About using adapters:

Bluetooth: Due to Apple's restrictions, apps can only support Apple-certified Bluetooth adapters (MFi). Currently supported: vLinker MS (not MC) as well as ObdLink MX+. Both adapters have SW-CAN support, which is necessary for full compatibility with the app.

WiFi + BLE: No restrictions here. Owners of the vLinker MC+ can connect via vLinker MC+ iOS, and the VeePeak BLE works too.

If you run into problems, there's an option in the menu at the bottom — Send logs / Report a problem.
