I am trying to use TLS on my application but I have problem. I used mbedTLS on my Server side ( on stm32) and I used python-tls (GitHub - arthurazs/python-tls: Simple TLS connection example) client.py application. But I have a result as shown below
Where is my problem I couldnt find anything server send Server Hello but some retransmission message occurs. Why this happenned ? How can I detect the problem ?
MbenTLS side is server, server send 150 byte data for the Server Hello. But in the Server Hello message details gives me:
This is my debug output:, where is my problem I dont find. Why the packet lenght :576 but sending message 136 ?
