLE/src",
"/Users/me/.platformio/packages/framework-arduino-nrf52-mbedos/cores/arduino",

"/Users/me/.platformio/packages/tool-unity",
""
Possibly, directories are missing such as cores/arduino/mbed and cores/arduino/mebed/drivers/internal.
3. Create a new project
Creating a new project with the nano33ble board from PIO Home fails. The project is successfully created. But instead of opening it, an error message is displayed:
Could not initialize project
PIO Core Call Error: "The current working directory /Users/me/Documents/PlatformIO/Projects/Nano-33-Test2 will be used for the project.\n\nThe next files/directories have been created in /Users/me/Documents/PlatformIO/Projects/Nano-33-Test2\ninclude - Put project header files here\nlib - Put here project specific (private) libraries\nsrc - Put project source files here\nplatformio.ini - Project Configuration File\n\n\nError: Unknown board ID 'nano33ble'"
More or is likely to come... I will continue to test.
Thanks for your help @valeros. I have pulled your changed but the error persisted.

I have the upload working now. I uploaded the BatteryMonitor example from the ArduinoBLE library and I can see a "BatteryMonitor" device now in a BLE scanner on my Android phone.
What have you changed @bertrik. The Arduino gets into bootloader mode when I press Upload (led starts slowly blinking) but immediately fails.
OK, I am not sure what happened but I tried to upload it again and it worked!
@bertrik @vaetas Thanks!
Thanks @manuelbl, good points!
- The uploading should be fixed in the latest version.
- I think that's fixable, this Arduino core has quite unusual form of include flags and that requires some modifications to VSCode project template.
- That's strange, I cannot reproduce it, maybe you have two
nordicnrf52platforms and the stable one is used instead of the latest one from the repository?
Thanks a lot for making this work @valeros!
However, I have one weird problem. When I try to upload binary, Nano will switch to bootloader mode (not sure the correct name) and upload from PIO will then fail with No device found on ttyACM0 error. But when I press Upload again, it will successfully upload. Third upload will again fail and so on.
I have tested this on two different Nano 33 BLEs and the bug appears on both of them. It seems like a problem with Arduino because it apparently closes connection when switching modes before upload. Does this happen to anybody else or is it only my problem? I am currently on Arch Linux.
On my system (debian bullseye/sid) I noticed that I had modemmanager installed. I don't really trust it in the sense that I'm really sure it's not messing with anything that looks like a serial port (/dev/ttyUSBx or /dev/ttyACMx), so I made sure it was not running and uninstalled it. Perhaps this is something you can try too and see if it has an effect on upload success.
Thanks @valeros for the quick response. Regarding my issues:
- Uploading: It's better now but in only works every other time (same as for @vaetas). I think I know why... see below.
- Intellisense: I'm looking forward to a fix.
- Opening project: Yes, I had two platforms (the productive one and the one declared in
platformio.iniaccording to Ivan's instructions). So it won't be an issue anymore once it's officially released?
In the mean time I have also tested it on Windows. It behaves the same (same things working, same open issues). I've also tested J-Link upload and debugging and it works.
Upload
In the Arduino IDE, it works. So what's the difference? It's not the command line arguments for bossac. It seems that the Arduino IDE first resets the board before it starts bossac.
The clue is if the serial port is busy. Then you don't get an error message from bossac but from the Arduino IDE:

The exception is thrown on this line: https://github.com/arduino/Arduino/blob/master/arduino-core/src/processing/app/Serial.java#L107
It's the code for the board reset. It is run if the Arduino board definition contains:
upload.use_1200bps_touch=true
The setting upload.wait_for_upload_port=true is also relevant. It waits for the virtual serial port to reappear after the reset was triggered.
Could that be the missing piece?
@manuelbl Thank you so much for the hint!
@valeros please use reset code from Atmel SAM dev/platform. See “BeforeUpload” pre-action.
Sorry for the late reply, could someone retest uploading with the latest platform version?
@valeros With your latest commit uploading works all the time! I have tested this with the latest development version for nordicnrf52 platform. Brilliant! Thanks.
I updated PlatformIO and the nRF52 package, but I still don't see Arduino Nano BLE Nano among the available boards. What am I doing wrong?
Hi there, could anyone explain the benefits of using PlatformIO rather than the Microsoft Arduino extension? Thanks and great job getting this working!
@fgaetani This feature is not released yet, so you need to use the upstream version of the platform:
[env:myenv]
platform = https://github.com/platformio/platform-nordicnrf52.git
framework = arduino
board = nano33ble
@luke-shields So in a nutshell, PlatformIO is more advanced and customizable ecosystem in comparison with a simple IDE extension like Microsoft Arduino. More detailed info you can find here.
