Cannot share videos with NFC

OK, so I have a Nexus 7 and a Galaxy S3. Both have NFC and it is turned on for each. Android Beam is also enabled.
I pull up a video on the S3 and bring it close to the N7 and the S3 video screen shrinks and the "Touch to Beam" prompt appears, so I tap the S3 screen. Then an animated graphic appears and the message "Ready to send files via S beam. Separate devices". In the status line on top of the S3 there is a downloading symbol flashing.
Then I slowly seperate the devices till they lay side by side. The S3 status line no longer shows a download and it continues to play the video; the N7 shows the message "New tag collected" and under it it says "text/directsharevideo". The N7 screen is unresponsive unless I use the home key to exit.
I have no evidence of anything actually being transmitted between the devices.
What am I doing wrong?
p.s. I did search both Google and XDA. If anyone can suggest a better search string than the title, please do.

I think you need JB for transmitting videos/images via NFC and the S3 is only rocking ICS.

Thanks for the heads up

I believe its to do with the tech they use to transmit after the NFC handshake.
GS3 uses WiFi to transmit and N7 used bluetooth.
I dont believe they are compatible, they can use tags no problem, but GS3 can only use NFC with other phones using WiFi Direct tech.
Hope this helps

Android Beam was not designed to send large files (NFC transfer protocol itself is very slow)
This is why Samsung made S-Beam on their s3 (NFC + Wifi Direct) so you can transfer any files you want, the only issue is both devices need to have s-beam.

Android Beam, from Jelly Bean upwards, uses NFC to initiate a Bluetooth connection. It's now possible to transfer larger files with Android Beam, though not as quickly as S-beam.

if you want to connect from android device to android device for transmitting media, check this one:
https://play.google.com/store/apps/details?id=com.budius.WiFiShoot
this was developed by yours truly, and I developed it exactly because I noticed there was nothing out there for WiFi Direct
I tested it between Nexus 7, Galaxy Nexus, Asus TF300 and Galaxy SII (stock ICS) and all worked fine.
The most problematic of those were the Galaxy Nexus that now always want to connect, but between N7-GalaxySII was flawless.
At the moment the app just works for photo and video but I'll be expanding more, if you guys fancy helping spreading the word about it, I'm really looking forward to see the downloads explode on it.

Hi guys,
is anyone with interested in beta test my WiFi Direct app?
I started a new thread in the development section asking for Logcats if you're experiencing force close.
Also it's a cut down version of the .apk there to test part of the system.

any help will be great appreciated.

How can I send files to my Nexus via Bluetooth?

OK, I understand the mechanism, and I can easily transfer files from my Nexus to my Note using Share -> Bluetooth. The two devices are paired. The trouble is that the confirmation dialog that I get on the Note when I send from my Nexus never appears on my Nexus when I try to send from my Note. The Note just tells me it failed after a few seconds.
Is there something special I need to do on the Nexus to allow it to accept BT files?

NFC stopped working

I got a new google nexus 7 two weeks back. The Android Beam worked fine with both tags and other devices.
All of a sudden it stopped working.
I remember that I kept on my DVD player for long.
No tags can be read or written apart from no NFC sensing with other devices.
How do I debug?
The kernel is 4.1.2. Please help. I am not sure if it is a hardware problem.

Settings -> Wireless and Networks -> More
Make sure NFC has a checkmark. Should say Android Beam is ready.

Yes NFC is checked and Android Beam is on and ready to beam
I tried to test it with tags and galaxy s3 which were working fine with my nexus 7.
All of a sudden NFC has stopped.

If convenient, just exchange it. Sounds like hardware failure.

Thanks that is the last resort. But was looking for some debug messages etc to verify the hardware failure so that the vendor is also convinced regarding the failure and provides the exchange.

Use a USB cable or send files over WiFi using "Air droid" app.

That's like saying "take the train" to someone that has car trouble and can't get to work--not very helpful. What if they need to use bluetooth due to lack of USB cable or a wifi-capable computer? I know it's not probable, but the bluetooth capability is there and should be able to be used if desired, even if it's not the fastest data-transfer method.
I too, have the same problem, though just two days ago I was able to send files.

