CAN-BUS Shield get no data displayed

Projects General Guidance

Hello, I need some help.

I am using the CAN-BUS Shield v1.0 with the Arduino Uno R3.
Uploaded the receive_check (GitHub - Seeed-Studio/Seeed_Arduino_CAN: Seeed Arduino CAN-BUS library - MCP2518FD&MCP2515&MCP2551) example of the library and connected the shield with the cars CAN-H and CAN-L.

The Rx LED ist blinking, but i dont get any information on the serial monitor. CAN BUS Shield init ok! and the rest of the debug messages will be displayed.
The correct BUS Speed is selected.

I also tested this library (GitHub - coryjfowler/MCP_CAN_lib: MCP_CAN Library), but same problem.

connected to bmw k-can 100KBPS: blinking but no data on serial monitor
connected to bmw pt-can 500KBPS: same here

Thanks in advance! Best regards from Germany.
Stefan

I have been trying to hack the canbus of a elevator controller and have had the exact same results..

Rx flickers but there is no data coming in. Have you guys been able to resolve this issue??

I have even tried new Can bus shields and tried cutting the track above CANH and CANL but no progress?

Aren't we using the same components?
the board: www.ebay.com/itm/131336753696
the shield: www.elecfreaks.com/estore/can-bus-shield.html
Any updates? I seem to be experiencing the same behavior. :frowning:

Same Board and Shield Yes. I have had no response from any of the Can-Bus sniffing I have attempted. Still trying to crack it though.
