Q: Does DAB-Z support fallback to FM Radio?
A: No and it is not planned due to technical reasons.
Q: Why do some stations appear several times in the list but have all the same content?
A: This is an annoying behavior of the broadcasting stations. DAB-Z does not lump them together to give the user the choice to pick one into the favorites list that has the best signal strength.
Q: Is it possible to add a sort of buffer to bridge short reception outages and therefore interruptions of audio, e.g. while driving through a tunnel?
A: No. DAB is a real-time, live (but digital) broadcast (same as old-style TV and FM radio), in contrast to streaming. The broadcasted data that is lost due to missing reception cannot be recovered or re-requested later. Also, DAB cannot be read-ahead in contrast to streaming. An app therefore cannot create a buffer of "future" data in order to have data locally, which can then be used to bridge the loss of reception.
If you encounter an issue with DAB-Z, I will maybe ask you to provide a) logcat logs or b) raw recordings.
a) logcat logs are created by pressing the logcat button in DAB-Z Settings -> Info (at the very bottom)
A zip file is created and you will be able to choose what to do (send via Email, add to Google Drive, etc...). Get this zip file to me somehow.
If I additionally ask you to enable "OMRI verbose logging", then follow these steps before creating the logcat as above:
1. Enable Developer Menu: tap 7x on DAB-Z Settings->Info->Version , then go back, a new menu item appeared "Developer options" at the very bottom
2. Enable OMRI verbose logging
3. Close DAB-Z
4. Reopen DAB-Z
... reproduce the issue ...
5. Create the logcat DAB-Z Settings -> Info (at the very bottom)
b) raw recording are created by this procedure:
raw recordings are done using this procedure:
1. Enable Developer Menu: tap 7x on Settings->Info->Version , then go back, a new menu item appeared "Developer options" at the very bottom
2. Enable OMRI raw recording (you don't need to activate verbose logging)
3. Close DAB-Z (raw recording enable/disable requires a restart of DAB-Z)
4. Reopen DAB-Z
... reproduce the issue ...
6. Go to DAB-Z Settings and disable OMRI raw recording. Restart DAB-Z again.
Afterwards, files with ending .raw exist in:
<internal memory>/Documents/DAB/rec/
Download them all from the head unit, zip them and send to me.
