# Since 20/06/2021, the default OpenThread config (and therefore also the default border router

# presence of the network periodically on all channels in the active dataset's channel mask, but
# has the consequence of making the router switch away from the active channel for a bit. If you
# have sleepy end devices connected to the router, these may end up going to a detached state if
# they attempt a data poll when the parent has switched away to announce on another channel.
# To avoid this, set the channel mask for the border router such that only the configured channel
# is allowed. This avoids the issue with the announce feature, but will prevent channel hopping
# from taking place (which would be a very advanced use-case versus having sleepy devices in the
# network).
