AGPTEK Rocker

[wodz]

Ok, so I was able to patch update.upt. But I'm still not able to flash it, since I could not find any firmware that would flash on my unit. I get the same "Insert TF pls", "Updater V 1.1" and "v_v Failed" every time. Tried 2 different cards formatted by the player.

Are you able to flash unpached file at all?

I am looking for help how to organize BT ui in rockbox and how it should operate (I am really bad at UI design). One should be able to:

• Turn ON/turn OFF bluetooth
• Scan for nearby devices
• Add new device (connect and pair)
• Remove previously added device (unpair and remove)
• Something else? Maybe view known devices list?

I think linux tries to connect to known devices when BT is started. Mockups and comments welcome (BTW. I find agptek firmware UI pretty confusing when setting up BT).

No, none of the unpatched firmwares work.

No, none of the unpatched firmwares work.

I can't really help in this case.

Hi! What about always working screen? Have any ideas?

[wodz]

I can't reproduce on my Agptek, sorry.

Although I'm not sure of the practicality, being able to change/accept the BT pin would be useful. I've noticed that there are some incompatibilities with the HiBy BT feature due to its extremely limited pin functionality (i.e., it can only be 0000).

And although not UI related, I've noticed that when connected to some of my everyday BT systems, it will do one of three things:

• Audio plays fine but no track data (title, album, artist) is displayed on screen
• Audio plays but in a distorted pitch
• Player fails to connect to BT device altogether

The software isn't terribly old on my devices. It functions as per the first item on my list on my 2013 Camry and functions as per the second item on both a 2018 Mercedes B180 and 2016 Chromebook netbooks. I'm puzzled as to why there would be these incompatibilities.

Turn on bright light and look at the bottom of the screen at an acute angle

I assume this player is a backlit color lcd screen, the screen being on really doesn't draw much power and the dev effort would be better spent elsewhere

I'll echo NotableFrizi's request for supporting non-zero PINs.  Not sure if that's fixable without bypassing the hiby "system server" bluetooth glue and doing it using native linux commands.

The first cut might be to mirror the agptek firmware UI.  It's kind of clunky but does mostly work.  Mostly.

FWIW, I've managed to completely crash the Rocker 1.2 firmware this morning trying to get it to play nicely with my car's headunit (aftermarket JVC).  And even when it was working the audio would randomly break up badly.   The head unit could control next/prev track, but nothing else worked -- no track information or any meaningful status.  I don't know if there's a way to hook into that.

At $dayjob I have access to a high-end bluetooth sniffer/analyzer.  I'll see if I can find out what's actually going on.

Seems like there is no simple way to support non zero PINs :-(

Finding helps about the following issues :'(

I have installed Rockbox but sometimes it fails to load the os. (after a couple reboots it seems ok now) -- why?

And now playing problems from Rockbox:
- playback occasionally creates a burst of static before a song starts
- the playlists still don't work properly; the m3u files in the \Playlists folder do not work, but those in the \Music folder do
- powering down sometimes shows some kind of fault... but it flashes too quickly for me to see what it says

Is there anyone can help?

This is normal behaviour to have to boot into HiBy after first installing Rockbox.

And now playing problems from Rockbox:
- playback occasionally creates a burst of static before a song starts
- the playlists still don't work properly; the m3u files in the \Playlists folder do not work, but those in the \Music folder do

1. Many others in this thread have reported the same thing, but as wodz can't seem to recreate the problem (or at least, his ears aren't sensitive enough), it has yet to be addressed.
2. The playlists use relative paths, so M3U playlists in the music folder will work fine, but if moved anywhere else, they will not find the specific files. My workaround is to first load the playlist in the music folder, then save the playlist again in Rockbox as a .m3u8 file, which uses full paths.
3. This seems to be normal behaviour for my player. No unwanted side-effects have sprouted up due to the termination code.

I don't have this player, but would the second point not depend entirely on how you created the playlists?  Doesn't sound like an issue specific to the rocker or to rockbox, if the playlists don't have the correct relative pathnames they aren't going to work.

I export mine from my music manager on the PC (after ensuring I have the same music directory structure on the PC and on the player), and it took a bit of thought to ensure it had the correct options to set the paths correctly (i.e. such that entries began with "..\Music\"  - with the leading double dots)

Thank you so much for all your answers! Sorry I haven't checked the posts before.
I'm a newcomer here, and still need some time to figure out how this forum works!

At last, I would like to know if anyone feel uncomfortable with the volume control with AGPTEK ROCKER just like me, it is very slow, I mean, when holding the button, it should also gradually accelerate how quickly it changes.

Can I hope this will update in the future firmware?
