[leshan-dev] Problem with keeping communication

[Rarsonic Mato Sunyer <pdvr@xxxxxxx>]

I have a program that uses a Leshan client object, running from a Raspberry Pi 1. Said program uses DTLS security.

The issue is that many times, after an indefinite amount of time, the client stops sending or accepting packets, thus failing the LWM2M updates and not receiving any requests from the server.

If I stop the client then start it again the connection works once more, at least until the next failure.

That has happened too on PCs but it's much rarer.

This may be a Californium or even an unrelated issue, but I'm starting here, Leshan being on top of the networking API pile.

Best Regards,

Ramon Mato.
