In VSCode how do you set the -b parameter when esptool.py is called to set the baud rate?
It defaults to 115200 which is rather slow and I can't see where to change it.
How do you set the flashing baud rate in Visual Studio Code?
Re: How do you set the flashing baud rate in Visual Studio Code?
Don't worry, this is an easy fix... on VSC go to the bottom left corner settings gear icon (the bigger icon, not the one on the bottom bar), it will open a tab for settings. On the top search bar, "Search Settings" you can search baud then you'll be graced with Idf: Baud Rate where you can change this setting here.
Re: How do you set the flashing baud rate in Visual Studio Code?
Thanks but unfortunately that doesn't work.
In the configuration the only options for "baud" are "idf.py monitor baud rate" and "UART console baud rate".
If I change the idf.py monitor baud rate it flashes at 115200 but then switches to the higher rate for the monitor. The UART console baud rate has no effect.

Hi,
With this command
idf.py
See this parameter :
-b, --baud INTEGER Baud rate for flashing. This option can be used at most once either globally, or for one subcommand.

Re: How do you set the flashing baud rate in Visual Studio Code?
I noticed this in the tasks.json file:
So it's using the same for both flashing and monitoring. First thing would be to separate those two so that you don't have to run the monitor at the same speed as the flasher.
What's strange is that the config option affects the monitor baud rate but not the flasher baud rate... Unless it does affect the flasher and it's just that you can't flash faster than you can at 115200 baud due to the bootloader being slow or something. Maybe I can get a scope on there to see what the actual rate is.
Code: Select all
"command": "${config:idf.pythonBinPath} ${config:idf.espIdfPath}/tools/idf.py -p ${config:idf.port} -b ${config:idf.baudRate} flash",
"command": "${config:idf.pythonBinPath} ${config:idf.espIdfPath}/tools/idf.py -p ${config:idf.port} -b ${config:idf.baudRate} monitor",
Code: Select all
config:idf.baudRate
