aioble: AttributeError: 'module' object has no attribute 'Service' (and - no instructions, and lack of useful examples)
It is not clear from this page:-
https://github.com/micropython/micropython-lib/tree/master/micropython/bluetooth/aioble#passive-scan-for-nearby-devices-for-5-seconds-observer
how to use any of that code
>>> import l2cap_file_server
Traceback (most recent call last):

we need to be told what to do to make it work, and there needs to be working examples to show the features - especially the "scan" - and the examples need to tell you what you need to to do run them.
even the multitests don't seem to work? (and there's no tests for the scan feature):
MicroPython v1.21.0 on 2023-10-06; Generic ESP32 module with OTA with ESP32
Type "help()" for more information.

I tried to run the examples/bluetooth/ble_temperature.py and it failed with

According to the ESP-IDF[https://github.com/espressif/esp-idf/blob/dd8db6621b930a9cbfeef14a0d4daba8c8506e74/components/bt/host/bluedroid/api/include/api/esp_gatt_defs.h#L295] it needs to be 0x20
I had the problem when I try to use aioble compiled in as a module in MicroPython. When I install aioble with mpi on the board itself, everything works.
@gitcnd Does installing the module with mip solve the problem, as suggested by @fpetzold ?
Installing the module with mip solve the problem also for me.
thank's @fpetzold
