There are three different use cases, where this project can be helpful:
1. Sniffing the traffic between an CCS charger and a car. For instance to measure which side is the limiting element for reduced charging power.
2. Building a charger for CCS or for AC with digital communication.
3. Building a charging unit for a car which does not support powerline communication.
In this project, we call this mode *ListenMode*.
2. Building a charger for CCS or for AC with digital communication. We call this *EvseMode*.
3. Building a charging unit for a car which does not support powerline communication. Let's call it *PevMode*.

## List of open topics
- add listener to socket at port 15118 (use case: evse)
- add evaluation of the TP packets (use case: sniffer)
- convert the EXI data to the readable xml (e.g. using https://github.com/FlUxIuS/V2Gdecoder, or https://github.com/Martin-P/OpenV2G)
- replace the fix-configured addresses (MAC, IP) in the python script by the real one from the operating system
- improve docu (add layer diagram, improve hardware docu, add link to evse which provides the 5% PWM)
## Biggest Challenges
- [ListenMode] Find a way to enable the sniffer mode or monitor mode in the AR7420. Seems to be not included in the public qca/open-plc-utils.
Without this mode, we see only the broadcase messages, not the TCP / UDP traffic between the EVSE and the PEV. Any idea how to enable full-transparency
of the QCA?
- [all modes] convert the EXI data to the readable xml (e.g. using https://github.com/FlUxIuS/V2Gdecoder, or https://github.com/Martin-P/OpenV2G).
Evaluate different EXI decoders/encoders, regarding speed, correctness and stability.
- [all modes] replace the fix-configured addresses (MAC, IP) in the python script by the real one from the operating system
