# 2. You installed the python library pyshark, according to https://github.com/KimiNewt/pyshark/

# pip install pyshark
|

# 3. You cloned and compiled the OpenV2Gx EXI decoder from https://github.com/uhi22/OpenV2Gx
|

#
|
||||
# Limitations:
|
||||
# - Only DIN is supported at the moment.
|
||||
# - The script treats all V2G EXI messages as DIN messages. This means, the ApplHandshake messages at
|
||||
# the begin of the charging session will lead to wrong or not decoded data.
|
||||
# - The path where the script look for pcap files needs to be configured in the code.
|
||||
#
|
||||
# Possible improvements / Todos:
|
||||
# - Show also the SLAC, NeigborDiscovery and SDP.
|
||||
# - Add flexibility to also decode the ApplHandshake messages.
|
||||
# - Add ISO support.
|
||||
# - Configure the path where to look for pcap files via command line
