# Open issues

## Issue16: First CurrentDemandReq is rejected with FAILED_SequenceError and EVSE_Shutdown
- observed on Alpitronics HPC with version v0.4-6-g257e5af
- log 2022-12-20_alpi_currentDemandSequenceErrorShutdown.pcapng
- same result in two trys

## Issue15: After end of PreCharging, the log says "re-initializing fsmPev"
- observed with v0.4 on the Compleo charger
- PreCharge target voltage is reached. The fsmPev sends a message
01fe800100000012809a022189cbf75b9625a9513022800a0800
and after one second the state machine seems to run into timeout.


# Closed issues

## [Solved] Issue14: Connection loss after authorization
- with version v0.4.
- same version works fine on Compleo
- could be also caused by weak power of the powerbank. The TpLink and Dieter made restart from time to time.
- to be retested with better supply and on other chargers.
- Test pass with v0.4-6-g257e5af, with the Intenso two-cell powerbank.

## [Solved] Issue12: Alpi reports "sequence error" for CableCheck
- with version v0.3.
- maybe he expects the state C, or something is wrong with the sequence before.
- Test pass with v0.4-6-g257e5af

## [Solved] Issue13: Compleo SLAC stops after SlacParamResponse
- Root cause: The Compleo ignores the StartAttenChar, if the timeout field is set to 1000ms instead of the nominal 600ms.
- Solution: implemented the nominal 600ms.
- fixed with commit cf9160c1bcb9c0760b7f67bb8a36f03c9fe9c9a1
- Test pass on Compleo with v0.4

## [Solved] Issue10: Alpi says SequenceError in ChargeParameterDiscoveryRes
- ServicePaymentSelectionRes says "ResponseCode": "OK", and has no more fields.
- Afterwards we send ChargeParameterDiscoveryReq and get ChargeParameterDiscoveryRes containing "ResponseCode": "FAILED_SequenceError".
- Analysis: In the ISO case, the ChargeParameterDiscoveryReq comes after the AuthorizationRes with EVSEProcessing=Finished. But we are using DIN, and here there is no AuthorizationRes, but ContractAuthentication instead. But, this does not
have a field EVSEProcessing. And in DIN, we have dinContractAuthenticationResType, which contains ResponseCode and EVSEProcessing (see OpenV2G, dinEXIDatatypes.h).
- Solution: Send ContractAuthenticationReq after ServicePaymentSelectionRes, and repeat it until it says "finished". Test pass with v0.3.

## [Solved] Issue11: TCP connection fails on Alpi
- Observation: On Alpitronics, the SDP works, but the TCP connect fails. The connection is rejected by the charger.
- Root cause: We used fixed port 15118 for the TCP. This is not intended, even it works on other chargers (ABB).
- Solution: use the TCP port, which was announced in the SDP response.
- Test pass with version v0.2-9-ga9b6e82.
