  1. Hallo Andreas,

    du hast ein tolles Interface gemacht.
    Leider hatte ich erst eine Verbindung zum Bosch Indego.
    Jetzt erscheint der Fehler: Unauthorized (401).
    Ich bin mir sicher, das meine Email und das Passwort richtig ist.
    Hast du eine Idee, woran es liegen kann?

    Viele Grüße

  2. Hi Alexander,
    My name is Dobrin, from Sofia, Bulgaria. Sorry for my English!
    I need a help for custom development, based on your car diagnostic software (OBD KW1281).
    I have modified code of ECU (Motronic 2.3.2), which sending data trought K an L lines, instead OBD KW1281 protocol. When I set one magick byte in ECU the KWP1281 is down and the data start flow with 187500 bps on blocks of 33 Bytes (AA BB then 31 bytes of data (one byte is one car sensor data). So I get data from 31 number of parameters, 10-15 times per second with the engine running and 40-44 when engine is off. This is enough to monitor the functioning of the car.
    I use your development (with little change – I forbade some parts of the program) of car diagnostic software (OBD KW1281) to get data from ECU, but I can view the data only on your form.memdebug.
    I can’t write data into log file and I can’t convert it to the real values. This development is over my abilities.
    I try some things, but I’m not a developer and for the first time I saw Lazarus.
    I add some objects LEDDisplay4: TLEDDisplay but to select current byte, add it to this display and add conversion to the real value and then write this value in log file is over my abilities.

    Can you help with this?

    Best Regards,
    Dobrin.

  3. it’s a phantastic blog and spent a couple of hours today to browse your content. What caught my attention was the Tango / Ardumower project. I’m thinking for a while to modify my automower. Is it possible to purchase a mower with Tango set-up and sunray directly from you as custom build?
    I hope yes is the answer.
    Many thanks and greetings from Hamburg
