Dongle test script

Connect the dongle, start the car and make a terminal connection with the dongle.

There is an automated testing process in the experimental section of CanZE, right now under the “Playground (Jeroen)” screen, but it will move up to production soon.

If you insist on trying by hand, install something like Bluetooth Terminal on your Android device, and connect to your paired ELM dongle.

Send atz first. For knockoffs, all answer will be lies, but ELM327 v2.1 is a worse lie than ELM327 v1.5.

Now send the following commands:
ate0
ats0
atsp6
atat1
atcaf0

All should answer OK

Then try

atsh7e4
atfcsh7e4

If all answers are OK, that is good and go on. If not, forget it, don’t even try this dongle with CanZE. Now try

03222006

Something should come back starting with 06622006. If not, dismiss this dongle.

atcra699
atma

You should see a new line with data about every second or so. You can stop it by sending atar

If it works as expected, there’s a reasonably good chance the dongle will work for CanZE.

    Hi, I just entered the AT commands for my 1.5 ELM Wifi, but after entering “03222006” I got the response: “No data”.

    I guess this is not a TWIZY issue, but a ELM-manufacturer issue, right?

    You are trying this on a Twizy? That is a way different architecture (and we have no support whatever for it in CanZE; get me a Twizy and I promise I will do it 😉 ), and no, it is not the ELM. The commands you gave mean
    “get odometer from the motor controller”. The Twizy most probably does not have the EVC on address 7E4 so there is no reply.

    However, if you get no errors on the atcra699 and the atma commands, the dongle itself should be fine.

    Also note that CanZE (for Android) does not support WiFi, as Android will stop you cell network when it connects to WiFi.

      Thanks for your quick response! I get no errors,but I also get no messages when setting ATMA. I ordered a bluetooth dongle recommended by you.

      To be honest, I don’t want to use CanZE, but use ELM to modify recuperation via CANopen SDO.
