• AT Commands for Baud Rates???
  • AT Commands for Baud Rates???

    tjshadyluver > 09-18-2024, 05:01 AM

    I'm developing my own application and I got it working great with HS-CAN on pins 6 and 14 with "AT SP 6" but my next task is SWCAN or GMLAN for GM and MSCAN for Ford. I've been searching like crazy how to setup the vLinker to be able to talk to 33.3kbps on pin 1. There has to be an AT or ST command to send to make that work. Also MSCAN on many Ford Modules. Some are 125k 250k and 500k baud but on pins 3 and 11. I'm only able to talk to 500k HSCAN. Any PM or Ideas would greatly appreciated!

    It sounds like you’re working with a vLinker device and trying to configure it for SWCAN (GMLAN) and MSCAN on non-standard pins. While HS-CAN on pins 6 and 14 is straightforward, SWCAN (single-wire CAN at 33.3kbps) and MSCAN (on pins 3 and 11) require special configurations.
    SWCAN (GMLAN on Pin 1 - 33.3kbps)
    For single-wire CAN (SWCAN) on pin 1, vLinker devices typically support it but require explicit mode switching. Try the following:

    Code:
    AT SP 8
    This may be necessary to activate SWCAN communication. Some devices also require additional settings like
    Code:
    AT SW 01
    for normal operation.
    Multi-speed CAN (MSCAN) is less commonly supported on basic ELM-based adapters. However, vLinker devices often have a way to remap pins and adjust baud rates.
