nfc-p2p

Currently using React Native and attempting to use react-native-nfc-ios and react-native-nfc so I can have cross-device communication between ios and Android. I'm finding that they cannot communicate, however I think it's due to a broader issue (as other existing apps also don't work). If I download a NFC reader app on iPhone 7, and an NFC writer app on Android they cannot communicate. Why is this? Instructions to Duplicate Turn on NFC Reader on iPhone 7 Put some arbitrary data in NFC write mode on Android Bringing devices together has no effect. Not understanding the intricacies of NFC, it's

I am trying to implement a P2P communication between two Android phones (one of them will be replaced by an independent device in the end). I have seen that Android 4 supports SNEP which is published by the NFC forum and should be available on non-android devices. I have following the Google tutorial for NFC P2P (http://developer.android.com/guide/topics/nfc/nfc.html#p2p) and I can send some information from one phone to the other, but I have a few questions: Android Beam is just a name for NFC or it is an Android protocol working over SNEP/NPP ? If it's a protocol, how to do NFC P2P without

Ok, I watched the Google I/O from 2011 presentation on NFC on peer to peer. The demo was done on Gingerbread and using the application Sticky Notes found Now in this demo, both device the onNewIntent() was called at the same time so both devices are trying to share information to one another. On ICS and above, you have Android Beam.. With Android Beam, you have to touch to trigger the onNewIntent() event that will send the NDef message across. Now the problem with this is that now to trigger the onNewIntent() on both devices, both user on each device has to "Touch To Beam" at the same time. Is

I have an NFC reader ACS ACR122U and I want to send data from my Android phone to it. I have found many examples on how to connect my two devices in P2P mode and how to send data from my phone to the ACR122U, but my desktop server (ACR122U) always receives a SNEP PUT request. I would send a GET request but I can find only examples that use Android built in NDEF system without specifing PUT or GET request. How can I package and send a SNEP GET request from my Android device to an ACR122U? Short answer: You can't. The Android API does not allow you to implement custom LLCP services. The only

I used the ACR 122 before and it worked flawlessly with an Android < 4.1 phone. I used it to exchange P2P SNEP messsages... But since the phone got 4.1, the reader starts beeping and flashing when you place the phone above it. Does anyone else have found this incompatibility? Any solutions? Since Android 4.1 Jelly Bean, NFC peer-to-peer communication is configured to use a higher bitrate (212 kbps), while earlier it was using 106 kbps (in Android devices that have Google Wallet installed it was always using 212 kbps). I don't know whether the ACR122U can support the higher bitrate through

Is it possible to establish connection between Galaxy Nexus Jelly Bean (4.1.1.) mobile and any regular desktop contactless reader (ISO 14443 A/B)? As I know, android does not support card emulation mode, so it should be done only by p2p mode. Is p2p based on ISO 14443, so any reader can be used, or it needs also a specific NFC chip, not the standard ISO14443 chip used in older readers? The answer to your first question is yes, the GNEx should support ISO 14443 A/B. I'm not sure what you're asking in your second question, but I can tell you that one of the readers must be of one of the formats

I am trying to send NFC data from one Android device to another. I was able to do it successfully using the 'Touch to Beam' functionality. But I would like the data transfer to take place automatically as soon as both the devices are together. I saw this question answered in StackOverflow multiple times. Unfortunately, while some say its not possible to send NFC data from one Android device to another this way, some others suggest to try "foreground-dispatching" (which the official documents say is now deprecated). I wasn't successful with "foreground dispatching" though I am not entirely sure
