AGPTEK Rocker

[coacharnold]

I'm ready to roll on this.  I'm a linux user if that helps ... so I can trouble shoot and help out with testing if needed.  Also ... if someone can help me ... I'd be happy to help out with a wiki/install guide.

This player looks REALLY cool ...   my guess is that the Blutooth is just a matter of enabeling it in the code.    Has any Rockbox port utilized blutooth before this?

Rockbox still has my favorite interface for DAP's.

Let me know

Hi .....  without spending a lot of time looking this up .... can someone tell me, is this the player :

AGPTEK ROCKER Bluetooth 4.0 MP3 Player, High Resolution Lossless Music Player for Audiophile(up to 256GB), black /sliver

And does blue tooth work with rock box?  Is there a wiki for the install process??

I see it on wallmart's site for 50$,   I'll buy one today if it works.

Thank you

Tim

Yep, that's the device.

No BT via rockbox AFAIK.

You can clone the repository using GIT (git://git.rockbox.org/rockbox.git), the detailed build instructions (via docker) can be found in README file located at path: ./tools/agptek_rocker within the cloned rockbox repo.

cool .... found it all a few pages back ... with the exception of the info on BT >... thats a bummer.  AM I right in saying it's dual boot?

THanks for the help

Yeah, it's dual boot.

The difference is insignifican't unfortunately.

Yep about ~7 minutes runtime in my battery benches.

I don't know how, but I got 9 hours of battery life on the new build in this thread as opposed to the 6 and a half hours I usually get on the old build. Could it be due to other factors such as the bit-rate of the file?

 agptek rocker v2

I can still see the display, it may not be moving though.

i didn't see any change in battery life.

Hi, may i ask if you did anything with the test build that is different than regular build? Did you change a setting and what type of music files were you playing?

I didn't do anything to the test build, I just downloaded and unzipped it to my player's SD card. I use my Benjie T6 mostly as an audiobook device at night so I use MP3 128kbps files. My LCD brightness, however, is 5. No other settings were changed.

Id be happy to help out with a wiki/install guide.

If you want to make a tutorial, I reunited all I found on this post. I think the only thing it changed was the build, since they're testing the battery life right now.

First, i tried to reduce battery usage.
I've found that rockbox use 10-30% cpu when updating display
After disabling display update when backlight off i've got 1% cpu usage in idle and 3-15% when playing.
It is very strange: on same file it may use only 1.5-2% and may 30%. It just changes randomy on every rockbox start.
I tried to reduce timer frequences, but it only reduced idle usage to 0.7 and playing to 2%.
On "successful" launch (with 2-3% cpu usage), it may work about 11 hours from full battery change (after reducing timer freqs).

Of cause i have some questions:
1. Why not stop timers when no modules using it (when running in idle)?
2. Why use separate thread to run timer? i do not think that constantly switching process context is good for battery usage. Maybe just use signals for interrupts and nanosleep/select for wfi?
3. By default, audio buffer size is larger that used in rockbox. You may increase buffer size to reduce cpu activations while playing. Is it possible to fill buffer only every 2-3 seconds in rockbox?
It seems that firmware kenrel implementation is good, but hosted is very poor.

Are you running a recent dev version?

[mittorn]

Yes, it is 1da2708a7c48c144605d84da94d0184209713683

I bought a Rocker from Amazon. Came with firmware v 1.31 beta
It falls to update firmware. Gives me messages
 "Updater V 1.1"
 and then
 "v_v Failed"
Anyone familiar with this?
So far tried different SD cards, resetting player, writing to the card using separate card reader. No firmware update works. Not even the AGPTEK's own.
Thanks

The latest firmware version for the Rocker is 1.2
