NEW FEATURE! You can now scan your adapter to verify firmware version and command availability.
Interface directly with an ELM327 based OBD adapter over WiFi or Bluetooth 4. The IP address/port and BLE ID are configurable. Output is in a messaging style format.
This app allows you to send single-frame data to an adapter and read the response. For example, you could send "010C" to read RPMs (response will be in hex and need to be translated manually...or "ATRV" to read the current voltage of the vehicle at the OBD port.
This app is primarily intended for developers and techno-nerds who want to be able to interface directly with an adapter and don't mind doing a little translating on the output.
This app requires ELM327 based hardware to interface with the OBD2 port of a vehicle.
Bluetooth adapters MUST be labeled Bluetooth 4, BLE, or Bluetooth Low Energy. Bluetooth 2 will not work with iOS apps.
Added ELM327 Identifier to help test your adapter!
Fixed a bug with WiFi adapters not working in some instances.
