Carelink Python Client

Experimental Medtronic CareLink Client in Python

Python library, which can be used for retrieving data from Medtronic CareLink of online CGM and insulin pump device data uploads (Guardian Connect, MiniMed 7xxG) inside and outside of US.

This is a port of the Java library CareLinkJavaClient

Status

This is a developer version. Works for me. Extensive testing of different use cases is needed. Please report back if it works also or you.

Supported devices

• Medtronic Guardian Connect CGM (to be confirmed)

• Medtronic MiniMed 770G pump (to be confirmed)

• Medtronic MiniMed 780G pump

Features
