The integration of the Data Acquisition, Offline Processing and Hardware Controls using MQTT has been proposed for the STAR Experiment at Brookhaven National Laboratory. Since the majority of the Control System for the STAR Experiment uses EPICS, this created the need to develop a way to bridge MQTT and Channel Access bidirectionally. Using CAFE C++ Channel Access library from PSI/SLS, we were able to develop such a MQTT-Channel Access bridge fairly easily. The prototype development for MQTT-Channel Access bridge is discussed here.
