Correct procedure for changing baud rate?


#1

What is the correct procedure for changing the target baud rate in Dev Studio?


#2

Depends on if your target is in production mode, or development mode.
Global procedure:

  • send AT+IPR=;&W to the target
  • Required in development mode only: reset the target (AT+CFUN=1); Note that in production mode, target changes baud rate immediately after the OK answer, while in development mode, it will switch baud rate only after target reset
  • close the port
  • change baud rate on DS side
  • re-open the port

Didn’t realise that bit.

Anyhow, it’s a lot of faff; request for the next wish-list: something simpler!

Yes, I’m adding a wish-list item for a GUI control in DS to change baud rate (both on PC and target side) in one click.

Excellent!

:smiley:

Would also be good to have the current settings visible; eg, as Hyperterminal does in its Status bar…

I guess we could add some columns for that in the Devices view, with maybe some customization capabilities (too many columns = need of a HD display to show comfortably all of the information… :confused: )
