Method, apparatus, and computer program product embodiments are disclosed to improve the channel switching in communication protocols, by simplifying transmission of only a single, acknowledged switching message to trigger off channel—or base channel switching after an initial off channel configuration and set-up of the direct link. The single message off channel switching indication in direct link is based on two specific timeout timers that serve as a basis for channel switching between the devices in TDLS direct link. An immediate fallback transition is provided to the base channel in the event that the communication in the off-channel does not succeed. The timeouts in the fallback procedure allow continuing the planned data transfer immediately in the base channel of the TDLS direct link if the switching to the off channel has not succeeded.
