Hi Pär

I know I am way off with the deadline but I was wondering if there was still an Arduino Primo available from the original batch of 20.

With it, I would like to create a prototype of a system for the automation of already existing home appliances.

Thanks a lot

Simone

Hi, Kenneth! I have making universal wearable input for smartphone, PC, VR&AR system. It may be used for navigation, control, input text.

Hi there,

We are looking into creating a Google code lab for introducing the API to developers, but haven't started that work yet.

I have a small demo app: webnfc-shoppingcart.appspot.com which works on Chrome on Android. It works with trunk, but I haven't checked the Dev Channel yet, but it should work with that very soon. If not, we can build an APK for you.

It requires you to turn on Experimental Web Platform features in the about:flags page and restart the browser.

Now you are asking, what kind of resources would be helpful to you?

Hi Kenneth,

I 've been working with the Web Bluetooth API and am curious about Web NFC. I would be happy to help try out features of the specification as it evolves, especially related to the nRF52 DK and Arduino Primo.

Do you have any recommended resources for getting started with Web NFC other than the official spec?

Thanks, Ketil

AFAIU, the device can function as a NFC Tag type 2, so that should be fine, and should work out of the box with Web NFC.

Making the device API able to deal with JSON directly would make it easier to work with. With something like JerryScript that can be easily done on top of any existing device API.

We haven't looked at handover yet, but Physical Web + Web Bluetooth will do similar handover, meaning that there will be a referringDevice connection which will only exist when launched from a Physical Web beacon. Doing something similar for NFC makes a lot of sense.

Kenneth, That is really cool!

What functionallty do you need on the NFC device to work on this Web NFC? Currently the nRF52 supports Tag typ 2.

Cheers,

Pär H

I would like getting hold on the device because it supports both Bluetooth and NFC.

the nRF52 chip is supported by Zephyr which has a port of JerryScript. I have already gotten the Arduino 101+Zephyr+JerryScript combination running in a configuration where the device used Physical Web to announce its web app which then could connect to it and communicate.

As I work on the Web NFC spec https://w3c.github.io/web-nfc/ the device is really interesting for playing around with NFC on both device and client (web site) side. I am also planning to look at Bluetooth handover from NFC for Web Bluetooth/Web NFC at some point - any help, ideas for the spec with regard to that is welcome! :-)

The idea is to implement a semi soft UART for the second interface, to provide an extra UART. Also, it is possible that the I2C connection between the nRF52 and the STM will take over some of the tasks intended for the UART connection, to allow the second UART to be available to the application instead.

Both the STM and the nRF52 can be programmed through the SWD headers, that is correct. One of the headers can also be used as an output, allowing the Primo to program external boards without a built in programmer.

The WiFi chip supports IPv4 only. For IoT the idea is to use something like the Arduino Tian: http://www.arduino.org/products/boards/arduino-tian

Looks interesting - looking at the links I had a couple of questions

Is the Primo Chart correct download.arduino.org/.../primo_chart_20160714.pdf because that shows the nRF52 communicating with both the STM32 and the WiFi chip over UART, but the nRF52 only has one UART so that didn't seem quite right.

It says "Programming via OTA or via Serial", I'm assuming you can also program it via a normal ARM SWD header and a segger, the picture makes it look like there are two of them, one for the nRF52 and one for the STM32?

Does the WiFi support IPv6 or is it just IPv4, last time I looked at that ESP8266 chip the standard firmware was IPv4 only but expressiv were supposed to come out with an IPv6 version.

I thought it would be fun to use something like that to develop an easy config WiFi/6lowpan BTLE border gateway, like you can with a Raspberry Pi, but self-contained. However I don't think the IoT Softdevice supports more than the client side of the 6lowpan so it's probably not possible.
