I had a similar report earlier for data above 100 MiB, yet this probably depends just on the block size. I opened a bug in Eclipse’s Bugzilla:

Could you please add a stacktrace as a comment?

 

I will try to eventually find some time next week to go ahead with debugging and fixing.

 

Thanks for the report

Subject: [cf-dev] CoAP error while writing large LWM2M Object

 

Hello Everyone,

I am using Leshan LWM2M server for client server communication. It internally uses Californium CoAP server. I am seeing an error while writing a String resource with 1 MB of data.

 

During the send operation of resource from Server to Client, I see a given below error error. This is 100% reproducible.

ACK-5.00   MID=15578, Token=9233882e, OptionSet={"Block1":12358}, ""

This response is handled in method BlockwiseLayer::receiveResponse()

Below is the code snippet of method where the response is handled.
 else if (!response.getOptions().hasBlock2()) {
                // All request block have been acknowledged and we receive a piggy-backed
                // response that needs no blockwise transfer. Thus, deliver it.
                super.receiveResponse(exchange, response);
            } else {

Can someone help me to resolve this issue?

 

Thanks,

Mrinal
