    Hi Gregg,

    Two things to try:
    1. Re-install the App and this time make sure to "Grant access to nearby wireless device".
    2. Make sure you only have one OBD2 App running at a time, otherwise two OBD2 Apps will be fighting for bandwidth and timeout.

    hope this helps,
    Jack

    People also forget to disable their car audio interface, smart watch, air tags and anything else using the Bluetooth bandwidth. Your Bluetooth has to pick through all that interference to find that new device. Best to disable everything else so your phone can find the device faster and easier.

    While not a dealbreaker, Panlong does not support Apple's bluetooth 4.0 connection. So it relies on 3.x and below, which may not be as good.

    iOS has never supported BT below 4 (v2-3 is a version from 2005, totally insecure and more like a beta version).

    Get a better/modern BT4 dongle - or use android.

    I've used a Carista OBD Adapter, no problems.

    Some of the adapters aren't compatible with dr prius. I believe there is a list on the website.
