Session stopped event right after sending Start Charging. #311

Closed vsCodeGB closed 6 months ago

vsCodeGB commented 6 months ago

Platform: EVSE Firmware Version: V02_01_00 Host Controller Interface: SPI Host: Own Implementation

Describe the bug: I get Session stopped event right after sending Start Charging command. When I send command "C0 27 6E 0E 00 00" I get stop event. It is tested with DIN+ISO modes, DIN mode only. Same situation with QCA7005 FW v3.0 and v1.1.0-02. I use SPI for communication and charging to Ethernet will be complicated, maybe I send wrong command? Python demo works perfect with this EV, but ends at pre charging, also EV charging from another station. EV support DIN only.

From the debug log I cannot see anything strange happening that would lead to the issue described by you.

Am I reading correctly that when you use the FreeV2G python application it also stops at pre charging?

To help you with the issue I kindly ask to provide a wireshark trace. How to do so is explained in this guide.

If you activate port mirror this will also work when your host controller is connected via SPI. The traffic on the PLC will be mirrored to the ethernet interface when port mirror is activated.
