The LWM2M objects enable client to collect statistical information and enables the LWM2M Server to retrieve these information, set the collection duration and reset the statistical parameters. The following resources are listed:

Resources Description
Mobile originated SMS

Indicates the total number of Mobile originated SMS for the current LWM2M communication session
Mobile Terminated SMS Indicate the total number of Mobile Terminated SMS (successfully received by the device)during the collection period.
Received data Indicate the total amount of data received during the collection period.
Transmitted data Indicate the total amount of data transmitted during the collection period.

It enables bi-directional File transfer between the device and the deviceWISE Cloud.

File Upload:

File Upload is to upload a file from the device to the deviceWISE (dw) IoT Platform. To upload a file,

  1. Click Upload
    File transfer upload dialog appears
  2. Provide the full path of the file to be uploaded
  3. Do one of the following:
    1. If the file needs to be Global, check the Global check-box. When Global is selected, the file gets uploaded to the Files that is accessible across the deviceWISE (dw) IoT Platform.
    2. If the file needs to be local and associated to the Thing, then do not check the Global check-box. If the Global check-box is not selected, the files gets uploaded to Files.
  4. Click Submit. If the Global is not checked, then the file appears in the Files.

File Download

File Download is to download a file from the deviceWISE (dw) IoT Platform to the device. To download a file,

  1. Click Download
    File transfer download dialog appears
  2. Click File repository and select
    1. Thing: if the file is associated to the Thing.
    2. Global: if the file is in the Global Files location.
  3. Select the file you want to download to the device.
  4. Enter the File path in the device where you want the file to get saved.
  5. Click Submit.

Click Wakeup to instantiate wakeup command. The Wakeup sends an SMS to the client. If the client is in the power saving mode (Sleep) then it bring it to the normal mode. To remotely force the device to connect to the network and register to deviceWISE Cloud, the SMS feature is used to send an SMS to wakeup the device. This is done by navigating to either the LWM2M or LWM2M Device Management Tab and click the Wakeup button. You can then select the type of SMS to send. It is possible to view the status of the SMS in the LWM2M tab on the right hand side to determine if the SMS was delivered successfully

Click the Refresh button to refresh all the resource values and get updated with the current values.

The error log contains the latest 5 errors with the data/time information of when the error occurred.
