Hi @urish I noticed errors like https://github.com/espressif/pytest-embedded/actions/runs/22448984330/job/65011684261#step:6:12904 since wokwi-client 0.4.0 released.

  /usr/local/lib/python3.14/site-packages/wokwi_client/transport.py:140: RuntimeWarning: Background recv error: Server error 1: Firmware file pytest.bin appears to contain source code, not compiled firmware. See: https://docs.wokwi.com/vscode/migrating

This PR is to fix the upload. PTAL, thanks.

@hfudev and was the .bin file actually a compiled firmware file? or something like flasher_args.json?

firmware_path = Path(flasher_args).as_posix()

I think it's path to the flasher_args.json

[urish]

But you are calling upload_idf_firmware(), so it should handle that for you: https://github.com/wokwi/wokwi-python-client/blob/419d9d45cac33e464fc6f082b98768f90f2fbebb/src/wokwi_client/idf.py#L36

Do you still get this error when using upload_idf_firmware()?

[hfudev]

@urish after the first try, I got different errors. Now I understand the problem better.

arduino and idf has different layout. arduino firmware_path points to the .bin file, and idf firmware_path points to the flasher_args.json.

The tests passed locally. PTAL 6dbc86c. Thank you.

Added two comments for the commit:

1. passing flash size to start_simulation (i.e. self.client.start_simulation(firmware.firmware, elf='pytest.elf', flash_size=firmware.flash_size))
2. The "Starting simulation..." message is actually printed after simulation has already started (cosmetic)
