Hi, I connected my tbeam to pc with data usb cable I was following tutorial and when I type esptool chip_id in gitbash it respond with bash: esptool: command not found, what can I do to fix it?
Generally means that the software in question, in this case esptool is not installed. What do you get from running esptool -h (displays help from most command line programs if they are installed properly)
Thank you for fast answer, this is what I get $ esptool -h
bash: esptool: command not found
But I run command pip install --upgrade esptool before.
When you ran pip install --upgrade esptool where there any messages/output?

Often there is a path or alias set by the install that is not recognized until you re-open the command prompt, try closing git bash and re-opening it and try it again

It is strange, it worked for a while I even managed to set wifi on the device, and now it is not working again.This is the message:

That is pretty strange.
I bet the problem is that the special directory pip puts ‘wrapper scripts’ into is not in your path. When you install python there is a checkbox in the GUI installer to turn this on.
@Nidzolino123 Did you resolve the esptool install problem? I seem to be having similar trouble with the esptool chip_id or esptools.py chip_id
Welcome!
What OS are you running? I just ran into this problem on linux (specifically ubuntu). I fixed it, but I am not saying I did it in the best way…I mostly don’t know what I am doing.
I installed esptool with:
pip3 install --upgrade esptool
after that running esptool or esptool.py just said command not found. so I added the install path to my $PATH. If you run the same pip3 install --upgrade esptool again it told me esptool.py was at:
/home/USERNAME/.local/lib/python3.9/site-packages
so I edited my .bashrc
nano ~/.bashrc
and added this to the very bottom of the file:
export PATH="/home/USERNAME/.local/lib/python3.9/site-packages:$PATH"
then I need to login and back out for the settings to take effect OR just enter:
source ~/.bashrc
now I can run esptool.py with no problems. anyway hope that helps someone. also if this a totaly insane way to fix the problem, please someone correct me. lol

But still getting nothing with esptool.py chip_id

Make sure that you use a proper USB cable with data lines and not those cheap cables that only support charging. Also, confirm that your device shows up as serial adaptor.
