# CarDash 1.2.9

## Fuel economy is back

1.2.7 moved the rolling economy to the ECU's engine-fuel-rate PID (`5E`), but
the one-shot supported-PID query added in that release could race the `ATSP0`
protocol search on a slow adapter and shift every later ELM327 response by one
command. The result was a permanent `—` on the OBD card.

1.2.9 fixes the serial stream:

- warms the adapter with a `0100` request after `ATSP0`, with a longer timeout;
- drains stale input before every command so a late response cannot be read as
  the next PID's answer;
- removes the `0140` supported-PID query and probes `5E` in the poll loop
  instead, retrying every 30 cycles while it is unsupported.

The ECU fuel-rate economy itself is unchanged: vehicles that report `5E` use it
and match the car's trip computer; vehicles without it keep the MAF fallback.

The release also includes the 1.2.8 Jellyfin album navigation work: the
favorite heart moves to the left corner at 69 px, three separate 60 px volume
buttons sit on the right, the cover is 30% smaller with taller track rows, every
page has a larger back button, and both Jellyfin pages get a transparent
top-right time / speed / temperature / Home strip.

## Install

Download `cardash-android-1.2.9.apk` from the release page or the repository:

`https://git.krasi.net/kkazakov/car-interface-android/raw/main/releases/cardash-android-1.2.9.apk`

SHA-256: `3cf73d295ebe077a94c83d1aee6a7c1b4332e9eefa3048aa76c729aa7c3c9ad5`

The build is signed with the same project key as previous releases, so it
installs over 1.2.8. Android still asks you to confirm the install.
