How to unbind？

[liisa]

When my mtd device is connected to a thread network, what should I do if I want to untie and join another thread network? How should I untie and clear the network information of the previous thread network?

Hello,

Yes, you can try the factoryreset API:

otInstanceFactoryReset()

https://openthread.io/reference/group/api-instance#otinstancefactoryreset

That should delete the network information, and you can start the provision process again after that.

Best regards,

Hello,

By the way, how do I tell the thread network that I am leaving before the end device leaves the Thread network?

You don't need to leave the network. Pretty much like a WiFi network, the device will be automatically removed after a certain time period. (also, I couldn't find any API doing this). 

Please see my colleagues reply here:
