A system and method of processing information regarding medical devices in wireless communication with each other is provided in which a controller device has a first wireless communication link with a first medical device, such as an analyte sensor, and a second wireless communication link with a second medical device, such as a delivery device. A processor in the controller device monitors the status of the first and second wireless links and upon noting a degradation of either one, compares the first wireless link status with the second wireless link status and provides guidance for resolving a communication problem based on the comparison. The latency of the communicating medical devices is considered.
