Abstract
In one aspect, an example method includes monitoring, by a hub station, a first channel activity level associated with a first channel of a plurality of channels within a particular frequency range. The hub station communicates with a low-energy device using the first channel. The method includes determining that the first channel activity level satisfies a threshold activity level and switching to a second channel of the plurality of channels to communicate with the low-energy device. The method includes notifying the low-energy device that the hub station switched to the second channel by sending an acknowledgement message to the low-energy device on the second channel in response to receiving a message from the low-energy device on the second channel. The message is sent to the hub station on the second channel after at least one unsuccessful attempt to send the message to the hub station on the first channel.
