FM/AM Radio issues + CANBUS support

1. Issue with searching radio stations (SCAN)
Even with the RDS option is disabled, I always getting the error "Search for radio stations failed!" when i try to scan all radio stations. When this error occurs, the radio stations are not shown in the all list, and the list remains empty.
At the end of this process (60 sec. +) scanned radio stations are saved, probably in the app service in background, so I can changing them using the SWC commands, but the all list are still empty on Client-UI Radio App and I have to manually mark them as favorites to save them on all list (Next SWC command then mark as fav etc..) !

2. Formatting Issues
   When the system language is Serbian, there is a problem with the display format of radio stations, your developers probably format the stations values using Locale.getDefault() -> formatting with dot should be the standard for displaying radio stations for all languages. (This is a problem in navbar too, when I select AC temp to display on Navbar, temp value has wrong format when Serbian language is selected, also comma instead of dot).
   (For example Radio Station -> 91,3 Mhz should be 91.3 Mhz , also for navbar temp value -> 21,5* should be 21.5*)

3. AM Stations formatting issues
   Display of incorrect AM stations format (comma instead of dot) and general display formatting of AM stations is wrong

4. Saving names of radio stations issues using Editor (duplicate radio stations on the list)
   After I entered the names of the radio stations, duplicate stations appeared in all the lists, the next station button does not work, it constantly selects the current radio station, while the previous button works, also using the SWC controls, I have to press the next button twice if I want to move to the next radio station.

5. AM/FM prefix suggestion
   Instead of FM and AM prefixes for radio stations, there could be Mhz or Khz at the end of the radio station value

6. Favorites list
   What is the purpose of the radio app favorite list, since it can't be controlled by SWC, generally this is not a mobile app or music player app, so it can lead to serious safety problems (for example, while driving, I will need to select radio stations from favorites list directly on the head unit display)?
   Also the label with the name of "all lists" is redundant!!!

7. Radio Seek functionality/buttons
   Radio station seek buttons function is missing, even if you have all station search function (SCAN and Tune) , this is mandatory and standard for all radio apps, sometimes I don't want to tune 1Mhz by 1Mhz to find next station.

8. PS values should be default values for saved radio stations on all list or fav list
   The PS value should be the default value of the saved radio instead of the radio station number (for example, instead of 91.3 -> PS value (radio station name))

9. Manually save the radio stations. How to?
   How to manually save a radio station (I don't want to put it in the list of favorites, I just want to save it)?

10. SWC controls
    Switching radio stations using the SWC controls does not follow the order of radio stations on the radio app All list (for example using the SWC the last changed radio stationis before the last on the All list, after I select the first station in All list directly from radio app and then I press again the next button on the SWC it returns to the last station on the list instead of going in order, in this case it should go on second station on list but its not a case.

11. Non ASCII characters values on RDS radio information
    Please filter and do not show non-ASCII characters on RDS radio information

12. PS and RDS displaying
    The display of RDS and PS values ​​should be separated, this is not the standard to display them like this, maybe this is a test version, but definitely take a look at how other car radio applications look like

13. On Launcher desktop (Radio/Music widget) there should be support for displaying RDS informations also

14. CANBUS Switching between apps
    Since I have support to change applications using SWC controls on the steering wheel, this function after switching to DUDU OS does not work properly. For example when I listen the music player and I want to switch to the radio nothing happens, but when I listen to the radio and I want to switch to the music player then sometimes it works and sometimes not this, also switching to Bluetooth music does not work, and switching between FM and AM band. Possibly because Radio/Music player/Bluetooth are part of one application and system cant recognize it.

15. CANBUS Hiworld support
    Do you have a plan to implement support for Hiworld chanbus devices like you did for Rise canbus devices, with Hiworld I can't use DUDU app for vehicle settings, and animation for turn signal and AC informations does not work

Note: I have video for this test cases but I was unable to post here probably because of size!

Correction for test case 10:
Switching radio stations using the SWC controls does not follow the order of radio stations on the radio app All list (For example -> Using the SWC controls -> The last changed radio station is before the last on the All list -> Then I selected the first (1) station on the All list , directly from the Radio app -> Then again I pressed again the next button on the SWC
Result -> It returns/goes to the last station on the list (like it has saved last changed station using SWC commands) instead of going in order! In this case it should go on the second station on the (All) list but this is not a case).

ciubaka If you say about formatting issues, then you have to know that MHz or kHz is a proper format for the frequency. Because kilo is always small 'k' and mega is big 'M'. And base frequency unit is Hz, not hz.

