no module named 'ble_advertising'

[Thanatos]

Hello

When following the steps in the introduction to ESP32 and MicroPython, I was able to erase my original firmware and flash new firmware on it.
However, when trying to use the `advertising_payload` like so:

Code: Select all

from ble_advertising import advertising_payload

I receive this output:

Code: Select all

I have an Espressif ESP32_DevKitc_V4 and I tried literally every firmware version on this page, as well as even a TinyPICO version (which gives the same result as well as an additional error).

Output of `CTRL-D`:

Code: Select all

MPY: soft reboot

What am I doing wrong here?

You must upload that file (found on the github examples) to the board.

Something like: ampy -p /dev/ttyUSB0 put ble_advertising.py

Your port may vary.

Thanks, that solved my problem. Two questions however:

1. Is this step documented somewhere?
2. Why is this essential file located in the examples folder?

Thanks!
