BG96 and LwM2M - Is there any example that currently works?

IoT Modules LPWA Module

I’m using this example as a working base:

http://www.noomio.com.au/wiki/bg96/lwm2m-step-by-step/

After rebooting the modem I get the expected log:

LWM2M: State: STATE_REGISTER_REQUIRED
LWM2M: State: STATE_REGISTERING
LWM2M: State: STATE_READY

I have an entry on the Leshan server for this device, but when I select the “read” button for any property on the Leshan server, it has a device timeout in the first attempt and after that, it says the device is sleeping:

“Unable to read instance /1/1 for urn:imei:866425030054276 : 400 Invalid request:The destination client is sleeping, request cannot be sent.”

My device is running FW BG96MAR04A04M1G_01.005.01.005

Any idea of what could be the problem? Are there more updated examples to use?

Thanks in advance.

Best regards

Fernando

Hi Stephen,

Thanks for your feedback! I am currently seeing these messages on the debug console, doesn’t this mean the device is registered on the server?

LWM2M: State: STATE_REGISTER_REQUIRED
LWM2M: State: STATE_REGISTERING
LWM2M: State: STATE_READY

Or do I need to register it manually? And how is this done?

Best regards

Fernando

I’m facing the same problem.

The device is registered with the lwm2m server as I can see the registration ID on the server.

Here are the logs from the debug console from the BG96.

Net: Net Registered
dss_netapp: DSS_NetApp Registered
atfwd_cli_app: Atfwd_Cli_App Registered
LWM2M_EXT: LWM2M_EXT Registered

Command List:
  Commands:
     1. Help
     2. Exit

  Subgroups:
     3. Net
     4. dss_netapp
     5. atfwd_cli_app
     6. LWM2M_EXT


>
LWM2M: CLI registered
LWM2M: LWM2M_LOG:Carrier type = 0
LWM2M:
LWM2M: REG EP NAME = 4
LWM2M:
LWM2M: BOOTSTRAP EP NAME = 4
LWM2M:

Any help would be appreciated.
