Wired headset buttons cause no reaction.

[Giangiva]

I have a Mi2S 32GB bought directly from xiaomi.
I also own a wired headset from xiaomi as well, which is working fine with the MIUI rom (ok, it's not the best, but it's working... :-) )
When plugged in the phone using this rom, I can hear the sound through it, but pressing the buttons has no effect.
I even tried watching the logcat, but I couldn't notice any change in it when pressing the buttons on the headset.

This seems to be the device:
I/InputReader( 568): Device added: id=3, name='apq8064-tabla-snd-card Headset Jack', sources=0x80000000

I think we need to create "apq8064-tabla-snd-card_Headset_Jack.kl" but I don't know the keycodes for this device and I don't know how to find them, too. Any idea?

I have installed the cm 10.2 4.3.1 made by cofface in my system2: do you think I can get those keycodes using that rom?
Or, since your kernel is different, also the keycodes will be different?
btw, is this a problem only on my phone (Mi2S) or do you see it in your one too (you own a Mi2, don't you)?
Another idea: since the device seems to be created, can't we read its events from any place in /proc or in /sys?

I don't know if that works but you could try to get the keycodes via CWM.
advanced -> key test

I tried it, but I got no reaction... :-(
The only code I got is the one for the 'back' key that I pressed to get out of the key test.

Does this app show the keycodes?

Unfortunately, not.
I can see other buttons with it: menu, back, but nothing happens when I press the keys on the headset.

I have Klipsch earphones (w/ microphone and single button), which work fully on Miui w/ MI2S 32GB.

The "key test.apk" does not register any key press for the earphones button, while CWM reports ScanCode 256.

Just for the information of those interested: from the view point of plug wiring, MI2 seems compatible with iPhone with the only difference that volume +/- buttons (if exist) do not work on Android. This is IMHO true for any recent Android devices (e.g. last "smart" Samsung with the old "nokia" style was SGS i9000). There are available simple adapters, which switch the mic & ground. The two existing "standards" are shown at the attached picture.

Ivan's ROM (see the other issue #6 ) reads the Scan Code as 226.

Hi M1cha,

today, with the 3/12/2013 release, I tried again the wired headset: no luck.
Then I tried with the key test in the cwm recovery: success!
The "play" button is code 256
The "forward" button is code 257
The "rewind" button is code 258
Given that, now, the system seems to be able to read the keys, how can I "convince" the apps to do something with these keys?

Hi Guys,

I have the same problem, am using an IPhone headset. During Phone calls the mic doesn't work. I can hear the otter person, they can't hear me

[M1cha]

Vosje: that's a different problem and has nothing to do with this issue.

Ok sorry, I'll make a new post for this one then.

I’ve tested this, the internal mic doesn’t work when I connect my headset

does that work?

Nope. Flashed it and cannot see any change. No reaction, Key Test apk does not notice the presses either.
