Decoder missing on armhf

[maretodoric]

Describe the bug
Starting TheengsGatewaay on armhf platform ends with an error stated below.

File "/usr/local/lib/python3.9/runpy.py", line 188, in _run_module_as_main
    mod_name, mod_spec, code = _get_module_details(mod_name, _Error)
  File "/usr/local/lib/python3.9/runpy.py", line 147, in _get_module_details
    return _get_module_details(pkg_main_name, error)
  File "/usr/local/lib/python3.9/runpy.py", line 111, in _get_module_details
    __import__(pkg_name)
  File "/opt/venv/lib/python3.9/site-packages/TheengsGateway/__init__.py", line 26, in <module>
    from .ble_gateway import run
  File "/opt/venv/lib/python3.9/site-packages/TheengsGateway/ble_gateway.py", line 35, in <module>
    from ._decoder import decodeBLE, getProperties, getAttribute
ModuleNotFoundError: No module named 'TheengsGateway._decoder'

File exists as filename _decoder.cpython-39-arm-linux-gnueabihf.so but somehow fails to load it.

Replicated on RPi3B+ and RPi 1 B+.
Have any ideas?

To Reproduce
Steps to reproduce the behavior:

1. Start gateway with predefined json

{
    "host": ”192.168.0.200”
    "pass": "",
    "user": "",
    "port": 1883,
    "publish_topic": "home/TheengsGateway/BTtoMQTT",
    "subscribe_topic": "home/TheengsGateway/commands",
    "publish_all": true,
    "ble_scan_time": 60,
    "ble_time_between_scans": 60,
    "log_level": "DEBUG",
    "discovery": true,
    "discovery_topic": "homeassistant/sensor",
    "discovery_device_name": "TheengsGateway",
    "discovery_filter": "[IBEACON,GAEN,MS-CDP]",
    "scanning_mode": "active",
    "adapter": "hci0"
}

Expected behavior
It shouldn't crash

Screenshots

Environment (please complete the following information):

• version used: V0.5.0
• Context of your project

Additional context
This is inside docker image. Seems to fail even though multiple images (for different platforms) were built the same way. Also. Tested on two different devices, leads to same issue.

• You should not have a compilation error if you use the versions of the libraries linked into the libraries folder, this badges show you the state of the compilation
  
• If you are not sure this is a bug or an enhancement post your question to the forum

Hello,

Do you have the same error with v0.4.0 ?

[maretodoric]

Haven't checked honestly, but tried it now and yes. Same error, only on armv6.
However do keep in mind that this was all built inside docker image. But still, seems to work fine with armv7, arm64 (and x86 platforms ofcourse) but apparently not armv6.

Not sure how to approach this issue.

Also, when i went into lib folder where TheengsGateway is installed, i tried importing _decoder manually, it failed

However on armv7, works fine

Honestly extremely strange.

I'm seeing the same thing on latest docker image.

Is this still happening with decoder now being built and distributed as a separate Python package on PyPI?
