Hi,

The module was not able to make Airvantage connection due to failure of LWM2M\_DM\_PSK\_IDENTITY(LWM2M credentials is missing for your module ).

This credentials needs to be provided SierraWireless .And this Credential Need to be generated based on your module FSN

A sample Key will be look like  
AT+WAMS=1,9,268,1,0
