- pev(1) Qualcomm Atheros Open Powerline Toolkit pev(1)
- NAME
- pev - Qualcomm Atheros Plug-in Electric Vehicle Emulator
- SYNOPSIS
- pev [options]
- DESCRIPTION
- Emulate the PEV part of the HomePlug AV Signal Level Attentuation Characterization (SLAC) protocol where a PEV is a
- "Plug-in Electric Vehicle" and an EVSE is an "Electric Vehicle Supply Equipment" or charging station. This program will
- remain active until it detects and connects to an available EVSE-HLE on the powerline network. Once connected, it
- charges a virtual vehicle for about 10 seconds then disconnects and terminates. See the HomePlug Green PHY Specification
- Release Version 1.1 for more information on this protocol.
- Signal Level Attenuation Characterization (SLAC) enables a station to measure the signal level of its transmission at
- other stations in the network. It is designed for automotive applications where there are multiple plug-in vehicle
- (PEVs) and electric vehicle supply equipment (EVSE) on the network. The PEV signal level is measured at multiple EVSEs
- to determine which EVSE the PEV is actually plugged into. The process leading to this determination is called "Green PHY
- PEV-EVSE Association" (GreenPPEA).
- This program is part of the Qualcomm Atheros Powerline Toolkit. See the plc man page for an overview and installation
- instructions.
- OPTIONS
- -c Print the PEV-HLE configuration profile on stdout. The configuration profile specifies program defaults in a for‐
- mat that you, as a user, can edit and save. Use options -p and -s to read named profiles and sections.
- -d Print the contents of the PEV-HLE session variable on stdout. The session variable is an program data structure
- that stores information passed between the PEV-HLE and EVSE-HLE during SLAC association. This option is used to
- inspect and veriify information relevant to the process. If the program was compiled with variable SLAC_DEBUG
- defined then this option also prints MME message fields before messages are sent or after they are received.
- Interested parties can follow along in the source code.
- -i Select the host Ethernet interface. All requests are sent via this host interface and only reponses received via
- this host interface are recognized. The default interface is eth1 because most people use eth0 as their principle
- network connection; however, if environment string "PLC" is defined then it takes precedence over the default
- interface. This option then takes precedence over either default.
- -p profile
- The PEV-HLE configuration profile name. The program will supply default values for missing profile elements. See
- the example profile shown below. The default profile name is "pev.ini".
- -q Enter quiet mode. Progress messages are suppressed.
- -s section
- The configuration profile section name. The program will supply default values for missing configuration profile
- elements. See the example profile shown below. The default section name is "default".
- -v Enter verbose mode. All Etherenet frames sent or received by the program are displayed on stdout.
- -?, --help
- Print program help summary on stdout. This option takes precedence over other options on the command line.
- -!, --version
- Print program version information on stdout. This option takes precedence over other options on the command line.
- Use this option when sending screen dumps to Atheros Technical Support so that they know exactly which version of
- the Linux Toolkit you are using.
- PROFILES
- The default configuration profile for this program is "pev.ini". The default profile section is "default". Users may
- create addition profiles and reference them with option -p or add additional sections to an existing profiles and refer‐
- ence them with option -s.
- Attenuation Theshold
- The average attenuation above which the PEV will not connect to an EVSE. The default value is 10db.
- MSound Pause
- The time in milliseconds between each MSound sent by the PEV-HLE to the EVSE-HLE. Sending MSounds too frequently
- overloads the EVSE-PLC. Sending them too infrequently wastes time. This value is derived and does not appear in
- the HPGP specification. The default pause is 10 milliseconds.
- Vehicle Identifier
- Vehicle identification. The 17-byte Vehicle Identification Number to be placed in CM_MNBC_SOUND.IND.SenderID.
- This value is not used but is can be changed here so that the field is easy to spot within network message traces.
- Network Membership Key
- The 16-byte Network Memberhip Key (NMK) for the PEV-PLC device. This program uses CM_SET_KEY to sets the PEV-PLC
- NMK to this value after disconnecting. The default value is the key for Network Password "HomePlugAV".
- Network Identifier
- The 7-byte Network Identifier (NID) for the PEV-PLC device. This program uses CM_SET_KEY to sets the PEV-PLC NID
- to this value after disconnecting. The default value is the same as that for Network Password "HomePlugAV".
- REFERENCES
- See the Qualcomm Atheros AR7420, QCA6410 IEEE 1901, HomePlug AV and QCA7000 HomePlug Green PHY PLC Chipset Programmer''s
- Guide or the HomePlug Green PHY Specification Release Version 1.1 for more information on this protocol.
- EXAMPLES
- The following example starts a PEV session on interface eth0 and wait up to 2000 milliseconds (or 2 seconds) for the EVSE
- to respond during any given exchange.
- # pev -ieth0 -w2000
- The default PEV-HLE configuration profile, "pev.ini", looks something like this but it can be changed using a normal text
- editor. Use option -P to produce a template profile, if one is needed.
