//| The `_bleio` module provides necessary low-level functionality for communicating
|
|

|
|
//| for internal use by libraries but not by the end user. Its API may change incompatibly
|
|
//| between minor versions of CircuitPython.
|
|
//| Please use the

//| `adafruit_ble <https://circuitpython.readthedocs.io/projects/ble/en/latest/>`_
|
|
//| CircuitPython library instead, which builds on `_bleio`, and
