Indeed, no data seems to have been received. Do you have a log that shows what really happens on the bus?

[kirya-dev]

It seems no support for ID29 bits

Im started PR https://github.com/pylessard/python-udsoncan/pull/181

[pylessard]

Thanks, How do I know when this PR is ready?

[kirya-dev]

I will report logs.

But right now new problems detected! Didnt support:

• Transmission of a Multi-Frame Request Message
• Reception of a Multi-Frame Response Message

Steps for reproduce:

print(client.get_supported_dtc().service_data.dtcs)

in application - no response in Time. and in logs:

PassThruWriteMsgs(1, [{ISO15765; RxStatus: 0; TxFlags: ISO15765_FRAME_PAD | CAN_29BIT_ID; TS: 00:00:00; LEN: 6; ExtraIndex: 0; Data: 18-DA-B0-F1-19-0A}], 1=>1, 1000) -> STATUS_NOERROR
PassThruReadMsgs(1, [], 1=>0, 1) -> ERR_BUFFER_EMPTY
PassThruReadMsgs(1, [{ISO15765; RxStatus: TX_MSG_TYPE | TX_INDICATION | CAN_29BIT_ID; TxFlags: 0; TS: 00:00:00.0390000; LEN: 4; ExtraIndex: 0; Data: 18-DA-B0-F1}], 1=>1, 1) -> STATUS_NOERROR
PassThruReadMsgs(1, [{ISO15765; RxStatus: START_OF_MESSAGE | CAN_29BIT_ID; TxFlags: 0; TS: 00:00:00.0500000; LEN: 4; ExtraIndex: 0; Data: 18-DA-F1-B0}], 1=>1, 1) -> STATUS_NOERROR
PassThruReadMsgs(1, [], 1=>0, 1) -> ERR_BUFFER_EMPTY
PassThruReadMsgs(1, [], 1=>0, 1) -> ERR_BUFFER_EMPTY
PassThruReadMsgs(1, [], 1=>0, 1) -> ERR_BUFFER_EMPTY
...

No any reaction on START_OF_MESSAGE 😯

UPD: Set Separation Time Min Ioctl_ID.ISO15765_STMIN.value, 5 i can read all dtc with success.

I think we need to customize ioctl configs.

[kirya-dev]

Works great with Ioctl_ID.ISO15765_STMIN.value, 0 Also in PR i add new method for formatting ID (ISO-15031-6)

Code example

with Client(conn, request_timeout=100, config=client_config) as client:
    try:
        client.change_session(DiagnosticSessionControl.Session.defaultSession)
        dtc_data = client.get_supported_dtc().service_data
        for i in range(0, dtc_data.dtc_count):
            dtc = dtc_data.dtcs[i]
            if dtc.status.pending:
                print('Pending \t' + dtc.id_iso())
            if dtc.status.confirmed:
                print('Confirmed \t' + dtc.id_iso())
