Expected completion time of this lab: 15 min.

  • Create the following flow
     

  • After a few seconds, you receive both an "oap" notifications and a "notifData" notification. These correspond to the same information: the manager publishes the (raw) "notifData" notification, the JsonServer then understands that this is an OAP notfication and parses that.

  • In the "notifData" notification, find fields.data field. First, copy-paste the bytes from that field "value received" column below. Second, use the SmartMesh IP Tools Guide (http://www.linear.com/docs/42453), Section 9 “On-Chip Application Protocol” to interpret those bytes and fill in the "explanation" column.
