<![CDATA[AH Sniffer firmware upload issue]]>Hello!

I'm trying to upload sniffer firmware with OTA tool v 1.0.9 and getting this message:

Other firmware uploads successfully.

Upload OK:

Chip ID:4002
Version:2.4.1.3-40938

Upload not OK:
project_v0.0.0.1-17652_2022.9.15_ AH Sniffer.bin

Could you help me resolve this issue?
Thank you!
