I have searched a bit an can’t find clarification. I want to develop my own Arduino CAN BUS reader for the EMU Black, but I am curious if the EDL-1 will stream CAN BUS data over bluetooth. Is this possible? ---

The EDL-1 receives serial data but its more or less the same information as the EMU stream. it’s not customizable if that’s what you mean. If you want that then your best route is via CAN. ---

Sorta. I don’t want to customize the EMU stream, I just want to be able to tap into the stream using the EDL-1. Also, I have looked again, and I can’t find any details about the CAN BUS stream . Is this published somewhere? ---

yes the CAN bus stream is published in the Black’s software help files. I don’t know if the serial version is published anywhere though… ---

Where did you find that? There’s 3 Ecumaster serial protocols, one is generic and 2 are for EDL-1 of different firmware versions. ---

This is EMU Black OBD2 CAN data stream. ---

I went to, V3, the “CAN Setup” menu and hit the help icon on the popup and then scrolled down. How do I find the serial protocols? I am running V3 and want to program my arduino to read the CAN and filter out specific things that I want to display.
