That's because v170 doesn't have nfcd running by default.
If we use v170, all NFC tags/devices won't be detected.

Even I flash my two Flame devices to Android (2/27) 
with system property
[ro.build.fingerprint]: [qcom/msm8610/msm8610:4.3/JLS36C/eng.archermind.20140213.193200:eng/test-keys].

The two Flame devices still keep 'beaming' (NFC beam)

I check the log, 

There's always an error callback from the libnfc-nci

llcp_link_deactivate () reason = 0xb0 (LLCP_LINK_RF_TRANSMISSION_ERR)
llcp_link_deactivate () reason = 0xfc (LLCP_LINK_RF_LINK_LOSS_ERR)
llcp_link_deactivate () reason = 0xb2 (LLCP_LINK_RF_TIMEOUT)

And if I replace one Flame to other device(Nexus 4, or Nexus 5)
and it will be okay.

NFC Beam is just happening once.


So I think the problem is from the libnfc-nci, not from nfcd nor Gecko/Gaia side.
De-assign myself.

Also I spotted one thing, the back cover will also affect the NFC functionalities.
If I took the back cover from device A to device B, then device B (with back cover from device A) couldn't use NFC at all. (I use a NFC tag, or a Nexus 4 , Nexus 5 device to tap device B, I've tried around 5 minutes, I think I only get no more then 3 TechDiscovered callbacks, but if I take the back cover from B back, NFC on device B is working again.)

Captured Video, please start with 00:15
I only have two hands and I have to take 3 devices, I wasted about 15 seconds to figure it out. :P

Also I try to look at both devices to see their screen is unlock, so you can see I keep looking at both devices.

Finally I put them on the desk.

Sorry I found I use 1080P as video quality so the files are huge (200+MB),
I try to make the video quality poorer, and record Flame and Nexus 4 at the same time,

It's smaller now but it still needs 50+ MB.

hi Yanan,

can you double check NFC solution on V10D?

Comment 16

[Walter Chen[:ypwalter][:wachen]]

Al, is that the V10D(B1TC100110D0)?
Dimi and I actually verified that NFC working fine in V10D. I also tested it few minutes ago and it worked alright. I can't actually get anything from logcat like you get. Do you need a fresh flash for V10D-1?
