    Hey Robby,

    i tried to pair again, waiting longer and putting the receiver closer to my tires (+- 40cm), however, i was still unable to pair em...

    i guess the only thing left i can do is make that antenna thing?

    Hello all,

    I've been following this thread from the moment I found it and I have a couple of questions.

    1: would it be possible to have a SMD PIC instead of the through mount version?
    2: is the waeco set compatible and if so what are the connections that need to be made?

    I want to make my own PCB but as I don't have a PCB driling tool I would like to make a full SMD PCB, and just to save me some money I would rather buy the waeco set than the 3rd eye one.

    It's really strange that even one sensor is not been coupled, it sounds like your receiver doesn't work or has some problem.
    If you wish, I can check your interface, please send me a PM.

    Robbie, I'm hoping you can help me out.

    I've got some boards and your PIC's from LYTSPEED and recently got my 3RD Eye kits and put them all in place, but I'm not sure on what I should be seeing.

    I've downloaded your TPMS Doctor and it seems to see the sensors, but I can't really tell.

    I've put one of the sensors into a small sprayer so I can pump it up to simulate pressure in the tyre as I don't want to mount it on the car yet.

    1 of the sensors shows 1.8psi, the other 3 show - .4psi which in itself is interesting since that means they're in vacuum, but it's so small I'm not worried.

    When I try and run the TPMS config tool and select pair, then pump up the sensor, nothing happens........... I don't know why one sensor shows higher than the others.

    Only thing I can think of is that when I was soldering the boards in place, there was a resistor I think in the place where one of the pins from the PCB needed to be soldered. I'm not sure if I need to solder on one side or the other side of this resistor, I'll show a picture below........

    Can you tell me the best process I can go through to test my sensors.

    I have 3 kits in total, 3 USB interfaces and 12 sensors to sort out.

    1.) Do you use latest TPMS doctor and learning tool?

    2.) Did you try clear data?

    3.)Try learn sensor which show you 1.8psi to other location. Maybe is sensor defect...

    4.) About resistor, If I remember I have connection trough resistor but Im not shure, I think here in this thread are Robby say if is important to make connection on both side of resistor. Maybe if you quick check pages you will find this...

    1) Yes used the latest versions
    2) How do you clear the data ? It's not obvious
    3) I'll try this and see what happens....
    4) I've had a read through all of the pages, but couldn't see anything obvious.

    You've should have found how to reset values with TPMSDoctor.

    I've also read thru the pages and put links to the most interesting posts at bottom of page. Amongst other things how to reset learning and data.

    2) Hold Shift button on your keyboard then click Robby's logo.

    Wow thank you so much bes51659, that is very very useful, I'll give this a go tomorrow and see how I get on.

    You should remove the small resistor and solder JP1 on both sides.
