How to use Restoring Function

[XPAWAN]

I have started wpantund and add prefix to the network.
After wpantund restart I can see restoring logs "Restoring interface/user originated address/prefix/route entries on NCP" but the prefix is not restored.
How to use this feature correctly?

Hi,
Can you please help provide more details about the commands you used to add the prefix?
Thanks

Hi,
I was using following commands

	wpanctl leave
	sleep 1

	wpanctl reset
	sleep 2

	wpanctl setprop Network:Key --data "00112233445566778899AABBCCDDEEFF"
	wpanctl setprop Network:PANID 0xABCD
	wpanctl setprop Network:XPANID DEAD00BEEF00CAFE
	wpanctl setprop NCP:Channel 11
	wpanctl setprop Network:Name NordicOpenThread
	wpanctl setprop Network:PSKc E00F739803E92CB42DAA7CCE1D2A394D
	wpanctl attach

When switching to "associated" state I was adding a new prefix with command:

	wpanctl config-gateway -d fd11:22::

When this operation is done I am restarting wpantund and expecting that after seeing log
"Restoring interface/user originated address/prefix/route entries on NCP" this prefix is restored, but its not.

Thanks @XPAWAN

How are you restating wpantund? Note that wpantund does use RAM variable to save prefixes/addresses/routes, etc... and not a non-volatile memory. If you restart the wpantund process itself, it starts fresh.
