AH Sniffer firmware upload issue

[tx4342]

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:
txw8301_v2.4.1.3-40938_2026.3.5_TAIXIN_WNB.bin
Chip ID:4002
Version:2.4.1.3-40938

Upload not OK:
project_v0.0.0.1-17652_2022.9.15_ AH Sniffer.bin
Chip ID:4002
Version:1-17652

Could you help me resolve this issue?
Thank you!

是因为sniffer固件，要通过串口升级（at+fwupg），不能通过ota升级到网桥；

具体的方法：

升级后，可以恢复出厂：
