Local Profile Assistant for Device (LPAd) - LPAd SM-DP+ Connector

This project offers an implementation of the SGP22 Local Profile Assistant for Device (LPAd).

Allows communication with the SM-DP+ and implements the needed logic of ES9+ (LPA -- SMDP+) interface. It is also implemented all the logic for ES10x (LPA -- eUICC) interface. It is implemented in Java.

LPAd Truphone Projects

The current project is only one part of several other Truphone’s* projects that implement LPAd totally. The following diagram gives an overview of currently existing projects that relate to Truphone*’s* LPAd *implementation:

High level explanation of the several Truphone’s LPAd projects:

• LPAd React-Native - UI for List Profiles, Download a Profile and Enable/Disable/Delete a Profile. It is implemented in React-Native.

• LPAd React-Native/Android Bridge - Allows React-Native sub-project code to communicate with LPAd Android sub-project code. This implementation is specific for React-Native and Android/Java.

• LPAd Android - Allows communication (through Android TelephonyManager) with the installed eUICC on the Device. It is also the Proxy to LPAd RSP Connector sub-project. Implemented in Android/Java

• LPAd SM-DP+ Connector - This project. Allows communication with the SM-DP+ and implements the needed logic of ES9+ (LPA -- SMDP+) interface. It is also implemented all the logic for ES10x (LPA -- eUICC) interface. It is implemented in Java.
