Hi John,
There are several ways to read the assetData from the device - one of them is the “Observe / Notification”. This is a mechanism through which the device can notify changes in asset to the server (device push). This mechanism is currently NOT supported in Legato.
So, the user has to initiate data retrieval from the Server. i.e A read has to be initiated from AVMS,
Refer to doc.airvantage.net/av/howto/har … sset-data/ - Retrieving data from Device.
The above mechanism is a simple REST Api query to AVMS Server. The server in turn sends a lwm2m read operation to retrieve the data from the device.
Thanks,
Prush
