    I recently got the Carista OBD2 adapter as it was one that was recommended by the Dr. Prius App. On the carista website, they also say that it works with Dr. Prius. I've plugged in the adapter and the Carista app finds the device just fine (though it takes much longer to scan everything that I care to like), when I load the Dr. Prius app it says "0 devices found". I can't seem to find anything on either of their websites, and have even tried searching this forum for answers. I'm coming up blank.

    What am i missing? Any help would be greatly appreciated!

    Update: had a back and forth with the dr Prius people and the missing link was that the adapter was already connected to the carista app.

    So I had to “quit” or close all Obd related apps first (both carista & dr Prius), then plug in the device, followed by opening the dr Prius app. It found the device right away and worked flawlessly. *and my batteries are looking good. Which is a sigh of relief.

    Question. Do I need an ODB2 adapter if I have Prius Bluetooth. I just recommissioned my old Ipone 6 smartphone for the purpose of running Dr. Prius and any other diagnostic apps that are available. This is for my 2018 Prius Four Premium /w 11.6" screen an 10 JBL audio system - vehicle purchased new, back in May this year.

    Verified Iphone 6 Prius Bluthooth connectivity and everything seems to work fine so far. However, I still need to download the diagnostic apps via wifi, since I am no longer using my Iphone 6 as my wireless phone (switched back to android).

    Before I start purchasing any Prius/Iphone diagnostic apps I need to know what additional hardware I is required. Otherwise it will be a waste of money.

    I honestly don’t know anything about the Prius Bluetooth model. Is that model supposed to give you diagnostic info??

    The good news though, you can search eBay for odb II Bluetooth adapter and can be purchased for around $7 (I had a $5 coupon from eBay so I got a second one for $2). The cheap eBay model has worked for me with all my apps (car scanner and dr. Prius). But they change brand names all the time so I won’t guarantee what you get will also work, but it’s not like it was wasting $100 like my first BT dongle.

    You can get a $25 OBDII adapter on Amazon. Just make sure the one you buy works with iOS. I bought one that works with Android and it will not work with iOS. It states that on the product page on Amazon. I can provide a link if necessary. I think it's called BAFX or something like that. If you get one for the Android you can use your Android phone for it. No need to have a dedicated device. That OBDII adapter will also work with torque and Hybrid Assistant and most other OBDII apps.

    Edit: Just checked on Amazon and the iOS version of the BAFX is not bluetooth. It's Wi-Fi. Here is one that is suppsed to work with both iOS and Android via Bluetooth. I own and know about BAFX for Android. This one is unknown to me, but seems to have good reviews.

    Yes. I just now realized that while shopping around for OBDII adapters. When I first got my Prius Four this year, I wanted to keep my Android connected to the Prius audio/phone BT interface and use the Iphone for diagnostics incl Dr Prius, Torque Pro, etc. BT is not capable of supporting more than one device simultaneously. Using my Iphone for diagnostics and other apps would allow me to keep my Verizon android phone for hands-free applications. The only downside to using my old Iphone6 for diagnostics is that it cannot use a wireless charger. However, I consider this only a minor inconvenience.

    In any case, thankyou for your help. You answered my question... ...I need to purchase a separate OBDII BT device to do what I want to do.

    My old Android phone with an older version 6 Android supports more than one BT device. I can have it connected to my Prius and the OBDII adapter and a BT music adapter. My gen 2 Prius does not stream music over BT, only does phone. So I have a BT music adapter that plugs into the aux plug on the Prius. All three devices happily work together on the same phone. Music goes to the music adapter, when phone rings it goes via Prius and I can see my OBDII output live on Torque or Dr. Prius.

    here is a thread i participated in a week or two ago discussing a lot of the adapters: ELM 327 device for Torque App | PriusChat

    as i said in that thread, I have carista that works perfectly with the apps (i haven't paid for Torque, but I honestly don't know why it wouldn't work) and it's only $20. Then I got a cheap one from Ebay and it also worked with the apps.

    veepak is a good one, but yeah $$$$ spendy compared to the others. I guess it really depends on how much you are willing to risk in total. The most you will spend is a total of $27 if the cheapo doesn't work. The least you could spend is $6.99. OBD2 ELM327 V1.5 Bluetooth/WIFI Car Scanner Android Torque Diagnostic Scan Tool | eBay

    I am fairly well versed in IT in general, but new to OBD2. A cursory review of these devices/apps have left me with the impression that the technology is still in flux with very little standardization. For example, many apps rely either on wi-fi or Bluetooth, but not both. Torque Pro requires wi-fi, but most other apps seem to have migrated towards Blutooth. With that regard, the Blutooth hardware appears to be quasi-proprietary and, consequently, are very limited in the number of apps that they support. Some, like Carista, amazingly, are subscription devices. The variations in proprietary devices/protocols are so numerous to basically render the market totally lacking in configuration control.

    This has led me to believe that the best I can hope for is to purchase the least expensive general purpose diagnostic app/connectivity device, as throw-away diagnostic tool, with the expectation that it will become obsolete within a few years.

    The other tread the OP said his BT adapter works with the torque app (maybe torque pro is different?)

    The carista App requires subscription if you want all the features. But you wouldn’t be using that app anyway, so that part is irrelevant. The dongle works as expected, doesn’t require subscription

    The downside to wifi is that you lose internet functions of that device while using the adapter (being connected to wifi, the device uses that as it’s source and won’t automatically use cellular). Works fine if you have a dedicated device for it.

    I know that car scanner one just has to change the settings depending on which type you’re using. But seemed to work just fine with either method.

    I just ordered the BAFX wifi (both ios and android compatible). BAFX also seems to be supported by a wider range of diagnostic apps. But, as indicated earlier, I expect that I will be upgrading to a Bluetooth device later, once the industry gets their act together.

    Thanks for the info.

    BTW, I am coming up on 5000 miles. Should I remove the OBD2 wifi/bluetooth dongle when I take my Prius in for scheduled maintenance?

    Just received my BAFX wifi OBD2 scanner - checked out SAT. However, I didn't get Torque Pro. Apparently, they're having some problems with their app and got some bad reviews recently, so I played it safe and got Fusion ODB2 which I was able to connect. So far so good.

    Thanx for all the help and info.

    You mentioned that you got the wi-fi version of the adapter (I think). I have the BT version and it works really well with my android phone. I can use my phone for connecting to my gen 2 Prius interface, my streaming audio interface that is plugged into the aux of the Prius and the BAFX OBDII adapter. All at once. It works great and everything goes to the correct BT channel. Apple, on the other hand does not work with BT OBDII for some reason. I think Carista is BT and works with iOS, but not sure. I am not a big Apple fan, though I do use iPhone 5S right now for phone purposes.

    Good luck and enjoy the adapter. I recommend Dr. Prius and Hybrid Assistant apps. I use Torque Pro, but not crazy about it. I will check out Fusion.

    so I had something written out (which I had written out many times already) when it dawned on me which thread I was responding to. I started this thread...discussing the Carista dongle...and how it WORKS with iOS. I can understand that some internet stranger claiming it works with iOS doesn't provide proof. If you'd like I can go take a video of the iphone app connecting to Carista.

    HMB!
