Trouble uploading to RedBoard Artemis Nano

Development Boards Artemis

I’m currently using a Mac running Big Sur and when I try to upload the BLE LED example (with the latest board definitions and ArduinoBLE libray) I get the following error:

[24036] Failed to execute script asb

I’ve been trying to debug this for the longest time and can’t seem to have any success. Any help would be appreciated.

Exampel8 BLE-LED, as it was available in the earlier version of Sparkfun library ( up to version 1.1.0) is NOT compatible with ArduinoBLE. It will not work, Try callbackled.ino in ArduinBLE peripheral examples.

The problem has nothing to do with the compilation process since it compiles just fine––rather it’s a problem with uploading and the serial port in particular from what I can garner from the error message. I’ve tried this on two different laptops running Big Sur with both encountering the same issue. Since this seems to be endemic with Macs running the latest version, I’d really appreciate some help from Sparkfun in getting this board to work.

you are correct… my bad.

Looking on github https://github.com/pyserial/pyserial/bl … rts_osx.py, it states that

kIOMasterPortDefault is no longer exported in BigSur but no biggie, using NULL works just the same

It is a known issue for Sparkfun : https://github.com/sparkfun/Arduino_Apollo3/issues/299. While there is solution/patch in the list_ports_osx.py it is not used as Sparkfun is using a compiled version of the uploader.

Not sure what they are doing about it… Maybe you can try to run the python source from 2.0.3/tools/uploaders/asb with the right parameters or make a new compiled version with pyinstaller.
