Hello,
These are the formats for Marshalled Sensor Data given in the Mesh Specification freely downloadable from :
https://www.bluetooth.com/specifications/mesh-specifications/ . Mesh Model Specification 1.0.1 Section : 4.2.14 , Page 120.
Client(Smartphone in this case) sends the getSensor command with the null property Id or the Property Id of the Sensor and get the Data in the Sensor Status.
Android App knows the property id of the Sensors supported already .Otherwise it should invoke 4.2.1 Sensor Descriptor Get command to get the currently supported sensors(coming in future release).
