"busy p..." appearing in passthrough mode binary data

[tjaffey]

When downloading large binary files in passthrough mode (https://github.com/espressif/esp-at/blo ... s.rst#L159) I am sometimes seeing the data stream being corrupted with the bytes:

0d0a 6275 7379 2070 2e2e 2e0d 0a
"\r\nbusy p...\r\n"

When this occurs, my microcontroller is not sending any data to the ESP32, it is only receiving the binary stream.

Tested with the latest version on github, revision a2b8ca9

How can this output be disabled? as it's indistinguishable from the real data I am expecting.

This issue is soon going to impact our product deadlines. We have purchased several thousand ESP32C3 devices. Is there some way we can escalate this issue?

Thank you.

`busy p...` means that The system is in process of handling the previous command, thus CANNOT accept the new input.
It shouldn't happen if last command process is over.

Could you please enable the ESP-AT logs to see what happened?
