I was surprised today to discover that iOS 18 seems to have broken the ability of my iPhone 15Pro Max to connect to a WiFi OBD II scanner that I use when diagnosing my car.
This is an old scanner (I honestly don’t remember how old, but less than 10 years), it plugs into the OBD port on the car and when the ignition is in AUX mode it powers up. I connect to the WiFi “network” it creates and then connect the app, and I can run diagnostics and clear some CEL codes, etc.
Now, since 18, the phone sees the WiFi that the OBD creates, then it refuses to connect. I’ve resorted to pulling out my old iPhone 5s and running an older version of the scan app, and that seems to work, but it is annoying that something that did work on the iPhone 15 in iOS 17 and all it’s variants, does not work now.
Anyone else having issues connecting to older WiFi kit?
