Elm327 connection with Scantool - How to connect with Bluetooth

Question

Hello, I have a problem, namely, I do not know if Scantool 1.13 can connect via Bluetooth ELM 327 at all? Is it only through such an interface that has a cable? My interface is definitely functional because I can easily connect to it by phone with the car but this application has few functions...

All you have to do is pair the interface with your computer and then select the correct port in scantool, it has two com ports detected but it works only under one. Just take into account that on cheap elem327 interfaces the refresh rate is very poor.

Thank you for your response . Unfortunately I could not connect to the scantool. Elm327 was paired, I set the task manager ports to COM 1 / COM2, speed to 38600 and later to 9600 and nothing. Is it possible that my elm just won't work with this program? Or is the program itself damaged? Although I tried from different sources.

And in scantool what is your chosen port?

This program is a terrible linden, it's a shame to waste time on it.

Especially since he is 10 years old. If not more. Choose what is dedicated to your car.

We have various cars at home so I don't want to buy a program just for my car and a program like scantool is enough for me, I only need the basic engine parameters. Unless someone can recommend a program that would work with elm327 and be free?

kkknc · Answer

Leave this face to phone. That was his destiny.
First you write that your program has poor functions (you don't know which one) and then that scantool doesn't work. There are also very few functions there. And I remind you that you wrote about the basics. And how do you know that you have enough if you haven't even started it? You didn't suggest using this product's ads?
As I can remember, I have never been able to launch this program.
And the pairing procedure is a little different in each computer. It depends on the operating system and sometimes the overlay given by the manufacturer. Some programs connect themselves and some must be rigidly connected before starting the program. And you write nothing about it.

On the phone I can only read the error codes and I cannot enter the parameters, and I want to see the voltages on probes and LTFT / STFT. I set the ports alternately from 1 to 4, speeds to 9600 and 38600, the same in diagnostic programs and cannot be connected. I do not understand that some do not connect and some do not. For me, ELM has been paired and connected. The system on the laptop is W10. What else can you do about it? I also tried other diagnostic programs that are supposed to work with this elm but the same.

tzok · Answer

Torque on Android is 100x better than ScanTool, but in generic EOBD do not count on many parameters ... unless you have a car from the USA with OBD-2 system. If you insist on ScanTool, take version 1.21, there you do not have to combine with changing the port number, it can be COM-30. The port speed setting in the port properties in the device manager has no effect. ELM-327 uses a speed of 38400bps.

And this is probably the reason. I suspect this system is too high for this program, or the proper drivers are not available. I also have programs that I don't care about under W8.

kkknc · Answer

Do not count on any universal program under ELM to see the exact voltage on the probes. And a lot depends on the car. Either at all or peak instantaneous value. Which won't make you any diagnosis.

Thanks for the answers, according to my conclusions, ELM327 is to blame in another car, he doesn't even want to connect to the phone and an elm clone detected message pops up, though not always. I have a second elm interface only that you can connect to it only via Wifi, it is efficiently connected to all cars via smartphones and tablets (programs: CarScanner, Torqe). And I have a question, can this interface be run on a PC with scantool programs? How to create a COM port?

kkknc · Answer

Greedy. Unless you write something yourself.

Killlu · Answer

Like everyone else. They only allow for engine diagnostics and this is incomplete, you can dream about AIRBAG or ABS. I was also tired with this scantool and I didn't tire anything. The author did not get the plate for this ELM327? There are programs such as PCMSCAN and ScanMaster on it - quite pleasant.
