When the application starts, it initializes and starts the NFCT peripheral, which is used for pairing. The application does not start advertising immediately, but only when the NFC tag is read by an NFC polling device, for example a smartphone or a tablet with NFC support.Wireless NFC Reader µFR Nano Online - Bluetooth Low Energy (BLE) HID mode
The message that the tag sends to the NFC device contains data required to initiate pairing. After reading the tag, the device can pair with the nRF52 device which is advertising. Connection state of the device is signalled by LEDs. When the connection is lost due to timeout, the library automatically triggers direct advertising. Since the SoftDevice does not include the functionality required to calculate Elliptic Curve Cryptography ECC public keys and shared secrets, an external library is required for this purpose.
Bindings and build files are provided for a well-known open source library, micro-eccalthough the library itself is not provided. To use micro-ecc with this project, follow the steps described in Software backend micro-ecc.

Quick question, why would the Product Specification document specify TX and RX frame starts and ends, size, etc if the hardware can't do bi-directional communications? Also, from the link Bjorn posted:. Why would it be able to disassemble frames if it can't act as a reader? From what I can understand with e-mail communications with Nordic is that bi-directional communications are possible on hardware level, but the library does not support it, which leaves the user to have to write their own library.
I have logged a ticket as suggested regarding more information about library development for two way communications. It would be interesting to hear comments and I will also give feedback on gained knowledge. Even if you emulate card PICC aka slave you do bidirectional communication. Alternatively seems more likely given the level of your questions you should seek some expert and subcontract the job externally.

My apologies - I have posted this as an answer, so posting it here as a comment Hi guys.One thing I notice in the fast-moving mobile payment space is the constant struggle for accuracy.
In this case, I don't exclusively refer to location-based accuracy though we will get to that momentarily as much as the struggle over the literal meaning of words. Case in point: iBeacon.
When word began spreading about Apple's iBeacon last fall, many observers proclaimed the technology would supplant Near Field Communications as a mobile payment medium. But that's apples-and-oranges. The iBeacon and PayPal's Beacon, which rolled out about the same time are not, of themselves, a technology. They are but an extension of Bluetooth Low Energy, which has been around for almost a decade. Think of it this way: Cellular communications provide wireless coverage with a footprint measured in miles; WiFi's footprint is measured in yards; BLE's is measured in feet; and NFC's in centimeters.
As this infographic illustrates, a BLE beacon is great for passively enabling a retailer's mobile app to deliver promotions, coupons or offers direct to the consumer's smartphone when the consumer is in the general vicinity. NFC can't do that. But if you want to research a specific Nikon SLR, for example, you can scan an NFC-enabled shelf tag next to it and study to your heart's content.
BLE can't deliver that much location granularity. To illuminate these two technologies, we developed this infographic in partnership with Pyrim Technologies. Read about it and debate it — and remember, while it's instructive to parse the finer points of BLE and NFC, it's not an either-or proposition. It's about choosing the right technology to appropriately address a specific business need.

All FloBLE devices have a Bluetooth connection range of approximately 50ft and include a push button to wake the device from sleep in order to preserve battery power. The Pro version upgrade here works completely offline for unlimited use. A special SDK library will be provided so Pro customers can create their apps for offline use. Richard — April 20, Easy to connect and includes a nice battery save mode as well as audible beeps when tags are scanned.
Read my NFC cards well and is small enough to carry around. Malik — December 18, This product provides the NFC functionality much like any other product in the market. I have been using this product for quite some time now and since the SDK is ever evolving, I have faced certain issues. A huge thanks to Flomio team who not only helped me solve those issue but also helped me understand how everything works.
Have a look to get an idea of the type of support they provide. James Seigel verified owner — May 31, Hardware seems good. The SDK could be tuned a bit. My team was having issues with some connectivity strangeness, probably due to trying to connect to licensing servers. It would be great if there was a way to try the higher level license to see if it would work better before committing to the cost.

Over the years various methods have been employed to gain visibility of each package through its supply chain as it is shipped from its storage location to its delivery destination.
RFID also enabled contactless location of packages in the warehouse or in-transit. To find these answers, let us walk through evolution of supply chain visibility solutions and compare each of these technologies namely - Barcodes vs RFID vs BLE Beacons along with their features and drawbacks. We will also see how NFC, a new technology that is coming up in the consumer space, fares in context of supply chain or logistics visibility.
Supply Chain Visibility 1. Barcodes are labels pasted onto products or packages with optical machine readable representation of data which denotes something about that package or product.
Barcodes evolved from one-dimensional to two-dimensional and recently to the popular QR codes which could enable the storage of a large string of data to identify a particular object.
Barcode technology with its optical scanners enabled supply chain mangers, for the very first time, to scan packages at any hub and link the data to a central repository such as an ERP WMS or TMS. Drawbacks of Barcodes :.
Further they could not locate a package in real-time. This led to experimentation with RFID technology. RFID technology employs tags which contain mini-circuitry that are identifiable by radio waves.
XS4 Wall Readers
Tags can be as thin as paper labels or the size of keychains depending on how much data strings it can store and the distance from which it can be read. RFID tags are broadly classified into passive and active tags. Passive RFID employs tags without batteries which draw power from the radio waves beamed by the reader and reflect them back to the readers. Once the reflected wave is captured by the reader, the tag and its parameters are identified.
Since the radio waves are reflected like a boomerang, its strength erodes swiftly by the time it is read by the reader — making the read-range typically less than 20 feet. Passive RFID tags are typically used for tracking low-cost items at gates and checkpoints of a warehouse where the read-range needed is low.
Active RFID employs tags with in-built batteries that can help extend the read-range to about feet by beaming its information towards the reader just like your mobile phone. Active RFID technology found its application when it came to monitoring high-value packages or equipment in warehouses, yards, and the railways. The high read-range enabled the readers to overcome the drawbacks of passive RFID solutions by sensing packages and equipment throughout the yard or warehouse with a limited number of readers, but other drawbacks prevented it from scaling.
Let us see what they were! Let us see how the beacons help address these drawbacks! They have inbuilt batteries which provide them with long read-ranges.
BLE is further a universally available protocol that also happens to be a feature present on most GSM chipsets in other words, your cellphonegiving BLE Beacons the strategic advantage in terms of cost effectiveness and scalability. NFC can function both like active or passive RFID, where-in the tag can simply bounce back radio waves it is beamed or actively emit radio waves towards the NFC reader using a small battery. NFC readers are common on smartphones today with most Android and Windows phones carrying them, but the biggest drawback of this technology is that its read-distance is extremely low in the range of a few centimeters only.
Is NFC effective at addressing supply chain visibility? Not really - if you are looking to secure a large warehouse with plenty of parcels without spending much time or person-hours. Since, close proximity is required to read packets or goods, it is almost the same as passive RFID, except that read errors or stray assets being read in the zone are minimized sometimes when compared to passive RFID due to the need of the asset coming in close contact with the reader.
BLE beacons on the other hand have a large read radius and are extremely low on power consumption for the range they cover. They also come without all the challenges that active RFID poses such as infrastructure and cost. In Summary. Save as PDF.
