Hi, I have installed the sample app LWM2MControl. All installs OK and then I start the application and the trace is as follows. What could I have missed? I have an AirVantage account and have registered this device on it. Edited I should have added I am running 16.10.1.m3 (effectively 16.10.3) on a FX30s and my AirVantage account is on the EU servers. Thanks, Karl ``` Nov 7 08:28:04 | Legato | INFO | supervisor[523]/supervisor T=main | app.c app_Stop() 2731 | Stopping app 'lwm2mControl' Nov 7 08:28:04 | Legato | INFO | supervisor[523]/supervisor T=main | apps.c DeactivateAppContainer() 340 | Application 'lwm2mControl' has stopped.

Digging a bit more and trying to connect using the AT commands, resulted in AT+WDSG +WDSG:0,2 +WDSG:1,0 The first response (when checking the AT reference pdf) indicated > 2—AirVantage Management Services must be provisioned. A bootstrap session is > required. What is the bootstrap session referred to, and how to I provide it? ---

A little more information from trace… This is still not working.

Ok, so I have it working although not entirely sure why. In AirVantage I deleted the device and added it again, selecting a FW at this point as opposed to adding it later on. That seems to have made the difference? Not sure why. And yes I did have the correct IMEI and serial numbers…
