RE: How to set node permanently as Leader/Router?

Hi Jørgen,

Thank you for the answering, it works!

I increased the leader weight by passing weight = 200 (default = 64) to otThreadSetLocalLeaderWeight() and

called otThreadBecomeLeader() whenever its role changes to not leader simultaneous. The node takes Leader role back from another node.

Hi,

Every partition requires one leader in order to function properly. The first router that starts the network will always become the leader. This is by design, to make sure the network is self-healing, in case the leader stops working, or the network is split into more than one partition.

You can try to promote the node that you want to have the leader-role by calling otThreadBecomeLeader(). You may also try to increase the leader weight by calling otThreadSetLocalLeaderWeight() to make it more probable that that node becomes the leader when partitions merge.

Best regards,
Jørgen
