Thats great Bob thanks. I was already on the list so please advise how, when and where do we pay you. Also could you let me have a link to your website. Thanks Keith.

 

Website link is in my signature

 

So it is - and payment details please Bob.

 

Hi bob, put me down for one thankyou 👍👍

 

Brilliant Bob, I'll nudge the guys on the other site now

 

Hi Bob,
could you add me to the order list?
many thanks

 

Payment is not due yet, I expect to receive parts in 4 weeks or so.

 

Hi Bob!

I managed to put together your project and have tested it with a UNO + Bluetooth module so far.
I ordered the Vgate iCar Pro ELM 327 OBD2 Scanner BT 4.0 (which you recommended).
I tried it today but unfortunately after the connection, I keep getting the ELM STOPPED error.
I see this:

Do you have any idea what the problem might be?
Thank you very much for your help!

 

Hi all,

if someone is still trying to create the project themselves, be sure to use version 2.6.4. For 3.0.1, you receive this error message:

 

Final, final round order list:
- KMVW
- scjordan1969
- 427MikeB

6 pieces left

My previous post (#700) is still valid:
If you still want one please reply below.
Please note: people who previously showed interest have priority.

zoszabo72p,
it looks like you already solved your problem?
The version 3.0.1 you mention must be the ELMduino library.
I haven't tried that version yet.

Initially I started with an Arduino Nano, but changed over to an esp32 devkit v1.
My code is adapted to that.

Since you're running an Arduino UNO you might expect problems with the SSD1283A library (link to arduino forum)

 

Hi Bob,

Unfortunately, this has not yet been resolved.

The PowerBroker2 ELMduino 3.0.1 library can be used if 'if (myELM327.status == ELM_SUCCESS)' is replaced by 'if (myELM327.nb_rx_state == ELM_SUCCESS)'.

I also use ESP32 Devkit v1. It also communicates nicely with the Vgate iCar Pro ELM327 ODB2 scanner.

The problem is that all values are 0 or -1 when I try to test in the car.
On the phone, all the data comes nicely in the Torque app, but the Arduino doesn’t get any data.

I’m still trying, but I don’t really have an idea what the problem might be.

 

in your profile I see you own a Mazda 6.
This might help:
Find out which OBD protocol your car uses, and set the correct one:

Hi Bob,
add me to the list

wj

 

I'd go for one of these temperature displays also?

Am I too late...??

Ta in advance,

Iain .

 

legacy4cam,
you're not too late.
but others who were interested before do not respond.

Final, final round updated order list:

To any fence sitters out there, this unit that Bob has created is really very neat and works with the interior very well. It's great for the peace of mind. Mine has performed flawlessly since I got it. I put the supplied board in the printed holder I had made and plugged it all in. It worked without fuss right immediately and has always worked on a car that's only driven on occasion. It's a 5 star buy.

 

An update,
the parts were delivered early,
I will be able to ship out the 5 units the coming weekend.

 

Hi there what was the upshot in the end with the rpms can it pick them up?

I’d like to use something like this with rpm based 12v triggers for valve based exhausts - so for arguments sake from 2500rpm to 4000rpm enable the 12v trigger.. how hard would this be?

many thanks and keep up the good work

 

I realize I am too late for the ashtray device. I was and am still interested but got busy and forgot to order. Let me know if there is another opportunity, sorry about that.

RPM has never been a problem,
and your idea is easily implemented with a ,
use this kind of sketch,
add to the header to which pin the relay is connected (in this example it is 3):

in Setup, add the following code:

in the loop, add the following:
