Update 2021-05-14:

A new version, a bit of cross-promotion for annother variant (USB DAB modules) - and some interesting new insights ...

I have managed to build a new app with the same UI concept, but this time for USB DAB receivers. I know there is already the excellent DAB-Z, and I want in no way compete with it.

I just like simplicity; that's why I transferred the UI part of the "old" app to the one for USB.

In the process, I also added some improvements to this one, so there is a version "2.0.0" now.

To help with future updates and statistics, I published it on Google Play:

DAB+ Radio for Klyde HU Module - Apps on Google Play

Control serial DAB+ module by Klyde - only for special hardware, NOT for USB !!

play.google.com

Changes included against the old version here:

- Some UI changes, nothing fundamental

- Now up to three text chunks are displayed, eliminating the frequent change

- Station lists are ordered alphabetically

We are MONO !!

At some point I realized that there was definitely no Stereo audio when listening on the DAB+ app. First I suspected misconfiguration, maybe the wrong MCU firmware. However there were no changes, whatever I tried. What's suspicious though is that there is signal on both speakers. That implies that the distribution to both channels must be done deliberately at some point, else only one speaker would get a signal.

Anyway, for the new development, I pulled the headunit out of the car and set it on my desk. This allowed me to run hands-on experiments. And voilà: I managed to stick some thin cables into the output plug of the module - and got regular Stereo sound out of it immediately!

It turned out the cable of one of those channels was CUT right before the HU plug !!!

It seems that there was a lack of pins in that plug/socket, so only one channel goes into the HU and is obviously routed to both speakers internally ...

Original post:

With my new headunit (PX5 Oreo from Autojeta, based on Klyde KD-7602), I had ordered an external DAB+ module which is connected with a proprietary cable to the rear socket panel. It has a serial control connection, power and likely a TOS audio wire.

The app for operating the module which was offered for download is incomplete, to say the least. Presets weren't working at all, it was not even possible to save any.

So I did a bit of re-engineering and built a DAB+ controller how I imagined it.

Changes against the original:

- Many, total rewrite

- Infotext is complete (the last character was always missing before)

- New layout, eye- and finger-friendly

- No more ugly images and buttons

- Plenty of room for long infotexts

- Presets are working

- Setup window for less-used options

- Unnecessary permissions and resources removed

- German translation included

Update 2019-01-30:

- extended compatibility down to Android KitKat (4.4)

- empty preset entries can be clicked anywhere to set; no need to hit the edit button

- attempt to make layout independent from resolution

If anybody is interested, I can provide the "strings" files so that more translations are possible.

Enjoy!

Current version: 1.2 (obsolete, see 2.0.x on Google Play)
