Not able to start CAN communicaton

[197Fabian]

Hello,

I am stuck with the following problem. The complication of the software has worked for me without problems, also the retrieval of data from the Daly BMS Works for me. However, when running the software, the ESP always hangs at the following command: sendCanTXFrame(XXXXX);

The first three commands run through but then the following function no longer works:

ESP32Can.CANWriteFrame(&tx_frame);

Can someone help me here?