Can't help you much as I got Windows 8 and Ubuntu.
But I had this kind of problems often on Windows 8, I had to unpair (from device and phone) then pair them again, each time I had to switch from Linux to Windows.
Anyway, to send files by Bluetooth from windows, try this:
Right-Click on the file
Then Send to
And choose Bluetooth Device
I never opened the storage card of my nexus from bluetooth on my PC, I think the connection is not very stable.

SBEAM/NFC Issues

Is anyone else having issues receiving files, pictures, music etc...using S-BEAM/NFC? (I have both options selected)
I tried sending files from a GNII and a SIV to the N7.2 with no luck what so ever. When beaming the files to N7.2 I get a Play Store prompt and it eventually times out.
However sending files from the N7.2 I never have any issues.
Has anyone else experienced this?

S beam will have to be turned off when using the Galaxy s4 or S3. It works but you have to use regular NFC with devices that don't have s beam. If you are looking for something similar from Android to Android device try super beam. This application does the same thing similar to s beam.

I can't get my NFC to work at all. It is on in the settings but it won't recognize any NFC device when bumped (tried with old N7 and S4). I even used a reader app to read my credit card and it didn't even pick that up (which my GS4 did with the same app). So NFC seems to be the only thing wrong with mine. If there's a fix that doesn't require a return or sending it in, that would be great.

As stated... With any Samsung galaxy device s beam has to be turned off and NFC only turned on.

Thanks for responding!
I turned off S Beam on the GNII and I was still not able to send picture using just NFC. I tried with S-Beam off and also with Android Beam off. With Android Beam off, it was really a no go. With Android Beam on, it would attempt to send the file, but the N7.2 would go to the Play Store, the same way it would with S-Beam on.
I am going to get my coworks GS4 and turnoff S-Beam to see if its an issue with my GNII.

On the Nexus 7 (2013), the NFC sensor is in the middle of the "nexus", in the same place as the wireless charging spot. On the Nexus 7 (2012) the sensor was towards the top of the device around where the "nexus" was. I have found the NFC signal to be exceptionally strong on the Nexus 7 (2013).

NFC from HTC one
Hi, I can use the same MiFare tags on either device but for the life of me cant get any connection between my HTC one and the Nexus 7 (2013). Its bothering me since I know both transceivers work. Is there some incompatibility? Before anyone replies, I am not a moron and yes all NFC options are turned on. I tried BT on/off too. I rebooted etc. Anyone?

I just tried using my coworkers GSIV and I could send a file from the N7.2 witout any issues. The phone actually had S-Beam on when I sent a file from the N7.2
I asked her to turn off S-Beam and to send me a picture from the GSIV. No good, the picture would not send. We turned S-Beam on and tried to send a picture and the Play Store option popped up on the N7.2.
Could it be that I just have a bad unit? I don't not have any other NFC enabled devices besides Galaxies devices around me lol...so I don't have any other way to test it out.
Sending from the N7.2 is great...receiving has been a failure using the GSIV & GNII.

Android Beam is built into every Android 4.0+ device with NFC. However, as of Android 4.1+, it can send photos and videos to other devices, so long as both devices have Bluetooth in addition to NFC. Simply open a photo or video in the gallery, put the devices back-to-back, and follow the beam procedure.
S-Beam is a proprietary implementation of this on certain Samsung devices, which predates 4.1's photo/video sending capabilities, and uses Wi-Fi Direct. Since it is uncertain if S-Beam disrupts the function of the Bluetooth-based Android Beam photo/video sharing, and only offers a few extra file sharing features, I would recommend turning it off, unless you have compelling reason not to.

Thank for the tip. Once I was able to find the "G Spot" I was finally able to send pictures and apps from my GNII to the N7.2!!! Now I just need to try out my NFC chips!!
Whew...I'm happy that its not my phone or the tablet...just took a more precise and gentle touch lol :highfive:
