[EKari.1]

Hi everyone,

I have a stm32f746 discovery board and I want to configure a snmp agent on it. I followed a simple example and wrote a code. In my code, I want to send a constant value in snmp protocol when i call its OID. I test my code using "Paessler SNMP Tester".when i reset the board, in the first time all things is ok and constant value receive using SNMP tester. but after that, my code is not work and even ping request answer timeout. "main.c" attached to post.
