How to set baud rate for serial link using AT-commands? - danford - 08-21-2024
I want to use the vLinker FS USB to listen to OBD2 messages on a Ford Transit Connect 2010. This works, but I get a buffer full situation.
I am looking for information on how to increase the transfer speed between the vLinker FS and the PC. The default speed seems to 115200.
I have tried the AT BRD command, but it does not seem to be supported.
How can I configure the vLinker FS to use a higher speed for the data flow towards the PC? Is there some AT-command that can be used? I know Forscan can increase the baud rate above 115200, so I am sure there is a way to do this. How is it done?
Here are more details on my setup:
I am using Linux and for testing I am using the minicom terminal emulator for sending AT commands.
After configuring the vLinker FS using these commands, I use the AT MA command to start listening. I receive around 480 messages before the vLinker FS reports "BUFFER FULL" and exits the monitor mode.
AT Z # Reset
AT D # Default
AT SP 6 # Set Protocol
AT CFC1 # Flowcontrol
AT D1 # Show DLC
AT AL # Allow long messages
AT H1 # Show headers
AT CAF0 # Disable Formatting
AT L0 # Disable linefeeds
AT S0 # Remove whitespace
The above commands are taken from here:

After sending the AT MA command, I receive around 480 messages and then this happens:
