Setup
Platform: EVSE
Firmware Version: i.e. V02_01_00
Host Controller Interface: Ethernet
Host: FreeV2G (EV_v2.1.0.1)
FreeV2G <-- ETH --> Whitebeet <-- PLC --> Development Board <-- CANCase --> Diagnostic Tool
Describe the issue
We are trying to establish the Slac communication between Codico board and development board. We have initiated the Slac process from our side (EV) and the Codico (EVSE) is responsive until the last step, when we are expecting to get CM_SLAC_MATCH.CNF.
The number of retries for CM_SLAC_MATCH.REQ is 4, that means, the EV sent for 5 times REQ.
We changed the one of your Python script as we saw that for the connection we need to have 8V on the CP+PE, but when we measured them we only had 0.43V, so now the Voltage check is ignored
Steps to reproduce
The development board is up and running. The FW is downloaded to QCA (EV side).
After these preconditions are completed we start the FreeV2G, first we use the activate.bat script from the cmd, and we use the following command:
python Application.py eth -i "Ethernet 3" -m c4:93:00:48:af:f9 -r EVSE -p
When the message "Start SLAC matching" is showing, the SLAC process from EV is triggered.
Everything is going fine until the last message from EVSE.
Expected behavior
SLAC matching successful
Current status
SLAC matching timed out
EVSE loop finished
Goodbye!

Question
Do you see any mistake made by us?
The MAC address set in CM_SLAC_MATCH.REQ was wrong!
The SLAC process is working!
