The Plugfest takes place September 30 - October 2, 2018 and provides an opportunity to test and demonstrate device and system interoperability and resolve compatibility issues. Implementers are invited and encouraged to cooperate with others to demonstrate system-wide clock synchronization and operation of protocols across as wide a spectrum of devices as possible.
