NXP Controller HCE for Google Wallet

abuttino · Jan 2, 2014

Once you have everything decompiled, I'll start to get another email campaign going to Dan Rosenberg, koush, hashcode and maybe dhacker. If they can solve it, it'll get merged. Hopefully they can help, otherwise, I'll call in some others.

The oppo has NXP? That is kind of odd, I would figure that they'd put it together with a working wallet

Lots of devices have NXP chips. The Galaxy S4 is one of the only non-Nexus devices I know of with an NCI-compliant chipset (These are all Broadcom chips, but apparently NCI is not a division of Broadcom but a new standard for NFC controller interfacing). Sony Xperias all use NXP chips too.

This should mean the pressure is on for Google to release the chipset drivers if they cleared the oppo for CM.

Edit: either Google or NXP should be under pressure.

Good news! I've contacted Google Wallet tier 3 support, and from what the advisor told me, I understood he might be pushing the Android Development team to include the NXP stack in 4.4.3. Don't take my word for it, as he said he "may not release confidential information to the end-user"

Wow, amazing. Please pm me how you got in touch with him. I'll put a professional letter together that will gain some more attention.

No reason for this, considering that:
1) They only approved 4.3 on the N1
2) HCE support is not required for GMS approval on KitKat as evidenced by grouper and tilapia

I just received my first NFC-enabled debit card today, and am saddened to find that my phone is still unsupported, unless there is something I missed. Has there been any further progress on this project?

We are still waiting for him to finish decompiling the files.

Sorry for the delay guys, I manage a retail store, and had to get through some cleanup projects that stole all my time. I intend to work on this later tonight and tomorrow.

Okay, so this is probably a really stupid question but what exactly are we looking for? I'd love to help out and have tons of time on my shift to sift through these files if i knew what i was looking for...

What we are doing is decompiling the jni code for more experienced coders to discover what code is missing from the HCE driver, then to add that code to the AOSP HCE driver.

Where are the hce drivers located?

Posted from my Outlaw(unlocked) XT926, Verizon can suck it.

The code is somewhere in the files that I posted last night. The challenge is to find it.

I meant where's the original HCE to compare it with...?

abuttino · Jan 16, 2014

It's in any NXP Google Edition phone's ROM

HTC one, LG G2, etc.

I don't know if this link is of any help to find what we are looking for. https://jira.cyanogenmod.org/plugins/servlet/mobile#issue/CYAN-2935

Disregard.

Azbulldog · Feb 4, 2014

Any further developments?

abuttino · Feb 5, 2014

Unfortunately not. The Google wallet team is on this as well. We should see something in the next Android version if anything.
