13.1.14.1. Provides¶
main:slac
SLAC interface implementation.
config:
device:
description:Ethernet device used for PLC.
type:string
default:eth1
evse_id:
description:EVSE id - 17 octets.
type:string
default:PIONIX_SAYS_HELLO
nid:
description:NID (Network Identification Key) - 7 octets.
type:string
default:pionix!
number_of_sounds:
description:SLAC number of sounds.
type:integer
ac_mode_five_percent:
description:Use 5% mode in AC (true). Set to false for DC. The only difference is the handling of retries.
type:boolean
set_key_timeout_ms:
description:Timeout for CM_SET_KEY.REQ. Default works for QCA7000/QCA7005/CG5317.
type:integer
sounding_attenuation_adjustment:
description:Offset in dB that should be added to the calculated sounding attenuation
type:integer
publish_mac_on_match_cnf:
description:Publish the EV MAC address on the token_provider interface when matching is confirmed (CM_SLAC_MATCH.CNF). This can be used for autocharge as an alternative to the EVCCID derived from HLC and published by EvseManager. This can be used for AC autocharge on cars that do not support actual HLC on AC.
type:boolean
publish_mac_on_first_parm_req:
description:Publish the EV MAC address when the first CM_SLAC_PARM.REQ. This should not be used as it is quite error prone: The MAC address might be from another car via cross talk. It is better to wait for the matching to be done.
type:boolean
do_chip_reset:
description:Perform a chip reset after setting NMK using the RS_DEV.REQ Vendor MME Extension (Only works on Qualcomm chips)
type:boolean
chip_reset_delay_ms:
description:Delay between SET_KEY.CNF and RS_DEV.REQ
type:integer
chip_reset_timeout_ms:
description:Timeout for RS_DEV.REQ (waiting for RS_DEV.CNF)
type:integer
link_status_detection:
description:After matching.cnf, wait for link to come up before sending out d_link_ready=connected using LINK_STATUS Vendor MME Extension (Works on Qualcomm and Lumissil chips)
type:boolean
link_status_retry_ms:
description:Delay between retries of LINK_STATUS requests after matching request
type:integer
link_status_timeout_ms:
description:Timeout for Link to come up after matching request
type:integer
debug_simulate_failed_matching:
description:Only for debugging. Simulate failed matching by sending a wrong NMK to the EV.
type:boolean
config:

default: 500
Timeout for RS_DEV.REQ (waiting for RS_DEV.CNF)
link_status_detection:boolean <optional>
default: False
After matching.cnf, wait for link to come up before sending out d_link_ready=connected using LINK_STATUS Vendor MME Extension (Works on Qualcomm and Lumissil chips)
