Has anyone successfully used DashCommand with a WiFi ELM327 device (dongle) and an iPhone? I mean to read parameters other than just trouble codes. Parameters such as engine temp, RPM's, fuel trims, etc.

I bought a ELM327 WiFi device and DashCommand but it will connect to the dongle but won't read any parameters (PID's). Just trying to find an app that works. DashCommand is supposed to be the best but doesn't seem to work at all.
