[Firmware Update][Blockwise] - Is it possible transfer a firmware more than 300MB using Blockwise?

[mathns28]

Hello, I'm newer in lwm2m and I'm learning, so if I miss something forgive me.

I made a file transfer using the CaliforniumServerEndpointsProvider as base. I changed the RootResource for other implementation that controls the files.

The class I get from here: https://github.com/eclipse-leshan/leshan/issues/70#issuecomment-2047006480

I tested locally and It works pretty well, but when I tested on the server I get every time a delay:

logPart.txt

This occurs randomly, sometimes after about 20 transmissions, sometimes after 500 transmissions.

The server configuration that I'm using is here. This is in default mode, I only changed the MAX_RESOURCE_BODY_SIZE, PREFERRED_BLOCK_SIZE and MAX_RETRANSMIT, because the files are more than 300Mb.

config.txt

I don't know where is the error, if I lost something, if I need to increase some value on the configs, or decrise, if I can get more logs to validate the message...

I would be grateful if someone could help me!!
