Totally new and lost. ESP32 dev bd on OSX

[freddietheone]

Hello Forum,

Completely new and out of my depth here.
I have an ESP32 dev board with USB connection. I'm trying to erase it and flash MicroPython into it.
Basic guidance says to do this I should install esptool using 'pip install esptool' from Terminal. However, when I try this I get the error message:

% pip install esptool
Collecting esptool
Could not fetch URL https://pypi.python.org/simple/esptool/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) - skipping
Could not find a version that satisfies the requirement esptool (from versions: )
No matching distribution found for esptool

I can expand this out, if that helps?

This has left me 'stuck' as I know so little I do not know how to proceed. Hence, I call up knowledge acquired by those way ahead of me.

I'm running a MacBookPro, Catalina 10.15.6 and Python 3.8.4 (which I am just starting to learn). I am after loading MicroPython to the ESP32 board, to do simple remote monitoring of a wind-turbine, where a physical connection would be almost impossible.

Sadly I fell at the first hurdle!

All help and guidance gratefully received, up here in cloudy York.

Regards,

Hello,
I think, a very simple way to flash and use micropython in ESP32 board is to use Thonny. (www.Thonny.org) it works very well on MacOs.
esptools are included
In the menu you have [execute / choose the interpreter and then at the bottom you can chose the microsoftware you want to flash to the board.
...
And everything is going simple and easy

Sounds like you have a very old version of pip.

How did you install Python?

Hello jimmy,

Thanks for your reply... contact and help at last.

I simply went to 'https://www.python.org/downloads/' and downloaded the latest version for OSX, which was 3.8.4. Ran the install and copied it to Applications. Prior to this I had the Apple loaded V2.7 and a V3.2 loaded by me a while ago and never really used.
Work, work and more work, got in the way. No time to learn and play.

What do you have in mind?

VKR,
