It helped a lot to parse the log into WireShark

Re: QCA7000 Foccci+Clara User thread

I also had unsuccessful charging attempts that "broke down" when exchanging slac data. I assume that this may be related (similarly to UDP exchange) to the re-sending of packets from the station. I will continue to explore, I will share the results

Re: QCA7000 Foccci+Clara User thread

By the way, not only the Schneider charging station in the "isLightBulbDemo=1" mode, but also some others begin to compensate for the lack of load by increasing the voltage. But not all such stations go into the "OverVoltage" state at the same time

Re: QCA7000 Foccci+Clara User thread

Victory! Analyzing the data exchange, I found the problem of the Clara state machine. After sending the " PowerDeliveryReq " package, the " PreChargeRes " package arrived from the station (there were repeated shipments of the " PreChargeRes " package). At the same time, the state machine was in the ...

Re: QCA7000 Foccci+Clara User thread

Into the piggy bank of knowledge. From the data exchange sniff of the charging station with the BMW i3: at the "Precharge" stage, a current of 0A is requested. At the charging stage, the current is requested gradually, with an increase of 1.5-2 A per packet

Re: QCA7000 Foccci+Clara User thread

Maybe it will lead to some thoughts on correcting the code.
Tests with a real battery.
After "PreCharge" we get "[EVSEStatusCode: EVSE Emergency Shutdown (5)]" in the "PowerDeliveryResponce" package.

no, I tried separately and with a load of 8 kW and separately with a real battery.

Re: QCA7000 Foccci+Clara User thread

Hello all!
Does anyone have the opportunity to test Foccci+Clara on a Schneider EVlink CCS charging station? Or do you already have experience charging at this charging station?
If I set isLightBulbDemo==1 , I get the error "0x85 OverVoltage" on the station screen, while in the log I see a voltage ...

Re: Develop a QCA7000 board?

Hello everyone.
Tell me, I'm faced with the following not very good situation. When connecting the board to the charger, at the moment the QCA wakes up, there is some kind of surge on the line (or CP or CE) on the side of the charger, such that the controller is reset. Maybe someone has encountered ...
