 Hello and welcome. Thank you for joining. My name is Damien and I'm an engineer at ST Microelectronics. I'd like to present in this video how the ST25-DV dynamic tag can help developers like you solve real-life industrial problems. As such, the ST25-DV tag allows the I2C bus of a microcontroller to interface with the external world via radio frequency interface. The kit is divided in two parts. The first one is the motherboard with STM32-F405 controller and the other one, the daughter board is based on the NFC RFID ST25-DV04K device which is ISO 15693 and NFC4M type 5 compliant. Now, let me show you the setup. We're using a long range LR1002 reader from our friends at Feg Electronic. The RF reader is connected to a 30x30 industrial grade antenna also by Feg Electronic. Those are products that you can buy off the shelf. In front of the RF field generated by the antenna, I'm going to place a bag full of ST25-DV Discovery kits. Those kits can be ordered online at the address shown at the bottom of the screen. With a free software download and an RF reader, we will see how far devices can be detected. This range can be a key factor when detecting switched-off items on the production line, for example. Finally, you will need to download and install the ST25PC-001 from the ST website. Now, let me show you the inventory process on the software. As you launch the ST25PC-NFC software, you can see at the bottom right the connection status of the reader. Here it says LR1002 Connect. You click on the reader menu, and in the inventory, detect all the tags in front of the antenna. In continuous scan mode, the software launches a new inventory process at regular intervals. This allows you to find the range of operation of your tags. As you're watching, all the ST25-DV Discovery kits from this box are detected within 30 cm. In addition to doubly-pronged memory, where you can store custom data, the ST25-DV tag embeds 256 bytes of fast memory. This memory can be used to transfer information quickly between the RF and the I2C interfaces of the tag. One of the applications of this fast transfer mode is to transmit large files of 100 kilobytes from a reader to an electronic device for reprogramming. Let me now show you how the ST25-DV tags can be used to reprogram several electronic devices at the same time. The reader setup is the same as for the inventory, except for the antenna is not being oriented vertically. I have added four ST25-DV Discovery kits on a stand over the reader antenna. They are powered through a USB cable, and an antenna card is connected to each board. Back to the software, we make sure by running an inventory again that we see all four devices that we want to reprogram. Then we go on tags, ST25-DV, fast transfer demos, and firmware upgrade menu. And here I will select a binary file of about 110 kilobytes that I will send to the boards for reprogramming. You can see that the firmware transfer is happening through all four devices simultaneously. This can be useful to maintenance or support organization when having to reprogram devices on the field, for example. We have accelerated the transfer that took about 52 seconds with the FEG LR1002 reader. You can see that the CRC was verified successfully on all four devices, and that the firmware version has updated to 200. I hope I got you interested in the potential of ST25-DV dynamic tags for industrial applications. Thanks for watching!
