MK802IV New Wifi Chip AP6210 - Neomode Custom Rom Version 1.0

[humpty_dumpty_empty]

I don't know if this will work or not (I don't have my RK802IV yet so I'm testing on my Nexus 7 and everything works so I don't get any error messages)

Can you do the following?

- Install a terminal emulator from the play store (I used 'Android Terminal Emulator').
- Type 'less /proc/net/dev' and reply with the output?
- Type 'su' and allow the terminal emulator root access
- Once you have su access type 'svc wifi enable' and post any errors?

Hello Padriac,

Sure, will do and get back to you soon.

Quick query around hardware soldering - I resoldered the wifi antenna with the chipset wire. however, while soldering I have clubbed the thin outer wire mesh along with the tiny single core wire as well. Will that be an issue? Is it that only the central thin core wire need to be connected with external antenna or if twisting the wiremesh and central core wire should still work?

Thanks.

Yes that is a problem, it has been the biggest problem on pc sticks since the start of them. When both of the wires are connected it will give u an unstable wifi reception. So try to resolder the wires without twisting. This way u will have a very stable wifi signal. Single core wire is for the antenna while the wire mesh is for the ground.

Neoal,

Thanks for clarifying on that, I thought that's how antenna wire was... Kind of like TV coaxial cable http://en.wikipedia.org/wiki/Coaxial_cable.

Hello Padraic,

Thanks, I've android terminal emulator installed. Please find the ouput after executing the less command:

soinfo_relocate (linker.cpp:975):cannot locate symbol "_set_syscall_errno" referenced by "less"...CANNOT LINK EXECUTABLE

I'm sorry I am not a techy developer and new to android. Not really sure what that means and request you to plz guide on the same.

Also, the next two commands su and svc wifi enable did not through any errors and nothing happened on executing those commands.

Hi Neoal,

Thanks for your confirmation on the wiring. Quick note though - even if the wiring is messed up should it really auto switch off the wifi within few seconds when I'm turning it on forcefully every time? atleast it should search for the networks around or kind of continue with the searching bar and then show the output that no networks found or something..

Ofcourse I will re-solder the wire mesh thing but my hunch is the problem lies much earlier with the drivers or something.. REquest your inputs plz. Thanks.

Update - Plz find my DMESG output attached here.. dmesg.txt

i know for sure that if you twist the wires of the wifi cable, it will mess the stability of the wifi signal while for the autoswitching off i think that it must be a problem with the wifi driver. (not certain of this) ive been having a problem like this when i had the mk808b and flashed it with the mk808 rom. i turned it on and after 3 sec it was going off again.

For the devs or someone that has tried this pls take a look at my post here: http://www.freaktab.com/showthread.p...OR-THE-MK802IV cause im planning on buying a mk802IV and i would like a little bit of help. thx

Can it be that the problem is the gpio address is different on this Device?

Check the nvram.txt and ap6210.txt in firmware folder.

Hello Padriac,

Not sure if you had a chance to look into this. Could you plz guide if you managed to digg into this further? Thank you.

Gents, I have the s400 green sticker with that wifi chip, with versions 1.0 & 1.3 I obtain wifi, but the speed is very intermitent ..

I will try to check with the manufacturer, hope somebody finds a solution ..

Last but not least, neomode 1.3 looks awesome !

Hurray Wifi Started Working

Hi Padriac/Neo,

Quick update - I installed factory ROM again (after series of other stock roms too) and finally managed to get the wifi working on one of the factory ROMs. I will share the dmesg.txt soon for the experts to anaylze the problem so that if possible you can help me incorporating it with your 1.3 ROM as well. Thanks.

Hi,

just flashed rom 1.3 1024p version on my mk802 iv, looks great!

first off, thx for all your work!

however, one small problem
wifi is generally slow.

i could barely watch netflix and even accessing smb share takes ages.

also i see the wifi icon go dead now and then.. like it lost connection and has to reconnect again and again.

yes, its the one with new wifi chip, my manufacture date is august.

i tried setting my router to:
b
b/g
b/g/n

to no avail.

any ideas how i can get reception better?

if i use my old mk802ii wifi connectionwas almost decent on that with stock rom...

[deathkill]

did anyone try an xbox classic controller with this rom?

i just stripped the cable and connected an usb and pluged it into the GTO usb port and it seems to work
at least i can navigate the menu's and select items and stuff.

but if i start a game it doesnt work anymore..

does anyone have experience with controllers?

are there games that will work with xbox classic controller?

i read somewhere gameloft's asphalt 7 supports it and the game will install but then says: 'unsupported version' after starting game

[deathkill]

and astro filemanager doesnt see internal storage.. is it ext4 or something?
the build in file manager however can't access network mounts..

any suggestions on a file maneger that supports the internal storage and can connect to sftp/smb?
