Transfer files NFC

[JoseParticipant]

Good morning, my name is José Antonio.

I have the ACR1255U-J1 device and I need to transfer files between PC (Windows) and mobile (Android / IOS) through nfc technology. Can your software transfer files between PC and mobile?

Hi Jose, in theory yes this is possible but in practice it may not be the best option. It depends on the size of the file you want to transfer and what other wireless mediums you could potentially use. For instance, our Flomio SDK support Bluetooth Handover which allows NFC to trigger a Bluetooth connection which can then transfer the file data faster and more effectively. If transferring the file data via NFC is your requirement then we will have to implement a serial protocol driver for you to interface with along with all the possible error conditions.

Can you share your particular use case? We offer Flomio Service support to help meet our enterprise customer needs, perhaps it’s of interest to you.

best,
Richard

Hello I would be interested in your software but I need to clarify some doubts:

1.- PC Windows OS connection with NFC device

2. File transfer

3.- If the PC-NFC connection is via bluetooth

4.- If the connection with the user is by means of NFC and only NFC or on the contrary the user must activate bluetooth and pair with device

Hi Jose, answers inline below:

1.- PC Windows OS connection with NFC device
> Yes, Windows PC can connect to our NFC devices over Bluetooth. This will be using our latest Flomio SDK written in JavaScript and leveraging the NodeJS framework.

2. File transfer
> I need to better understand this requirement in order to properly answer. For small files (<1kB) NFC transfer is possible. For larger files, other wireless links are more suitable.

3.- If the PC-NFC connection is via bluetooth
> Yes, PC-NFC reader connection is via Bluetooth Low Energy (Bluetooth4.0+).

4.- If the connection with the user is by means of NFC and only NFC or on the contrary the user must activate bluetooth and pair with device
> Need to better understand what you mean by “connection with the user”. The NFC reader is able to read an NFC passive target and will relay that information read over Bluetooth to the PC. Essentially, the reader is an NFC-to-Bluetooth Gateway device.

Hi Richard,

I want to transfer the file via windows using NFC to a mobile device.
The device ACR1255U-J1 have can transmit up to 424kb/s.

Jose

[RichardKeymaster]

Understood. The default rate of NFC data transfer is 106kb/s as per specification. Higher data rates can be negotiated but will depend on the capacity of your target which may be limited. For instance, the iPhone is not currently capable or negotiating the higher data rates.

Hi There,

I’m working on the development of software that aims to send a file from a OS Windows computer to an Android App through an NFC device. The device is ACR1255U. I’m interested in the Flomio API. But I have some doubts that I would love to be solved.

1.- The Flomio SDK helps me connect the NFC device to the computer and send files through it?

2. Can the file sent from the computer through the nfc device go to an Android application?

[RichardKeymaster]

Hi Jose, yes to both questions. However, this is not a simple task as you will need to serialize for file, send it in 16 byte packets, and monitor proper receipt and sequence.

best,
Richard