Regarding the formatting issue , I didn't talk about units for frequency (MHz and kHz) , issues is only related to the formatting of radio stations when the Serbian language is set as the system language.
Displaying units of frequency is just my suggestions instead of prefix FM or AM
Since obviously not all countries (like Poland) have a formatting frequency standard as I said, then my suggestion is to add an option in the radio app settings to choose the formatting style (dot or comma), not to use system default Locale settings.

Addition for case 1
Error message from resources
Key -> search_fm_fail

danielbgd Since obviously not all countries (like Poland) have a formatting frequency standard as I said, then my suggestion is to add an option in the radio app settings to choose the formatting style (dot or comma), not to use system default Locale settings

Addition once again since I can edit my post:
In the Serbian language, two letters are officially used, Latin and Cyrillic
sr_ [Serbian]
sr_ [Serbian (Cyrillic)]
sr_BA [Serbian (Cyrillic,Bosnia and Herzegovina)]
sr_ME [Serbian (Cyrillic,Montenegro)]
sr_RS [Serbian (Cyrillic,Serbia)]
sr_XK [Serbian (Cyrillic,Kosovo)]
sr_ [Serbian (Latin)]
sr_BA [Serbian (Latin,Bosnia and Herzegovina)]
sr_ME [Serbian (Latin,Montenegro)]
sr_RS [Serbian (Latin,Serbia)]
sr_XK [Serbian (Latin,Kosovo)]

So for example if you set serbian Latin Locale there will be dot but if you set Cyrillic there will be comma
And standard for Serbian language for formatting radio frequency should be dot

I noticed another issue that happens often without any rules:

1. The navigation application was in foreground, the radio was running in the background, I previously set the navigation to start automatically in the launcher settings, the default large widget on the home screen is the wallpaper, not the PIP.
2. I restarted the vehicle after approximately 15 minutes, the navigation application appeared, but after a few seconds (3,4sec) it automatically switches to the home screen and the radio also does not work at all, I have to manually select the media source, i.e. radio, in order to restart radio again

caolz Issue 10, there are some issues with the SWC control radio switching function, and this issue will be further optimized in the future.

I hope this also applies to test case 10, switching apps using SWC controls doesn't work as it should, maybe I wasn't clear enough in this first post.
So when the radio app is in the foreground and I want to change it to music player or bluetooth player, sometimes it wants to change it, sometimes it doesn't, but when the music player/bluetooth is in the foreground, it won't switch to radio, also since I have the option to switch FM to AM signal and vice versa from, using SWC controls, this option does not work at all.

caolz Issue 9, collect radio stations and then cancel the collection.

I didn't understand this response from you, it seems too complicated

caolz Issue 1, we will fix it.
Issue 4, why are there radio stations with the same name?
Issue 8, the style of this place has been changed in the new version of the Media APP. Please wait for Appstore to release updates.
Issue 9, collect radio stations and then cancel the collection.
Issue 10, there are some issues with the SWC control radio switching function, and this issue will be further optimized in the future.
Issue 11, there may be some garbled characters, and this issue may be optimized in the future.

1. Please also take a look for test case 2, 3 about the formatting of radio stations (FM/AM) when the Serbian language is selected as the system language, this as it is now implemented is not good, I described the problem above and also I had added additional description in the comments.
2. Will buttons for seek freq functionality be added in the new media app version (quick search for the next/previous frequency)?
3.Do you have any answer regarding my question under case 15, related to support for Hiworld Canbus protocol

caolz

caolz Do as you say, I haven't seen two radio stations with the same name.
Can you reproduce this situation?

Please check the video below regarding case 4, this is old video that I have. The description of how it happens is in the post above. In the meantime I deleted all the duplicate radio freq using the editor, and so far I have no problems, although I did not try to delete everything and do the search again freqs. because the user experience and the use of the application itself is very poor (case 1 and case 8 mentioned above), I would have to save manually all the stations again, so to edit the names, and there are a lot of them, but I will try to reproduce this issue again

caolz
Yes, I discovered that myself, but I am not sure that it is good for the user experience itself
This procedure seems more like I want to remove it from the favorites list, and maybe remove it from the list completely, and not just to save the station.
