    red devil blue tooth problem

    Hello
    I am having problems with the red devil blue tooth adapter.

    I can get data when I have my devices hard wired so my ADX file works.

    blue tooth pairs with no problem.

    Using the red devil blue tooth i get no communications with ecm.

    I also changed the default baud rate in the adx file to 9600 and the same thing, no communications with ecm.

    I don't know what else i can try so I am stuck. No word from the red devil web sight.

    Any ideas would be great. Thanks

    If you have no communication with the ECM it wont work period. What programme are you using? I'm just starting with this and my whole system is custom and I had some problems getting it going.
    I'm using the red devil with ALDL droid blue toothed to a tablet or android phone. My first problem was the socket was wired wrong, my mistake. I had 160 baud going to the 8192 pin E and M reversed. Corrected this and got communication. Now my problem is the ADX file.

    You need to look at the flashing led to determine the status of the unit. I'm not sure but your ADX file that worked with the other set up may not be right for this.
    I'm getting data in but it wrong. I changed the same setting you did as well to 9600.

    The other thing also is you may have to put a 10K resistor between pin A and B. This may be taken care of when you hard wire it, but I have to have the Resistor.

    MQQN28 Thanks for the reply
    The program i am using, ALDLdroid and Turner pro RT, the same adx file works for both devices and programs just not over the red devil. Green blinking light when the blue tooth connects.
    I could try the 10k resistor easily.

    Up date

    I tried the 10k resistor between pin A and B. with engine running, blue tooth paired ALDLdroid not connected and the light on the red devil blinks red and when connected the red blinking turns solid blue and the service engine light turns on.

    No resistor, Red devil light with no connection blinking green and turns solid blue when connected.

    Blue light must be a bad thing. Still no data, not communicating with ECM.
    thinking adx file,

    Have you not heard back from Red Devil? I have heard their cust service is very lacking. I got my bluetooth device from John at 1320 electronics. Excellent customer service and he is on this forum as well.
