Thank u for your answer.

But what is the proper way to use tcp_write() and tcp_output()? Where can I use them?

Would it be correct to do:

 

LOCK_TCPIP_CORE();

tcp_write();

tcp_output();

UNLOCK_TCPIP_CORE();

 

If I do so, how can I ensure, that I can still receiving data? Don’t I block the RX side?

Sorry, I am a noob but how can I ensure that I am in the tcpip thread?

Sounds like you are calling lwIP functions from another thread than the lwIP thread, in your case the CAN thread.
