Yes, if you want to set the channel manually. The thread cli example uses the otLinkSetChannel function to set a default channel for a thread network.

Hi Charlie

If I call function "otchannelmanagersetautochannelselectionenabled", can I control the channel from switching automatically?

Best regards,

Hi winik,

Yes, the channel switch is handled by Channel Manager APIs. It tends to choose a clear channel and avoide crowded channels to prevent potential interference.

In most of the cases, the openThread stack will handle all the networking layers operation, you only need to focus on your application layer development.

The re-powered thread device will join the same network depending on the configuration,

Best regards,

Charlie
