Hey David,

 

Thanks for the response. Actually what I’ve done is gone into the server/security c files in the client example and hardcoded an additional instance of each. In doing so I was able to create an additional server connection and connected two servers to a single client(2 terminal windows running ./lwm2mserver and 1 running ./lwm2mclient). And so when disconnecting a server from the client, I can no longer reconnect to that same local UDP port. When I disconnect a server using either ^C or q and try to reconnect, I get “failed sending (x) bytes, missing connection”.

Hi,

 

First note that LwM2M use a different terminology than REST protocols. In LwM2M, the end-device is named the Client and the managing entity is named the Server. Even if the end-device is the one presenting resources to be manipulated by the managing entity.

 

So if I understand correctly your use-case, you have two LwM2M Clients registering to a LwM2M Server. How do you “disconnect” the Client from the Server ?

It looks like you killed the LwM2M Server and the LwM2M Client registration update messages get no response.

 

Regards,

David Navarro

Hey folks,

 

So currently I have two servers connected to a single client. And whenever I disconnect a server from the client and try to reconnect a server to the same connection(i.e. “5683”), It fails. I ran both list/update server on the client side and got the “registration update pending” status when I disconnected a server and then the “registration failed” status after calling update. Is there a way to update a single server connection to reconnect with a server or a way to go through the server registration process again? Any help or tips would be greatly appreciated!
