How can we read the live CAN BUS data from CAN OBD2 - ISO 15765-4 can bus data reading using Arduino

Ref.: iso 15765-4 arduino - Google Search

Your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advice on) your project :wink: See About the Installation & Troubleshooting category.

Thank you for the response. ELM 327 and STN21X are good option for read the CAN data.

I am looking for the CAN bus data reading from (any) Vehicle using Arduino chipsets
Waiting for suggestions and advises

Note that the ELM327 can handle communication over multiple protocols, not just CAN:

    Protocol - Description
    0 - Automatic
    1 - SAE J1850 PWM (41.6 kbaud)
    2 - SAE J1850 PWM (10.4 kbaud)
    4 - ISO 9141-2 (5 baud init)
    5 - ISO 14230-4 KWP (5 baud init)
    6 - ISO 14230-4 KWP (fast init)
    7 - ISO 15765-4 CAN (11 bit ID, 500 kbaud)
    8 - ISO 15765-4 CAN (29 bit ID, 500 kbaud)
    9 - ISO 15765-4 CAN (11 bit ID, 250 kbaud)
    A - ISO 15765-4 CAN (29 bit ID, 250 kbaud)
    B - User1 CAN (11* bit ID, 125* kbaud)
    C - User2 CAN (11* bit ID, 50* kbaud)

Since Installation and Troubleshooting is such a popular alternative to "Project Guidance", I wonder if I should start monitoring it - never have in the past - in order to answer such problems earlier, before they are moved. :thinking:

Is Arduino can read data from ELM 327?
How to communicate Arduino with ELM327?
