Problem using the AVR IoT Cellular with the Arduino IDE

[vonrle]

Hello everyone,

some days ago I bought an AVR IoT Cellular board and tried to do some examples with it. Sadly it did not work out as I hoped. As soon as I try to upload any code, I get the following exception:
java.lang.NullPointerException
at cc.arduino.packages.uploaders.SerialUploader.uploadUsingProgrammer(SerialUploader.java:314)
at cc.arduino.packages.uploaders.SerialUploader.uploadUsingPreferences(SerialUploader.java:89)
at cc.arduino.UploaderUtils.upload(UploaderUtils.java:78)
at processing.app.SketchController.upload(SketchController.java:713)
at processing.app.SketchController.exportApplet(SketchController.java:686)
at processing.app.Editor$DefaultExportHandler.run(Editor.java:2149)
at java.lang.Thread.run(Thread.java:745)

I followed all the steps suggested on this website: https://iot.microchip.com/docs/arduino/start
I never had this with another board. Does anyone have a suggestion on what I can do to fix that problem?

Thank you so much!

Hello,

Which programmer option are you using? Have you followed the steps under "Step 3: Configuring the IDE" here: https://iot.microchip.com/docs/arduino/introduction/devenv#step-3-configuring-the-arduino-ide? Are you using Arduino IDE 1 or 2?

Hello,

thank you so much for your answer! I did not fully complete everything in step three. Now it should work. :)
