Hi @rccess,

Have you had a chance to check the logs of your OCPP backend system? It looks like the backend has blocked the idTag. From that point on, the EVSE cannot start a transaction. In SteVe, that's most often due to a previous transaction which still counts as active and therefore occupies the idTag. You can probably delete obsolete transactions by hand in the backend (in SteVe, you can for sure).

The debug messages here are not too helpful here, admittedly. From f925f1b on, the library also prints the reason for the denial of the idTag.

Hello @matth-x

There is another issue at the moment

"stack": "Error: OCPP Command 'RemoteStartTransaction' has failed

  "error": "Error: Timeout after 10 secs for Message ID 'f3b713f4-a655-4886-8b36-cdae54e57b78' with content '[2,\"f3b713f4-a655-4886-8b36-cdae54e57b78\",\"RemoteStartTransaction\",{\"connectorId\":1,\"idTag\":\"KH1675768958\"}] (app)

other charging station starting with same idTag

Please do advise

RemoteStartTransaction is available when you configure it with

https://github.com/matth-x/ArduinoOcpp/blob/e742bc760950731309c9c9ce1e4391a69ac2da82/src/ArduinoOcpp.h#L91

Inside the callback, you must decide whether to actually start a transaction (e.g. you might not if no cable is plugged) and call startTransaction() if yes.

i have disable that line but still same issue

from microocpp.

Oh that line must remain in ArduinoOcpp.h.

You can implement RemoteStartTransaction like that:

https://github.com/matth-x/ArduinoOcpp/blob/e742bc760950731309c9c9ce1e4391a69ac2da82/examples/SECC/main.cpp#L273-L280

from microocpp.

i have defined setOnRemoteStartTransactionSendConf and setOnRemoteStopTransactionSendConf in setup

But issue is still same,

Transaction got rejected with error

from microocpp.

My guess is that the BootNotification has never succeeded in the latest run. Without the BootNotification, the EVSE remains silent and doesn't react on RemoteStartTransactions. Can you maybe roll back the changes to the code in the first post above (there it worked).

If you add the following lines to platformio.ini and post the full debug output, the problem will become much more apparent:

https://github.com/matth-x/ArduinoOcpp/blob/e742bc760950731309c9c9ce1e4391a69ac2da82/platformio.ini#L21-L23

from microocpp.

BootNotification is calling in lastest version

can you please advise on the same

Thanks in advance !
