Hi Mamo,

The log message indicates, that Scandium’s DTLS server has received a DTLS record from a client of an unknown type. Such records are ignored by Scandium but indicate that your client is sending non-compliant records. Are you sure that your client is configured to use DTLS for securing the connection to the client? I am asking because the client might be configured to use plain CoAP (no DTLS) and thus send CoAP requests to a secure endpoint on the server …

Regards,

Kai

Hello all,

 

I have a small set up to test Leshan with a CoAP client node in an IPv6 network (6LoWPAN). In doing so I get a warning message, I don't know if this warning is also a critical error though. My small setup isn't functioning either because of this (or another) problem. I can see a registration request from the client is received at the server side but then no response it sent back.

 

The warning seems to be coming from Californuim. This is the log:

 

WARNING: Received illegal record content type: 64

Thanks

Best regards,

Mamo
