ESP32 stucks on OBD2.begin()

[carlosmellado]

I'm trying to use this library with an MCP2515 and an ESP32.
Code compiles properly but when calling to OBD2.begin(); the process stucks and I don't get any response.

Does anyone knows how to solve this?

Thanks!

Seems like the problem is on the CAN library when using the CAN.extendedPacket
On the PR sandeepmistry/arduino-CAN#117 seems like it's fixed but still not working on my side.

Okay, seems like this library only works with arduino + MCP2515 or ESP32 + SN65HVD230, and I was trying with ESP32 + MCP2515.
Now I tried with arduino mega + MCP2515 and it worked fine but I'm not able to make it work with an ESP32 + SN65HVD230 even using the same code.
Now it's not stuck on OBD2.begin() but this function is returning always false.

Can any of you help me in make it work on the ESP32 please...?

Thanks!

can you share your schematic between OBD2, mcp2515 , arduino mega that works?
Thanks you
