problem with bluetooth connection

[mvs]

Hello

My elm327 adapter with this problem in your bluetooth connection, sometimes it passes the first test port multiecuscan more on the second attempt and starts giving errors like problem with semafaro, busy port, timeout

I also have problems to pair your bluetooth device I try to shut down a few times until you can pair

Sometimes it just does not accept the password (which is 1234)

Apparently the bluetooth connection seems this little crazy

I have doubts whether or not I should do the procedure in this topic because it seems to have nothing to do with bluetooth

My adapter is "china version" apparently v1.5

Sorry for my english, I'm using google translate

I from Brazil

I sent pictures of my injection. adapter and circuit

Hi mvs

First of which vehicle you would like to read
and Bj which has as there is a 3 pin connector, it is probably a little older

The coupling with the ELM must function naturally and also persist consider the ELM something greater is not directly above the battery

As you have correctly identified your problem has nothing to do with the copied ELMs

What control do you read from this connector? ECU?
Because you know that you just have to connect the controller to read.


And also your pairing code is 1234?
Because there are other codes

Greetings Eddy

First I want to thank you for the help

The following photos connector electronic injection car 3 pins, it fit perfectly in 3-pin adapter like this link

I think my car is up there because the battery is the same place that specialized workshop used to monitor electronic injection

The code is correct but since 1234 most often pairing between the pc and eml327 is done correctly

What makes me more confused, thinking that the problem must be in the bluetooth connection is that sometimes he even gave the ok "test interface connection" of multiecuscan sooner then gave error
