Abstract
The disclosed subject matter includes techniques for performing a channel availability check. A method includes initiating, via a processor of a master device, a first connection on a first wireless channel with a subordinate device and transmitting, via the processor, a beacon to the subordinate device. The method includes monitoring, via the processor, the first wireless channel for a first predetermined amount of time for a connection request from the subordinate device in response to the beacon. The method includes performing the channel availability check to detect energy profiles on a second wireless channel for a second predetermined amount of time after the first predetermined amount of time. The processor may cycle between transmitting the beacon and monitoring the first wireless channel and performing the channel availability check on the second wireless channel until a threshold time is exceeded, the connection request is detected, or an energy profile is detected.
