Pelion Device Management SDK for Python

The mbed-cloud-sdk gives developers access to Pelion Device Management API using Python.

Note

Pelion Device Management was previously known as Mbed Cloud, some references (such as the package name) remain for technical reasons, but the two names should be considered equivalent.

Prerequisites

Python 2.7.10+ / Python 3.4.3, built with SSL support.

Use of virtual environments or pipenv is recommended to manage python versions and dependencies.

Installation

pip install mbed-cloud-sdk

Usage

These instructions can also be found in the official documentation:

  1. Create a configuration file .env in your $HOME or project directory, and add your API key from the portal:

    MBED_CLOUD_SDK_API_KEY="your_api_key_here"
    
  2. Import the library and you’re ready to go.

    from mbed_cloud.foundation import Device
    
    # List the first 10 devices on your Pelion Device Management account.
    for device in Device().list(max_results=10):
        print("Hello device %s" % device.name)
    

Documentation and examples

The SDK guide and examples are available at GitHub.

The documentation contains many examples covering various Use Cases that you may have. In each case you can compare the python implementation with alternatives in languages supported by the other Pelion Device Management SDKs.

Contributing

The Pelion Device Management SDK for Python is open source and we would like your help; there is a brief guide on how to get started in CONTRIBUTING.md.

Licence

Versioning

The current version scheme used by the SDK follows PEP440:

<SDK major>.<SDK minor>.<SDK patch>

Troubleshooting

Suggestions for issues that have been reported when using the SDK.

  • SSL version / SSLV3_ALERT_HANDSHAKE_FAILURE
    urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='api.mbedcloud.com', port=443):
    Max retries exceeded with url: /v3/firmware-images/
    (Caused by SSLError(SSLError(1, u'[SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:590)'),))
    

    This probably means the Python interpreter being used has an old version of SSL. The recommended minimum version for the SDK is 1.0.2, however security best practice is to use the latest available version of SSL, which can be found here: https://www.openssl.org. It is recommended to upgrade/rebuild the Python interpreter with the latest available SSL library. The SSL version currently in use by the Python interpreter can be found using python -c "import ssl; print(ssl.OPENSSL_VERSION)"
