Unable to use latest Arduino IDE with nRF52840

Gabriel · April 3, 2023, 4:04pm

OS: MacOS 13.3
IDE: Arduino 2.0.4
Board: Seeed XIAO nRF52840

I’ve got the following error while trying to compile the sketch(any):

Any idea how to solve this?

This error occurs because the default encoding for your Python environment is set to ASCII, which can cause issues when working with non-ASCII characters.

To fix this error, you need to set your default Python encoding to UTF-8. Here are the steps to do it:

Open the terminal on your Mac.

Run the command below to open your bash profile:

bash
Copy code
nano ~/.bash_profile
Add the following line at the end of the file:
arduino
Copy code
export LC_ALL=en_US.UTF-8
Press Control + X to exit nano and save the changes.

Close the terminal and reopen it.

Try compiling your sketch again.

This should solve the error you’re experiencing.

Which example did you use to run it?
You first check to see if you have successfully added the libraries needed for the example in arduino.
I hope I can help you.

In my case it didn’t help.

Yes, I’m also having the same error.

We need solution to this problem.

Hi everyone

I just tested that Arduino IDE 2.1.0 can be run and used together. You can try it in the following ways:

Reinstall the arduino ide and run it again
Check the error message ‘This system lists some UTF-8 supporting locales that you can pick from.’ You know it’s a coding problem so you need to do a few steps (it worked on my computer)
Add the following two lines to.bash_profile – set the encoding:
❀open .bash_profile
❀export LC_ALL=en_US.utf-8
export LANG=en_US.utf-8
❀To have the Settings take effect, run source.bash_profile,
❀After exiting PyCharm, open the project again

If you solve your problem, you might give a like and let more people see it

Hi, thanks for your advise - unfortunately it didn’t help:
exports

If you see something like this error:

Traceback (most recent call last): ... RuntimeError: Click will abort further execution because Python 3 was configured to use ASCII as encoding for the environment. Either switch to Python 2 or consult http://click.pocoo.org/python3/ for mitigation steps.

You’re dealing with an environment where Python 3 thinks you’re limited to ASCII data. The solutions to these problems vary depending on the locale of the running computer.

For example, if you have a German Linux computer, you can solve this problem by exporting your locale to de_DE.utf-8:

export LC_ALL=de_DE.utf-8 export LANG=de_DE.utf-8

If you are using a US machine, en_US.utf-8 is the preferred encoding. On some newer Linux systems, you can also try using C.UTF-8 as the locale:

export LC_ALL=C.UTF-8 export LANG=C.UTF-8
In short,You will need to change different encoding Settings depending on your computer.

As I wrote before - I’m running MacOS not Linux.
I also run have this:

23-07-23 12:50 ~ % env | grep LC_
LC_TERMINAL_VERSION=3.4.19
LC_CTYPE=UTF-8
LC_TERMINAL=iTerm2
LC_ALL=en_US.UTF-8
23-07-23 12:50 ~ % env | grep LANG
LANG=en_US.UTF-8

so I don’t understand why I cannot run the simplest test program:

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(1000);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(1000);                      // wait for a second
}

I also wrote before that:
the problem in the same environment doesn’t occur for XIAO ESP32 C3
see:

int led = D10;

void setup() {
  // initialize digital pin led as an output
  pinMode(led, OUTPUT);
}

void loop() {
  digitalWrite(led, HIGH);   // turn the LED on 
  delay(3000);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED off
  delay(3000);
}

and in case of ES32C3 it works

Another question is:
why in case of XIAO nRF52840 Sense “click/core.py” is used and in case of XIAO ESP32C3: "esptool.py’

OK - I can see, that ESP32C3 is based on another MCU but still I don’t know how to deal with the error for XIAO nRF52840 Sense
