"Chinese Post", and it takes a month.

It's shipping out of the Netherlands ....

Darn CB not only does professional work but can populate a spreadsheet! :D

Strange as it sounds but I can't wait to part with my cash...as will be one step closer to getting this piece of kit.

So to save me having to re-read this thread, users of this need:

1) A working lighter socket*
2) An OBD dongle (or does this come with the kit)?

* Ask as my lighter fuse kept blowing when used for phone charging...so will have to get that sorted prior to delivery.

Bob are you anticipating Sept or Oct for shipping?

... nothing else (except Reverend Sam who didn't opt for the ELM327),
unless a software update comes out, you'll need a micro-USB cable to a computer.

Shipping I think will be late September
Every single unit will be tested before shipping out, so not all will be shipped at the same time.
I'll follow the list order from 1 to 14.

Thanks Bob. I'll take the standard, tracked shipping, same as MarkyUK. Looking forward to this! I already PM'd you my PP address as you know - just tell me when you want payment and I will transfer the funds.

I saw your PM, but since I get those a lot these days I don't answer all of them.

Forgot to reply about the working lighter socket, yes it will have to work.
Unless you go with a hard-wiring solution
As I have to, since I already have something else in place of the socket.
And then a 12 to 5V converter is needed.

P.s. I checked my spreadsheet, it has 1048576 rows, of which 15 are occupied.

No worries. I wasn't expecting a reply! :)

LOL - I just checked, and you DID reply! Still no worries :)

I assume this gadget will work seamlessly without the need to turn it on or connect it via bluetooth every time one starts the car. I also assume the user can select what to monitor for the upper and lower gauge (dependent on what is available for the year). I would prefer to have volts and coolant to check. Although I would like to be able to switch to gear box which is available for 2014. I currently use the torque app connected to an ELM327 and it's a PITA. I'd rather pay a bit extra for quality parts and a factory look so there is no messing around. This is a a very useful and clever gadget. Kudos for the design and location selection. We're all going to be rocking a Cabrio Bob gadget soon in our Jag's soon.

Today the "cheap" ELM327 was delivered. I tested this one with the ESP32, and it is working OK.
However, this one doesn't seem to go to "sleep" if no activity takes place, so I'll opt for the more expensive one
which is confirmed to go to sleep after 30 minutes, saving our car battery.

https://cimg8.ibsrv.net/gimg/www.jag...a9fd91354e.png

I found out that the ESP32 doesn't want to connect to another ELM327 if connected before to a different one,
more to be read about that here (post #19). Once I have done this ESP32 "reset", I was able to connect to the ELM327
using it's advertising name or the MAC address. Using the name is preferred,
since this enables me to write universal firmware (*4, one for each unit combination).
For this I have to make sure every ELM327 I order has the same advertising name. (for a Vgate iCar Pro 4.0 this is "Android-Vlink").

There are still some parts to be delivered from China, one of them seems to be stuck at customs for a week already

Updated list, see below.
I removed Reverend Sam, he didn't respond here, and also not to a private message.
On Thursday August 27 at 08:00 AM CEST I will close the possibility to sign up, and start ordering the amounts of needed ELM327 and 3D prints.
The sign up also closes when the amount of 14 people is reached.

Hey Cabrio Bob,

I needed Fahrenheit & miles please.

oops! OK I changed that.
btw, if it is delivered with the wrong units, it can be changed easily afterwards.

I received a private question:


Just one double check, this will work on a 2011 right? I see that you have a 2007, and I don't know if any of the back end coding changed.

The device will support the following OBD protocols:
  1. SAE_J1850_PWM_41_KBAUD
  2. SAE_J1850_PWM_10_KBAUD
  3. ISO_9141_5_BAUD_INIT
  4. ISO_14230_5_BAUD_INIT
  5. ISO_14230_FAST_INIT
  6. ISO_15765_11_BIT_500_KBAUD
  7. ISO_15765_29_BIT_500_KBAUD
  8. ISO_15765_11_BIT_250_KBAUD
  9. ISO_15765_29_BIT_250_KBAUD
  10. SAE_J1939_29_BIT_250_KBAUD
The 4.2 models make use of the 6. ISO_15765_11_BIT_500_KBAUD
I don't know and can't check what protocol the 5.0 models use, but if it's not on the above list, there's room to enter a custom protocol.

Cabrio Bob 08-26-2020 11:40 AM

some parts delivered.
 
Today some parts were delivered,
below a photo of it. The OBD2 dongles I was restricted to 8 pieces on Amazon, so I ordered later some more which are still on their way.
Also I started the 3D print order, they will be printed as the 2nd image below.
Firmware upload for the future is also improved,
it now auto-detects the correct COM port, and a selection menu for the units is made. See YouTube video below (There is a typo, can you find it?).

Thanks for keeping us up to date, Bob!

yup! :icon_cool:

paulgorringe 08-26-2020 11:52 AM

Great to see the parts arriving.
Unfortunately this means a load of work for Cabrio Bob.
Hope all of us being fortunate enough to have Bob make these for us are generous with the payment :icon_toast:

RedRider48 08-26-2020 09:52 PM

Nice work mate! Thanks for your efforts.

Rahtok 08-27-2020 10:43 AM

Damn fine idea and thread here! I would have jumped in to get one myself if there were any left. :D

Eagerly looking forward to seeing how this first batch goes. If there's a 2nd run, I'm in.

Which is why I shall be dropping CB a few extra shekel's for his effort..I hope everyone else does too when we have the final price?

I'll give some immediate feedback (as doubtless Barnsie will too) as we are probably going to be the first to receive. :)

Yeah - the minute it's here, I'll report back!

Cabrio Bob 08-27-2020 11:41 AM

I'm not sure yet if there will be a 2nd run,
I do know that at some stage I will release everything so anyone can create one by themselves.

In some earlier posts I mentioned problems with the photo resistor,
turns out that the ESP32 can't operate all pins which are called "ADC2" as analog input when Bluetooth is activated.
The photo resistor is connected to one of these pins (GPIO2).
Since the PCB's are already delivered, I'm going to make a bypass with a wire to GPIO36, which will fix this problem.
In below picture this wire is just visible.

One other thing I found out, is that some ESP32 boards sometimes are having problems being programmed when the display is attached.
In the end it manages it, but only after 5 or 6 tries. When the ESP32 is detached from the PCB it is being programmed in one try.
Probably a power issue. (or I'm using a bad USB cable)
