How to run microPython in ESP-WROOM-32 module

If you have an ESP-WROOM-32 module, you can use Zerynth Studio to upload your microPython code.
You can download it from https://downloads.zerynth.com/zerynth.tar.xz

See the following video to do it


Probably you could have the following issue after click the uplink icon:

[error] Can't open serial: /dev/ttyUSB0

To fix this error it is enough to change the permissions of access to the terminal:

sudo chmod 666 /dev/ttyUSB0

Another issue is when you try to upload the code and you get the following error:

[error] No answer to probe

To fix it, you must virtualize your device.

After to do that, you could upload your code and get the following output:

info] Probe sent
[info] Got header: r2.1.2 SxTxJKbAQFaaRCayjua5sw esp32_devkitc 42504c29f107 ZERYNTH
