Multiecuscan

Hello Everybody,

hope anybody can help me about the “COMMAND: ATZ / Connection timeout” error message Multiecuscan 1.6 (free) version is throwing during my software evaluation attempt. My car is a LANCIA Ypsilon 1.3 JTD D.F.N (robotized gear shift) and the interface is a Bluetooth ELM327 V.1.5 (from Hong Kong).

Please consider the following steps I made so far:

1) Tested the interface with Torque app from Android tablet and everything was OK beside the fact I was not able to reset the service message and therefore I needed to refer to a more specific software like MES;

2) Using a notebook installed with Windows 7 64 bit and an external Bluetooth dongle I tried to install the Bluesoleil 3.2 drivers which came with the interface but immediately realized that this version was not compatible with my 64 bit Windows O.S. and therefore immediately switched to a more recent and officially compatible BlueSoleil 6.0 version which was in fact able to properly instance the Bluetooth device a couple of COM ports;

3) So I preventively managed to apply the interface mod by removing the “121” resistor as already described many times in the dedicated thread on the present same forum;

4) Then I managed to reconfigure both new COM ports setting the “Bits per second” parameter to 115.200 (as per MES manual in the case of Bluetooth devices) and lowering the two buffer related parameter to the “1” value;

5) The same (COM port reconfiguration operation) was applied to the additional COM port which was created when I searched for a new Bluetooth peripheral (the ELM327 interface) from the Bluetooth Devices window in Windows 7, which was in fact immediately successful;

6) Pairing and connection opening operations were both successful when performed from the dedicated O.S. Bluetooth window;

7) So moving to the MES application unfortunately I found that the “Scan For Interfaces” functionality is not able to automatically configure any kind of interface;

8) Also forcing the configuration to the correct parameters (ELM 27 1.3+ Bluetooth / COM 6 / 115200) ad testing it just always gives me: “COMMAND: ATZ / Connection timeout”;

9) BTW, as already read many times in different threads on this same forum I tried to update the COM port driver with the one download from the FTDIHIP site but it seems not to be compatible with the virtual COM port driver installed by the Bluesoleil installation package;

10) FYI, I already managed to try different combination of COM ports and relevant connection speeds without any luck even if some of the leds on the interface appear to blink during the connection attempts. One thing I noticed is that when I successfully pair and connect the interface in Windows and then move to MES to try to do the same (e.g. pushing the “Scan For Interfaces” button ) apparently the connection in Windows drops, but I’m not sure whether this is correct or not.

Any clue on how I can fix the issue?

Any help would be highly appreciated and recognized.

Is anybody able to provide any kind of support or just an hint regarding what the problem might actually consist of? (perhaps should I post the request in a different section of the forum?)

Any help would be really appreciated!


Thanks!!

OK! I do not know is it going to be helpful but here are some informations.
All ELM BT interfaces do not work with android system and Windows.
I have few of them and I am using them separately (for tablet and PC).
In MES open Settings > Interfaces and select only BT interface.
Sometimes you have other interfaces like VAG or ELM usb and BT interface does not work when all other are connected.
And keep in mind that china clone ELM BT interfaces have very BAD bluetooth signal.
Sometimes I had to put interface on my tablet or PC to get connection...

Hello alfa156sarajevo,

thank you very much for your kind reply and hints. In fact what you wrote appears to be the description of quite common potential compatibility issues, which I already read of many times in several threads also on this forum, that affect many of the interfaces coming from HK and China. What you wrote about BT interfaces working fine in combination with Android devices and apps but not with Windows PCs sounds really weird, but it might be my case too.

Just a couple of more questions please:

1) When you say “In MES open Settings > Interfaces and select only BT interface.”, do you actually mean select “ELM 27 1.3+ Bluetooth” option? Because in fact this is what I mainly tried with.

2) What do you think of buying a second interface, the very same ELM 327 device but this time not the BT version but the one provided with the USB wired connection? There are few offers out there on the Net (including eBay) which provide such “OBD2 ELM 327 V1.4 “CAN modified”” interfaces, which should definitely fix any kind of potential connection issue between my PC and the car’s ECU. What do you think?


Thanks!
Matteo

... uh, and of course any further suggestion from anybody else in order to fix the problem using my current interface would be very welcome!


Thanks!
Matteo

1) Yes. In settings menu select only "ELM 327 v1.3+ Bluetooth". On all other interfaces #2, #3 & #4, select "None". Than it should work.

2) Yes, you can try to buy ELM 327 USB version. Than you should connect to your Lanciy Ypsilon 1.3 jtd. If you are going to have problem with CAN network just open topic "Faulty ELM interfaces..." and there you will find the solution. I am sure Alfaeddy will help you...

Hello Everyone,

for the benefit of those that may experience the very same problem as me in the future I want to post my final update for this thread. Following the suggestion from alfa156sarajevo I bought a new interface, basically the very same ELM327 interface I already have, but this time an USB wired version marked “1.5a”. Actually also this sample of interface required the usual circuitry mod (the “R04” resistor removal in my case) but beside this the interface was smoothly detected and installed by the operating system (Windows 7 64 bit) using the bundled drivers and recognized by the Multiecuscan application using the recommended settings as per the official instruction manual.

So finally thanks again for the hints and the overall support, very helpful indeed!
(For what concerns me the thread can be successfully closed)


Bye,
