I'm trying to transmit messages through CAN using HAL library. For test I repeated code from the first part of this video I have the same bluepill so I just did the same. Also I've tried his project, but changing Nucleo RE to ZE model. I've looked through other sources and they all do the same thing, and in their videos/articles bus perfoms as it is supposed to.
But on all of my devices
HAL_CAN_AddTxMessageproduces empty (or maybe error) message
Debugging showed me nothing wrong: function returns "HAL_OK". I went step by step through this function in debug mode and everything seemed as normal. But niether loopback nor normal mode transmitts correct message.
Also I've checked my LA with MCP2515 + TJA1040 and CAN bus worked as it has to
P.S. Also in loopback mode interrupt doesn't happen as well as in normal mode and data frames are empty too
