Hi!
i would like to thank anyone that contribute to this thread, and especially Alfaeddy for his precious help.

reading this thread I was able to get my interface working flawlessly.

My interface has the same pcb (there is written 2012-02-06 b1uwOBD V1.6 ) as betyargabor (page 36) and fiatbravoemotion (page 38), but it's a USB one not a bluetooth one.

Removed the R04 and it works!

The only difference I've found with other similar interfaces is that it has a Silicon labs CP2102 chip instead of the usual FTDI chip.

I've found the driver here: http://www.silabs.com/products/mcu/Page ... ivers.aspx

PS.: I'm sorry for my bad english

Hello Flame79

Thank you for your contribution
and above all that you read in previous posts where ever the problem is

The driver problem I had to talk to a user of the

http://www.alfa-romeo-portal.de/arcommu ... -blog.html

He has had the same problem with his laptop and with the daughters laptop
but it works. Then he inquired about why Google is so


and of specific part of the USB chip does not come with the usual drivers cope

But in the meantime I had already forgotten
I get older

Thank you for your driver link

Hello Lolo85v

Nice that it works now!
It could then only be a problem on the interface

Hi Eddy man,

Few questions for you:
- do you have experience regarding ELM 327 WiFi OBD interface?
- did you manage it to work with MES?

I have clone elmWIFIobd and it works with AOBD but not with MES.
In test mode everything is perfect but in real connection does not work...

Hi Alfa156sarajevo

No I have not yet tested WiFi interface and can not say anything to

But was already thinking to buy me one, in order to test
Which WiFi Elm you?

I have elm 327 wifi clone. Had problem with r4 resistor.
Removed it and it is working fine with AOBD and ScanMaster 2.1.
It works only in test mode with MES. It is not working in real conection.
I guess it is a bug in MES.

I guess it is a bug in MES.

Hi alfa156sarajevo

Hello everyone. is the first time I write in this forum and I can tell you that I have just purchased the interface elm327 with wifi v1.5 MUS I can only connect to the engine control unit. gives me problems with the connection with the other control as the body or resetting service. I read that I have to remove the resistor R04 to operate the interface. sure which is the exact procedure? sorry for my english
