consult about bluetooth in esp32 of newbie in micropython

[jummiGz]

I'm using a Lolin S2 Mini board with the latest version of micropython, v1.20.
I want to learn how to use the bluetooth on this board, but I am not able to get any of the examples in the documentation to work.

All the examples ask to load either a bluetooth or ubluetooth library, but none of them are available in the version I'm using.

Could you clarify how I can use, in a simple way, the bluetooth of my device?

Some example?

I haven't work with Lolin S2 Min but it is based on esp32-s2 so You can try start from Nordic UART Service example at beginning.
Since it is BLE then Serial Bluetooth terminal app for android is excellent for start.
For windows/ mac os sometimes a dongle is needed (depends from laptop/pc type) and then using python (for example bleak lib) more complicated examples can be mage.

Yes, the information that indicates I had already seen.
The steps that I do to be able to work with this example are the following:

1 .- I download the file main.py
2.- I save it in the esp32
3.- restart

The error that you give me is:
Traceback (most recent call last):
File "", line 3, in
ImportError: no module named 'ubluetooth'

In line 3 I see that it is : import ubluetooth

And that's where I can't move forward, since I can't find where I can download those libraries.

Try load another firmware version , for example MicroPython v1.19.1.

edit: I check manifest file for your board, and propably ble is not available ( verison C3 has BLE but S2 not)

I thought so, but since I'm a newbie I wasn't sure.

I have tried version 1.19 and 1.18 and neither of them works. The example, it seems, is for version 1.14, but for espS2 there is no version below 1.18, so I can't test it.

Versions 1.18, 1.19 and 1.20 don't work with the example you gave me.

I have done double check -> unfortunately there is a matter of board version, micropython for s2 board version do not support bluetooth ( you can check board.json . Also in description in wendors , there is no info abaut suporting BT , only Wi-fi.

Thank you for taking the time to help me.
Thank you so much.

I hope they will be able to support this board soon.
All the best.
