It would be great, if the eDash would support connecting over the serial bus interface and not only Bluetooth. I am currently using RealDash app connected through RXD/TXD (FTDI USB) to my Android head unit with EMU Black V3. The eDash app looks awesome and i would like to use it instead of RealDash.
At the moment, this feature is not yet on our roadmap, as we are currently focused on improving and stabilizing Bluetooth-related functionality.
That said, this idea has already been brought up by other users as well, so we will definitely keep it in mind and analyze the possibility of adding support for serial (wired) connections in the future.
