Hello,

I’m working on performance evaluation of CoAP so i want to edit some CoAP parameters (ACK_TIMEOUT, MAX_RETRANSMIT, NSTART etc.)

i found these parameters in 2 files :

\californium-master\californium-core\src\main\java\org\eclipse\californium\core\network\config\NetworkConfigDefaults.java and

\californium-master\californium-proxy\src\main\java\org\eclipse\californium\proxy\ProxyProperties.java

I realized that there’s no effect of changes on ProxyProperties.java file, so i tried editing NetworkConfigDefaults.java file. But when i change MAX_RETRANSMIT to another value other than 4, maven gives me errors.

I attached the error dump. How can i change these CoAP parameters ?

Thank you.
