timeout error when read CC2652 Sonoff dongle

[kyc1338]

I tried to save the firmware of the Sonoff zigbee dongle P and used this command "python -m zigpy_znp.tools.nvram_read COM8 -o nvram_backup.json" in two different PC and a MacBook but have the same error below :

Traceback (most recent call last):
File "C:\Users\xxxxx\AppData\Local\Programs\Python\Python311\Lib\site-packages\zigpy_znp\api.py", line 673, in _skip_bootloader

^^^^^^^^^^^^^^^^^^^^^

During handling of the above exception, another exception occurred:

Please advise any solution to this issue.

I am guessing that this now works with a newer release of zigpy-znp as previous releases was not fully updated for Python 3.11

Regardless, suggest that you try using zigpy-cli instead -> https://github.com/zigpy/zigpy-cli

See zigpy-cli README.md file -> https://github.com/zigpy/zigpy-cli/blob/dev/README.md#network-commands
