Arduino Uno and MCP2515 module to read CAN BUS data and transmit the data over bluetooth

Projects General Guidance

Hi, I am stuck with this.

I’m using a 48V 200A lithium-ion battery with CAN-BUS data output.
I am trying to use Arduino Uno and the MCP2515 module to read data from the CAN BUS.

I have tried searching the internet, but all I found were examples using Arduino and MCP2515 to read data from vehicles over OBD-II. But mine is a round 8-pin.

The other end has CAN H and CAN L, which I could use to read off data by using CANalyst-2, but when I connect these CAN H and CAN L cables over to the MCP2515 CAN H and CAN L ports, I receive no data at all.

I hope there’s someone here who can enlighten me, or perhaps this cannot be done.

Alternatively, if there is a small and inexpensive CANBUS analyzer with Bluetooth functionality, please share it with me.

Essentially, the project aims to extract CAN-BUS data from my lithium-ion battery and transmit it to my mobile phone via Bluetooth.

A photo of the pins might help, it sounds like maybe male OBDII

I have a couple, just search Amazon.

Post your code along with an annotated schematic showing exactly how you wired the system. Note any wire lengths over 10"/25cm. Post links to technical information on the hardware, the UNO we have, the MCP2515 maybe not there are several.
