Logs

With OmniCore, you can specify a log topic to send log events from devices connected. There are two types of logging: ERROR and INFO. ERROR logging captures device communication errors, while INFO logging captures general information about communication from devices. Both the log topic and type can be configured at the registry level.

• deviceId
