NFC-A tags are the most common tags (for example, both the MiFare DESFire and specialized chips like the ones in electronic passports use NFC-A), but you may experience problems if you use other tags. Also, at the moment, every tag technology supported by Android's HCE is supported (A, B, F), however NFC-B and NFC-F remain untested. When in doubt, use an application like NFC Tag info to find out if your tag is compatible. For example, Android no longer offers support for MiFare classic chips, so these cards are not supported. We can only proxy tags supported by Android. Compatibility with Cards (relay, replay, clone) Keep that in mind while performing your own tests.

We may or may not get around to implementing cryptographic protection, but for now, consider everything you send over the network to be readable by anyone interested, unless you use extra protection like VPNs. Right now, all data in relay mode is sent unencrypted over the network. Most of the phones should implement this specification when offering HCE support. When using modes, that utilize HCE, the phone has to implement the NFC Controller Interface (NCI) specification. Please consider the following issues and caveats before using the application (and especially before filing a bug report). For further notes on compatibility see the compatibility document. A detailed description of the import and export functionality is documented in doc/pcapng.md. For example, Wireshark can be used to further analyze NFC traffic.

This application was developed for security research purposes by students of the Secure Mobile Networking Lab at TU Darmstadt. It can be used as a researching tool to reverse engineer protocols or assess the security of protocols against traffic modifications. Slave disconnects right after switching connection interval time.NFCGate is an Android application meant to capture, analyze, or modify NFC traffic. We don't seem to have this problem with later versions of Android (such as 9.x), but I don't have one here to try with Wireshark to see if its order is different. Does the BLE stack get confused and disconnect if the LL_CONNECTION_UPDATE_IND comes before the L2CAP acceptance of the request? We get the same results when we change the requested range of the connection interval (e.g.- 100-200 msecs, 200-400, 20-200.) and the Android system always picks an interval within the requested range, so that doesn't seem to be the problem.Дoes the order of the master's response matter? The order that works matches what you show in your Peripheral Connection Parameter Update message sequence chart ( ). We are using an nRF52833 with S113 SoftDevice, and version 17.0.2 of the SDK. The host eventually gives up due to the lack of responses and also disconnects.After that the slave immediately disconnects, stops responding and starts advertising again.

At the proper time, the two sides change to the new connection interval for just the first interval.At the proper time, the two sides change to the new connection interval and everything is fineД«ut with the Android 6 tablet, the order of the Master's packets is reversed, and the slave (our device) disconnects right after the interval switch:.Master sends LL_CONNECTION_UPDATE_IND with details of the new parameters and when to switch.Master sends L2CAPВ Connection Parameters Update Request (Accepted).Slave sends L2CAP Connection Parameters Update Request.Wireshark shows the following packet sequence. But with an Android 6 tablet it disconnects right after the switch to the new connection interval. Our peripheral application sends an L2CAP Connection Parameters Update Request to change the connection interval 30 seconds after connecting.
