Car scanner and ELM327 connection

Did you purchase one of the adapter brands recommended by Car Scanner?

 

There are a lot of cheap adapters out there that don’t work, despite their claims. It is always better to start with the software...

 

This might just be a dumb question but I will ask any way just in case? Did you select the Hyundai, Kona electric in the setting prior to trying to connect to the car. If not click on the setting gear in the upper right hand corner of the app. Then select vehicle options. Vehicle options is the fifth item on the list under settings. Select Hyundai, select Kona EV and it should then connect. If you already did this I would try again before changing to a different obd II adapter

 

Ok. So this is the OBD II scanner that I am using and it works well with my I phone 6 plus. It puts out a wifi signal as opposed to a bluetooth but I haven't had any problem with it. I just select it under wifi signal on the phone setting. I already owned it so it wasn't purchased with this app in mind put still it works well. I got it off of Amazon a year or so ago.

 

Very similar. I just tested mine and it worked whether the car is off or on. Just plugged it in and selected the wifi and it connects right up. I have mainly been looking at all sensors and also have checked data recording and all are working on mine. There is much more data available when the car is on obviously. Not sure whats causing your error. Do you have access to a second obd II that you could test it on just to see if you get similar results?

 

What data are you seeing when the car is off? I've not seen realtime data from my Bluetooth dongle unless the Kona is in Run mode or charging.

 

Here are two screen shots. The first is with the car in run the second is with the car powered off. Notice the difference in OBD voltage. First I started car scanner with the car in run. Then I turned the power off for the second reading. Car scanner will not connect with the power off put if it is already connected it will maintain some readings after the car is powered down. I did notice that there was no high voltage or cell readings in the battery pack once it was powered down.

Let me know if there is some thing specific you want to see and I will scroll through the data and post a screen shot if its available.

I was able to reproduce the same error you got. It turns out the car must be in run mode when you first connect to " Car Scanner" If you try to connect with out putting the car in the run mode (ready to drive ) you get the error. To correct this simply press disconnect on the car scanner app, place the car in the run mode and press connect again and you should be good to go.

 

Here are screen shots of all my connection settings. The first page is the general settings , the last three are the advanced settings. looks like there are several differences in our settings hop this helps

 

Here is the link but its currently not available. I bought it almost 2 years ago.

It looks like there are newer models but they don't seem to have that great of a ratings..

Here are a couple of links to ones that seam to have good ratings.

I'll just note that the OBD voltage is an analog measurement at the port, not delivered as network data.

 

Will it keep draining the battery when plugged in?
The power connection within the OBDII port is constantly on and provides voltage directly from the battery. If there is electricity available, the OBDII device you’ve connected to it will draw it and drain the battery.

 

I have Veepeak. My Car scanner (iPhone 11) won't connect to it. I switch to another (bluetooth) adapter I had for Engine Link for Car scanner.
